A comprehensive guide for the PHP scripting language.
PHP-enabled web pages are handled the same as regular HTML pages. The server must provide active support for php and all PHP files must end with .php as an extension.
PHP code can be imbedded in html pages and executed when the page is opened. PHP commands must be enclosed within special start and
<?php Script goes here ?>
<? Script goes here ?>
To check the php configuration settings on your server, the following phpinfo() function can be called from within a php enabled web page.
<?php phpinfo(); ?>
Php files must be saved as plain text. For a list of text editors that work well for php, check the list available at Wikipedia, and for more complete tutorials of the PHP scripting language, check the resources below.
