Description of the Issue

I'm playing with the Function List sidebar for the first time today, and noticed with a PHP file some names are just wrong.

Steps to Reproduce the Issue

1. Retrieve and open https://sourceforge.net/p/xmb-forum/code/2841/tree/xmb19x/trunk/source/include/validate.inc.php?format=raw
2. Click the Function List button on the toolbar.
3. Compare names in sidebar with names in source.

Expected Behavior

The Function List sidebar should simply list the functions defined by the PHP source.

Actual Behavior

Five of the functions near the end of the file are displayed with the wrong names (looks like some chars missing?) in the sidebar.
