What Is PHP?
PHP (Hypertext Preprocessor) is a server-side, HTML embedded scripting language used to create dynamic Web pages on a Unix based platform.
In an HTML document, PHP script is enclosed within special PHP tags. Because PHP is embedded within tags, the author can jump between HTML and PHP instead of having to rely on heavy amounts of code to output HTML. PHP is executed on the server.
PHP's strength lies in its compatibility with many types of databases. PHP can talk across networks using IMAP, SNMP, NNTP, POP3, or HTTP.
A simple PHP-Script looks like this:
<html>
<head>
<title>My first PHP-Script</title>
</head>
<body>
<?php
echo "Hello World";
echo "Today is ".date("d.m.Y");
?>
</body>
</html>
The output for this is:
Hello World
Today is <current date>
