Test script: --------------- var_dump(readdir(false)); //Will return // Warning: readdir() expects parameter 1 to be resource, boolean given in /..../test.php on line 11 // /..../test.php:11:null while (false !== ($logFile = readdir(false))) { var_dump($logFile); } // Will put your process an infinitive loop ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75136&edit=1
