Note Submitter: arne at bukkie dot nl ---- An addition to administrator at proxy-list dot org snippet below. To prevent unnecessary waiting check if the lock is obtained, if so skip the usleep(): $fp = fopen($logFileName, 'a'); $canWrite = false; //Waiting until file will be locked for writing while (!$canWrite) { $canWrite = flock($fp, LOCK_EX); // If lock not obtained sleep for 0 - 2000 miliseconds, to avoid colision if( !$canWrite ) { $miliSeconds = rand(0, 20); //1 u = 100 miliseconds usleep(round($miliSeconds*100000)); } } //file was locked so now we can store information fwrite($fp, $toSave); fclose($fp);
