Search the PHP-documentation off-line

Version: 1.0
Type: Full Script
Category: HTML

Description: An ugly hack that searches the php-documentation. The script includes the selected/found file and makes some replacements in it so that the search form is always presented. I guess the official search engine at php.net is better, but since I only have modem access I feel reluctant to connect everytime I need to check the docs :)

An ugly hack that searches the php-documentation. The script includes the selected/

There _are_ bugs in this script, but it workes good enought to be usable.
