'/temp/'; mkdir($temp_folder); chmod($temp_folder, 0555); $tmp_name = str_replace("\\", '/', tempnam($temp_folder, 'rhcsv')); $fp = fopen($tmp_name, 'wb+'); if($fp) { flock($fp, LOCK_EX); fwrite($fp, 'test'); flock($fp, LOCK_UN); fclose($fp); } ?> Expected result: ---------------- error message that $dir is not writeable Actual result: -------------- temporary file is created in /tmp which violates open_basedir and fopen() is failing with open_basedir restriction messages ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55804&edit=1
