PHP
PHP stands for "Hypertext Preprocessor". PHP is a powerful and free server-side scripting language and is used to create dynamic and interactive websites. Much of its syntax is borrowed from C, Java and Perl but it also has some unique features.
PHP code is enclosed with special PHP tags: <?php ?> and can be imbedded in a HTML page. When the page is opened, the server processes the PHP code and sends the results of the PHP code to the visitor's browser. The visitor cannot see the PHP code so the PHP scripts cannot be stolen or at least it is harder to copy them.
PHP connects to many databases including MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, and Generic ODBC. UNIX servers or web hosting usuallyl offers PHP-MySQL combination and both are open-source, free products.
PHP contains functions to connect to remote servers, check email via POP3 or IMAP, url encoding, set cookies, redirecting, etc.
Learning PHP
PHP code looks like this:
<html>
<head>
<title>Example</title>
</head>
<body>
<h1><?php echo "PHP Example"; ?></h1>
<?php
/***************************
* This is an example of a PHP script.
******************************/
$name = "Jeanie"; //This line assigns a value to a variable.
echo "<p>My name is $name.</p>";
?>
</body>
</html>
