run code in 300+ PHP versions simultaneously
<?php $a = json_encode('wrong json'); /*if ('50500' <= PHP_VERSION_ID) { var_dump(json_last_error_msg()); }*/ switch (json_last_error()) { case JSON_ERROR_DEPTH: $error = 'Maximum stack depth exceeded'; break; case JSON_ERROR_STATE_MISMATCH: $error = 'Underflow or the modes mismatch'; break; case JSON_ERROR_CTRL_CHAR: $error = 'Unexpected control character found'; break; case JSON_ERROR_SYNTAX: $error = 'Syntax error, malformed JSON'; break; case JSON_ERROR_UTF8: $error = 'Malformed UTF-8 characters, possibly incorrectly encoded'; break; default: $error = 'Unknown error'; break; } var_dump($error);

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
