PHP on UISacad
PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. PHP is a tool that lets you create dynamic web pages. PHP-enabled web pages are treated just like regular HTML pages and you can create and edit them the same way you normally create regular HTML pages.
What do I need?
Just create your .php files and put them in your web directory and the server will magically parse them for you. There is no need to compile anything nor do you need to install any extra tools. Think of these PHP-enabled files as simple HTML files with a whole new family of magical tags that let you do all sorts of things.
Your first PHP-enabled page
Create a file named hello.php and in it put the following lines:
<?php echo “Hello World<p>”; ?>
The colors you see are just a visual aid to make it easier to see the PHP tags and the different parts of a PHP expression. Note also that this is not like a CGI script. The file does not need to be executable or special in any way. Think of it as a normal HTML file which happens to have a set of special tags available to you that do a lot of interesting things.
This program is extremely simple and you really didn’t need to use PHP to create a page like this. All it does is display: Hello World
The point of the example is to show the special PHP tag format. In this example we used <?php to indicate the start of a PHP tag. Then we put the PHP statement and left PHP mode by adding the closing tag, ?>. You may jump in and out of PHP mode in an HTML file like this all you want.
