Introduction to Server Scripting language Client VS Server Introduction to PHP PHP Files and Syntax Function of PHP Why PHP? Implementing PHP How PHPWorks? Requirements for PHP How to write PHP codes

Slide 3

Students will design and develop webpage using Server-Side scripting for efficient user interaction. Students will establish, configure and maintain an intranet and internet website. Students will understand about PHP, requirement and function of PHP.

Slide 4

Slide 5

In a client-server application there are two kinds of scripts or program: client-side script client side script like Client-JavaScript is run on the client computer using web browser. server-side script server-side script like ASP,PHP, and ColdFusion is run by Web server (such as IIS Apache, etc.)

Slide 6

Reduce requests needed to be passed to server Access browser Enhance Web pages with DHTML, ActiveX controls, and applets Validate user input Executed on server Generate custom response for client Wide range of programmatic capabilities Access to server-side software that extends server functionality

Slide 7

Faster to display since workload is distributed to users PC Customizable output personalized experience Cannot retain global data Cannot store data from user into database

Slide 8

Data from user can be stored into database Web server control users browsing selection The processing is centralized at the server. This will put the burden of processing on the server instead of the client

Slide 9

PHP To have basic understanding of HTML, CSS and JavaScript PHP stands for Hypertext Preprocessor PHP is a widely-used, open source scripting language PHP scripts are executed on the server PHP is open source software and it is FREE Current version of PHP is Version 6.

Slide 10

PHP files can contain text, HTML, CSS, JavaScript, and PHP code PHP code are executed on the server, and the result is returned to the browser as plain HTML PHP files have extension *.php In terms of keywords and language syntax, PHP is similar to most high level languages that follow the C style syntax. if conditions, for and while loops, and function returns are similar in syntax to languages such as C, C++, C#, Java and Perl.

Slide 13

To implement PHP, you need a SERVER inside your computer It is FREE! Server is used to test PHP script in your computer. PHP code is interpreted by a web server with a PHP processor module, which generates the resulting web page. PHP commands can be embedded directly into an HTML source document rather than calling an external file to process data

Slide 14

PHP code is interpreted by a web server with a PHP processor module, which generates the resulting web page: PHP commands can be embedded directly into an HTML source document rather than calling an external file to process data. PHP Scripts Web browser PHP Module Web Server (XAMPP) Send script Return output

Slide 15

Install a web server Eg. XAMPP Install PHP Eg. phpMyAdmin Install a database, such as MySQL

Slide 16

Install PHP MyAdmin for database & coding platform http://www.phpmyadmin.net/home_page/index.php http://www.phpmyadmin.net/home_page/index.php Look & try at the Demo first before download the software. Install XAMPP for server http://www.wikihow.com/Install-XAMPP-for-Windows http://www.wikihow.com/Install-XAMPP-for-Windows
