 <para>
  The {php} tags allow PHP code to be embedded directly into the template. They
  will not be escaped, regardless of the <link
  linkend="variable.php.handling">$php_handling</link> setting. This
  is for advanced users only, not normally needed and not recommended.
 </para>
 <example>
  <title>{php} tags</title>
  <programlisting>
<![CDATA[
{php}
   // including a php script directly
   // from the template.
   include('/path/to/display_weather.php');
{/php}
]]>
  </programlisting>

<para>
   To access PHP variables in {php} blocks you may need to use the PHP
   <ulink url="&url.php-manual;global">global</ulink>
   keyword.
</para>
</note>

 <example>
  <title>{php} tags with global and assigning a variable</title>
  <programlisting role="php">
<![CDATA[
{php}
   global $foo, $bar;
   if($foo == $bar){
     echo 'This will come out in the template';
   }
$this->assign('varX','Strawberry');
{/php}
<strong>{$varX}</strong> is my fav ice cream
]]>
  </programlisting>
  <para>The following seriously NOT recommended as its in the template scope</para>
<programlisting 
<![CDATA[
{php}
print_r($some_array);
{/php}
