note 5984 modified in readfile by ronabop

You might want to try checking the $php_errormsg variable after calling readfile(...). To supress errormessages to your client's browser you could also add @ before readfile(...). Make sure you have track_errors enabled in your php configuration. See: http://www.php.net/manual/language.operators.errorcontrol.php http://www.php.net/manual/function.readfile.php
