Need some help diagnosing functions_general,php errors

[Design75]

I had one last idea before shutting down

// bof dynamic filter 1 of 3
        if ( (!in_array($key, $exclude_array)) && (strlen((int)$value) > 0 || is_array($value) && array_filter($value) ) && ($key != 'main_page') && ($key != zen_session_name()) && ($key != 'error') && ($key != 'x') && ($key != 'y') ) {
// eof dynamic filter 1 of 3 

I added (int) to the strlen and it seems to do the job, but I am no expert.

p.s. I wasn't getting any errors at first because I made some other stupid mistake. after fixing that the errors started coming in until I added the int
