PHP MySQL Introduction

2009-07-01T03:57:00.000-07:00

The MySQL functions allows you to access MySQL database servers.
Installation
For the MySQL functions to be available, you must compile PHP with MySQL support.
For compiling, use --with-mysql=DIR (the optional DIR points to the MySQL directory).
Note: For full functionality of MySQL versions greater than 4.1., use the MySQLi extension instead. If you would like to install both the mysql extension and the mysqli extension you should use the same client library to avoid any conflicts.
Installation on Linux Systems
PHP 5+: MySQL and the MySQL library is not enabled by default. Use the --with-mysql=DIR configure option to include MySQL support and download headers and libraries from mysql.com.
Installation on Windows Systems
PHP 5+: MySQL is not enabled by default, so the php_mysql.dll must be enabled inside of php.ini. Also, PHP needs access to the MySQL client library. A file named libmysql.dll is included in the Windows PHP distribution, and in order for PHP to talk to MySQL this file needs to be available to the Windows systems PATH.
To enable any PHP extension, the PHP extension_dir setting (in the php.ini file) should be set to the directory where the PHP extensions are located. An example extension_dir value is c:\php\ext.
Note: If you get the following error when starting the web server: "Unable to load dynamic library './php_mysql.dll'", this is because php_mysql.dll or libmysql.dll cannot be found by the system.
Runtime Configuration
The behavior of the MySQL functions is affected by settings in the php.ini file.
MySQL configuration options:
Name Default Description Changeable
mysql.allow_persistent
"1"
Whether or not to allow persistent connections
PHP_INI_SYSTEM
mysql.max_persistent
"-1"
The maximum number of persistent connections per process
PHP_INI_SYSTEM
mysql.max_links
"-1"
The maximum number of connections per process (persistent connections included)
PHP_INI_SYSTEM
mysql.trace_mode
"0"
Trace mode. When set to "1", warnings and SQL-errors will be displayed. Available since PHP 4.3
PHP_INI_ALL
mysql.default_port
NULL
The default TCP port number to use
PHP_INI_ALL
mysql.default_socket
NULL
The default socket name to use. Available since PHP 4.0.1
PHP_INI_ALL
mysql.default_host
NULL
The default server host to use (doesn't apply in SQL safe mode)
PHP_INI_ALL
mysql.default_user
NULL
The default user name to use (doesn't apply in SQL safe mode)
PHP_INI_ALL
mysql.default_password
NULL
The default password to use (doesn't apply in SQL safe mode)
PHP_INI_ALL
mysql.connect_timeout
"60"
Connection timeout in seconds
PHP_INI_ALL
Resource Types
There are two resource types used in the MySQL extension. The first one is the link_identifier for a database connection, the second is a resource which holds the result of a query.
Note: Most MySQL functions accept link_identifier as the last optional parameter. If it is not provided, the last opened connection is used.

PHP XML Parser Introduction

2009-07-01T03:42:00.000-07:00

The XML functions lets you parse, but not validate, XML documents.
XML is a data format for standardized structured document exchange. More information on XML can be found in our XML Tutorial.
This extension uses the Expat XML parser.
Expat is an event-based parser, it views an XML document as a series of events. When an event occurs, it calls a specified function to handle it.
Expat is a non-validating parser, and ignores any DTDs linked to a document. However, if the document is not well formed it will end with an error message.
Because it is an event-based, non validating parser, Expat is fast and well suited for web applications.
The XML parser functions lets you create XML parsers and define handlers for XML events.
Installation
The XML functions are part of the PHP core. There is no installation needed to use these functions.

Browser detection with php

2009-06-18T20:29:00.000-07:00

This tutorial explains how to make a code only works in one separated browser, I think that's useful to correct incompatibility of page style in some browsers.

In your page, put:

1.2.
3.$user_agent = isset($_SERVER['HTTP_USER_AGENT']) ? $_SERVER['HTTP_USER_AGENT'] : '';
4.if(strpos($user_agent, 'Opera') !== false)
5.{
6. echo 'code for Opera';
7.}
8.elseif(strpos($user_agent, 'Gecko') !== false)
9.{
10. echo 'code for Mozilla/Firefox';
11.}
12.elseif(strpos($user_agent, 'MSIE') !== false)
13.{
14. echo 'code for IE';
15.}
16.else
17.{
18. echo 'some other browser';
19.}
20.
21.?>

mySQL Grant Command

2009-06-18T20:23:00.000-07:00

You can use the mySQL GRANT command to give priveledges to users to a specific database.
The syntax is as follows and follows the standard mySQL keywords and syntax you would perhaps use in a PHP script.
Code: [hide]
Code: [show]
GRANT privileges
ON databasename.tablename
TO username#host
IDENTIFIED BY "password";
The priveledges you can grant to a user are vast and for added security, you should only grant permissions to a users on a database that are requried by your application:
*ALL (all privileges)
*ALTER
*CREATE
*DELETE
*DROP
*FILE
*INDEX
*INSERT
*PROCESS
*REFERENCES (not used currently)
*RELOAD
*SELECT
*SHUTDOWN
*UPDATE
*USAGE (can connect but no privileges)
*Example use of the above syntax and privileges:
*Code: [hide]
*Code: [show]
GRANT SELECT, INSERT
ON mydatabase.*
TO user#domain.com
IDENTIFIED BY "somepassword"
The above wildcard (*) will replace the entire list of tables in the database. You can specify just specify one table name if required. You can also specify an IP Address for the domain part of the "TO" command.
You can revoke privileges using the following syntax:
Code: [hide]
Code: [show]
REVOKE privileges
ON databasename.tablename
FROM username#hostname
Usually, only server administrators should worry about this kind of permission configuration. If you are a normal webmaster using a typical control panel such as Cpanel - all this is done behind the scenes and you will not need to worry about setting up such code.

PHP Operators

2009-06-18T20:17:00.000-07:00

Introduction
An operator is used to operate on values. In a basic example, we use an addition operator to add 1+9 together. In another basic example, we use a subtract operator to take away 1 from 10 (10-1). PHP Operators are split into the following categories and shall be explained later in the article:
*Arithmetic Operators
*Assignment Operators
*Comparison Operators
*Logical Operators
Arithmetic Operators
1.Addition (+), eg: x+y
2.Subtraction (-), eg: x-y
3.Multiplication (*), eg: x*y
4.Division (/), eg: x/y
5.Modulus (%), eg: x%y
6.Increment (++), eg x++
7.Decrement (--), eg y--
Assignment Operators
1. =, eg: x=y
2. +=, eg: x+=y, AKA: x=x+y
3. -=, eg: x-=y, AKA: x=x-y
4. *=, eg: x*=y, AKA: x=x*y
5. /=, eg: x/=y, AKA: x=x/y
6.%=, eg: x%=y, AKA: x=x%y
Comparison Operators
1.Not equal to (!=), eg: 18!=13 returns true
2.Greater than (>), eg: 18>13 returns true
3.Less than (<), eg: 18<13 returns false
4.Greater than or equal to (>=), eg: 18>=13 returns true
5.Less than or equal to (<=), eg: 18<=13 returns false
Logical Operators
1.And (&&), eg: (1<2>4) returns true
2.Or (), eg: (1==5 2==10) returns false
3.Not (), eg: !(5==10) returns true
Conclusion
Operators are mainly seen during assignment of a value to a variable or during a conditional statement or a looping structure. They are very powerful are can be used to determine the output of a script, procedure or function to be run.

Looping with PHP and for()

2009-06-18T20:13:00.000-07:00

Introduction
The for() function is an iterative function. The word iteration is basically a posh word for looping. You use looping to avoid spaghetti code, and generate a list of output without having to type it all manually. For example, a looping function, for() can be used to loop the 10 times table without having to type it all out manually. Of course, there are much more practical uses for for(), but this tutorial is to tell you how to use this function so you can integrate it into your own projects.
The function
for() loop is used to loop for a set number of iterations. The function takes the following syntax. The following syntax illustrates the function using pseudo code.
Code: [hide]
Code: [show]
for ( initialize a counter; conditional statement; increment a counter)
{
do this code;
} 'initialize a counter' is used to set a start value for the loop. For example, we want to stop looping from the value 0, we set the initialisation counter as 0. 'conditional statement' is used to set a stop value for the loop. This is usually in the form of a conditional statement or in the form of a set value. Thinking about it as a stop value, we can set this to 10. 'increment a counter' is used to set the amount to increment each iteration. For example, we could set the for() loop to increment + 2 each iteration, or + 1 each iteration (in which cause you would use ++ operand). Example Code
The following is an example use of for().
Code: [hide]
Code: [show]
$num = 10;
for ($i = 0; $i <= $num; $i++)
{
echo $i;
} The above code will increment +1 each iteration, from a start value of 0 to a stop value of 10. On each iteration $i is echoed. The second parameter 'conditional statement' can take many forms such as sizeof($bla) and count($bla).
Optimisations
In the previous section, it was mentioned that you can use different forms (thus functions) in the second parameter 'conditional statement'. Bearing this in mind, the function is called each iteration, thus slowing your procedure down. Therefore, on larger looping structures, consider determining the size of the stop value before the loop or consider using something like below:
Code: [hide]
Code: [show]
for ($i = 0, $size = sizeof($bla); $i < $size; $i++)
{
echo $i;
} In the above code, the size of $size is determined within the function, but still only calculated once.
Summary
To conclude, the for() loop is an iterative function of which we know how many iterations to be executed and carried out by the program code.

Building Blocks of PHP

2009-06-18T20:09:00.000-07:00

Understand the linguistic terms of PHP, including boolean, operators, variables and constants.
Variables
A variable is a special container that you can define, which will then contain a value you specify. For example a number, string, object, array or boolean.
Constants
If you want to work with a value that needs to remain unchanged, you can define and use a constant variable. This isdifferent to a variable as variables offer a flexible way of storing data as you can change their values and type of data they hold.
Globals and Superglobals
In addition to global declerations aof your own, PHP has built in predefined variables called superglobals. These are always present and the value they hold can be available in all your scripts.
Predefined Constants
PHP provides some built in constants for you. For example __FILE__ returns the name of the file that PHP is using. __LINE__ returns the line number that php is running and PHP_VERSION returns what php version your script is being run on.
Data types
Different types of data will take up different amounts of memory and may then be treated different in the script that you write. PHP will automatically determine the data type for the variable the time data is assigned to it. Some examples of data types are boolean, integer, float, string, object, array, resource, null (an uninitialized value).
The Assignment operator
The equals sign (=) is an assignment operator and will put the value on the right hand site and assign it to the left hand side.
Arithmetic Operators
Arithmetic operators perform mathematic operations on the values you want them to (providing they are a number). Some examples are addition (+), subtraction (-), division (/), multiplication (*), modulus (%). You can increment numbers by putting two addition operators nxet to eachother like so: (++). PHP provides combined operators which allow you to transform the left hand operand and return a result, while also modifying the original value of the variable. To return 'x' and and 5 to 'x' on the same line you would use '$x +=5.'
The Concatanation Operator
The concatanation operator allows you to join strings together. It is represented by a single period (.). Expressions, calculations and variables can also be concataned and the data type returned will aloways be that of a string.
The Comparison Operator
Comparison operators perform comparative tests using their operands and return the boolean value true if the test is succesful and false if it false. Some examples are Equivalence (==), Non-equivalence (!=), greater than (>), less than or equal to (<=). You can use logical operators such as Or (), and (&&) and Not (!) to extend comparisons using the if() statement.

How to save a tool with the Tool Preset Palette.

2009-06-16T19:41:00.000-07:00

Before I started working on this, I'd never used the Tool Preset Palette. It was just one of those five thousand pull down menus I was always opening by mistake.
As with many things in Photoshop, there are multiple ways to get to the Tool Preset Palette. Here are two:
(1) A pull down menu "Tool Preset Picker" (TPP)on the left of the Options Bar.
(2) A tab on the History Palette.

It works like this.

Choose the tool and settings you wish to save. In this case I have the Pencil tool, set to 4 pixels, and black.
Click on the little Arrow button in the upper right corner of the TPP or the History Palette, and select “New Tool Preset.”

A window will pop up with a field for naming the preset. If the tool is a brush or pencil, an option is provided for saving the color with the preset. You can accept the name PhotoShop offers, or make up your own. You could use your friend's names, but It's easier to keep track of them if the name is relevant (and some of us don't have that many friends).

When you have finished defining your preset tools, use the TPP menu to Save Tool Presets. I recommend saving your new set under a unique name to distinguish it from your default tool presets. (I named mine after my favorite peripheral, “X-keys”).
So now you too can have a 40 pixel, Color Burn Mode, 42% Opacity, Magenta brush named Maggie in your TPP, but you still have to mouse away from the drawing to open the menu and get the tool, right? Not if you keep going.

Redirection based on browser type

2009-01-08T21:09:00.000-08:00

Intro: This tutorial will teach you how to make a script that will redirect users based on their browser type to different pages or url. It is restricted to two browser types only which are Internet Explorer and Netscape Navigator. You are not going to learn how to write this script, but learn how to use Dreamweaver to make such a script.

1:- First open Dreamweaver and make a new page. Go to Window > Behaviors if your behaviors panel is not open. Then click on the + sign and choose Check Browser

2:-You will be shown this window when you choose the Check Browser Option.

Here you should make your choices, I have chosen here if the Browser is:

Netscapte Navigator 4.0 and later - go to www.yahoo.com and if it is Netscape www.google.com
After you make your selection Click OK

3:-Make sure onLoad option is chosen under the Events, we want users to be redirected when this page loads.

You are done, preview your page and see where you are redirected based on your Browser Type.

4:- You could as well redirect all the users who are using Netscape Navigator to one page and Internet Explorer user to other. This way if you have two versions of you website for specific browser types, you could redirect them to respectie pages which are viewed best by their specific browser types. It is matter of how you use this script.

5:-Another option is redirect all four options to one page, then it would become a normal redirection script that all the users to one specific page.

Here is the code that is generated by Dreamweaver after this tutorial:

How to open a Fixed (size) Window

2009-01-08T21:02:00.000-08:00

1:-Opening a fixed window can be very useful especially if you want a user to see some useful things in that particular window, it can be a photo gallery or Rules & Regulations that you want to display when the user clicks...etc. You can display anything on it and you can specify the size as well, so that the window size corresponds to the content size. Let's get started.

Open a new page in your Dreamweaver and put a button, download the button below for your working purposes or put your own button if you have one ready. Save the page as fixed_window.html

2:-Now click on the button that you have just inserted to the page, and go to Behaviors Panel. If Behaviors Panel is not open go to Window > Behaviors (Shift + F3) to open it. Click on the plus (+) sign and choose Open Browser Window.

3:-Now, you should see a pop-up window, as shown below.

For URL to Display opton you can enter a Web Address or a page name. For the size of the window you can specify the width and height in pixels. I have specified 500 pixels for width and 400 pixels for height. I know it will be a small window for a page like Google so I have ticked the Resize Handlers. This will display Resize Handlers to the user so that he can adjust it. If you don't tick this it will be a fixed size window 500 by 400 which will not be resizable. Other options are pretty understandable, you can just try them if you don't know what are they for

Click OK.

4:-Now you have almost completed your pop-up window, there is one more thing left which is assiging action to your button. You need to specify an action to your button, whether you want a user to click to see the window, or mouse over it...etc. See your Behaviors Panel again and you should see that the action is already specified, in my case it is onMouseOver. If you want to choose any other action just click on the triangle on the right and you will be displayed with other Actions to choose from.

If you want to Edit your window preferences, such as changing the size or url...etc. Just double click on the Open Browser Window word on the right, in Behaviors Panel.

Creating CSS in Dreamweaver MX 2004

2009-01-08T20:15:00.000-08:00

1:- I hope you know the advantages of using CSS instead of tags for your texts and even for your overall website designs. I am not going to discuss that here, if you would like to tknow more on CSS advantages please visit CSS Zen Garden. In this tutorial I will discuss how to create CSS tags in Dreamweaver and apply them to texts.

2:- There are two types of CSS creation, one is to create inside the html page and apply to the same page and another to create it as a separate .css file. If you are working with a single page, then it is better to create CSS inside the page, but if you are working with many pages then it is better to create a separate file because that way you can apply this file to your other pages. That will save you time, you will not have to create it again and again for every page. Later it will save you time in updating your page in case if you want to change the size of your text, you just have to change in one file and all the pages will be updated automatically.
3:- To apply CSS to your current working page, please go to Edit > Preferences > General and tick where it says Use CSS instead of HTML tags and click OK. See below.

Once you make these changes in preferences dreamweaver will apply CSS to your texts whenever you change font size, color, face...etc And it will create CSS codes accordingly under the name style1, style2...etc You can change these names to meaningful words if you want.
4:- To see how it works, open a new page and type some words in the page and change font size or color, and see how it has created a CSS style and applied it to your text. You can see it from properties box as shown below. You can see your CSS styles in your CSS Styles Panel. Go to Window > CSS Styles if the panel is not already open. In CSS Styles Panel you can edit your styles, if you want to edit just right click on your CSS style and choose Edit... and you will be displayed with a pop-up window, where you can specify properties.

5:- We have learned how to create a CSS style inside the page in the previous page, now we will learn how to create a separate CSS file. Open your CSS Styles Panel and click on the New CSS Style button.

6:- You will be shown a new pop-up window like below. Choose a name for your CSS style. For the Selector Type: use Class (can apply to any tag) , and for Define in: use (New Style Sheet File). Press OK.

7:- Give your CSS file a name and Press Save. In step 6 you gave a name to your CSS Style, here you are giving a name to your CSS File. Please note that in one CSS File you can have many CSS Styles, so don't confuse these namings.

8:-Once you press save you will be shown another pop-up window where you define your CSS properties. Please see below. Once you define the properties of your text, Press OK.

After you press OK your new CSS Style will appear in the CSS Styles Panel.

9:-To apply your new CSS Style to any text, just highlight the text and choose your style from Properties Panel.

PHP and Web Design

2008-07-21T05:06:00.000-07:00

1.Open Notepad and type the following as shown below

Save it as header.html

2.Create new file in your notepad and type the following

Save it as main.html

3. Create one more new file and type the following

Save it as footer.html

4. Next we link them together. Open another new file in your notepad

and type the following. This is how the linking in PHP done.

Save it as index.html. All pages should be in the same folder.

Otherwise the linking won't work. Now access the index.html through

your webserver. You should be able to see the following page.

Now change the contents of each page with respective content, I have

tried to make it as simple as possible and not to put so much codes inside

the html, so that you won't get confused. Because once you know how it

is done, you can replace the contents yourself with complicated codes

such as tables, javascript, CSS etc. So if you have 100 pages and you have

to change your Top Menu link, you don't have to go to every page and

change it manually, just change it in header.html and it is done! Good Luck!

Date and Time in PHP
