   (PHP 3>= 3.0.8, PHP 4 )
   strip_tags -- Strip HTML and PHP tags from a string

Description

   string strip_tags ( string str [, string allowable_tags])

   This function tries to return a string with all HTML and PHP tags
   stripped from a given str. It errors on the side of caution in case of
   incomplete or bogus tags. It uses the same tag stripping state machine
   as the fgetss() function.

   You can use the optional second parameter to specify tags which should
   not be stripped.

     Note: allowable_tags was added in PHP 3.0.13 and PHP 4.0b3.

   Example 1. strip_tags() example
   <?php
   $string = strip_tags($string, '<a><b><i><u>');
   ?>

   Warning

   This function does not modify any attributes on the tags that you
   allow using allowable_tags, including the style and onmouseover
   attributes that a mischievous user may abuse when posting text that
   will be shown to other users.
