Some general advice:

1. It's difficult to troubleshoot this kind of problem without the error message. If no error is being printed where you can see it, look for files named php.log, error.log, or httpd.log or ask your server admin(s).

2. Try using print_r() on your arrays to see if there's any difference in how they're structured. For example, just after setting the arrays in PHP:

   print_r($fileArray);
   print_r($listTextArray);
   print_r($falseArray);
   

3. Rather than constructing the JS arrays via loops, try using the built-in json_encode() function instead. This both simplifies your PHP code and may cause more useful error messages when there are problems:

   var filesArray=;
   var falseArray=;
   var textListArray=;
