Reproduce code: --------------- // tried both: $fp = fopen('file.ext', "r"); $ctx = hash_init('sha512'); while (!feof($fp)) { hash_update($ctx, fgets($fp,$bytes)); } $res_hash = hash_final($ctx); // this would be line 58 fclose($fp); // and hash_file('sha512', 'file.ext'); // this would be line 67 // $bytes were set to anywhere from 4kB to 32MB.. same result all the time Expected result: ---------------- obviously, a hash. Actual result: -------------- Fatal error: Maximum execution time of 1800 seconds exceeded in /opt/apache/htdocs/hashtest.php on line 58. or Fatal error: Maximum execution time of 1800 seconds exceeded in /opt/apache/htdocs/hashtest.php on line 67. depending what piece of code was commented. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38950&edit=1
