PHP Xindice Toolkit

In the PHP Manual, I found the documentation of array_key_exists, and it says:

> array_key_exists
>
> (PHP 4 >= 4.1.0)
...
> Note: The name of this function is key_exists() in PHP version 4.0.6.

So maybe we'll both need to upgrade or do this ;-)

perl -p -i -e 's/array_key_exists/key_exists/' *.php
