Frequently Asked Questions

Do I have to wrap the PHP code in special tags?
No, you can use the regular PHP tags directly. eg:

<?php phpinfo(); ?>

Can I use predefined Joomla variables? Yes, but you first have to declare them as globals. eg:

global $mainframe;

Can I include PHP files? Yes, but make sure you use the full path to the PHP files. It's just easier.
Example: Joomla1.0

global $mainframe;   
include($mainrame->getCfg('absolute_path').'/modules/mod_php/includes/my_php_file.php');

Example: Joomla1.5

include(JPATH_ROOT.'/modules/mod_php/includes/my_php_file.php');

Can I use PHP Component in a module position? No, but we have a module that does this called the Joomla PHP Module.
