Here's the original code I have:

[PHP] /* Highlight function names in [php] */
$allfuncs = get_defined_functions();
$searches = array();
$replaces = array();
foreach ($allfuncs['internal'] as $name) {
$searches[] = "/([^a-z])$name(<\/font><font color=\"" . ini_get('highlight.keyword') . "\">){0,1}( {0,1})\(<\/font>/i";

above it with some more code. What do I need to replace?

put at the end of functions.php before the ending ?> :)

Well, that got rid of the error, but still no links in the php code. ;)

perhaps a link to the part where you edit this option would be handy since i can't find it..

it's in the user options :)
