The <varname>{php}</varname> tags allow PHP code to be embedded directly into the template. They
|
|
will not be escaped, regardless of the <link
|
|
linkend="variable.php.handling"><parameter>$php_handling</parameter></link> setting. This
|
|
is for advanced users only, not normally needed and not recommended.

To access PHP variables in <varname>{php}</varname> blocks you will need to use the PHP

<ulink url="&url.php-manual;global">global</ulink>
|

keyword.
