List functions disabled in PHP

I've got a web client having some really odd problems with a program of mine logging him out randomly. Normally I upload a phpinfo file and use that to see if I could find out anything but when I did that I got an error that phpinfo had been disabled for "security purposes".

What I really needed was a list of what other functions have been disabled, so I put together the little script below to pull the list of disabled functions, sort them, and then echo them out. Of course if ini_get has been disabled then I might be in trouble and have to actually ask the host for the list.

PLAIN TEXT
PHP:
  1. <?php
  3. $disabled_functions = ini_get('disable_functions');
  4. if ($disabled_functions!='')
  5. {
  6. $arr = explode(',', $disabled_functions);
  7. sort($arr);
  8. echo 'Disabled Functions:
  9. ';
  10. for ($i=0; $i
  11. {
  12. echo $i.' - '.$arr[$i].'<br>';
  13. }
  14. }
  15. else
  16. {
  17. echo 'No functions disabled';
  18. }
  19. ?>
