PHP7中異常與錯(cuò)誤處理與之前版本對(duì)比

先上代碼
ECHO PHP_VERSION.PHP_EOL;
function add (int $left,int $right){
return $left+$right;
}
try {
echo add('left', 'right');
} catch (Exception $e) {
// Handle exception
} catch (Error $e) { // Clearly a different type of object
// Log error and end gracefully
var_dump($e->getMessage());
}
echo PHP_EOL."helloword".PHP_EOL;PHP v5.6.1結(jié)果
5.6.1 PHP Catchable fatal error: Argument 1 passed to add() must be an instance of int, string given, called in C:\usertb\shareubuntu\Workerman\fortest.php on line 8 and defined in C:\usertb\shareubuntu\Workerman\fortest.php on line 3 Catchable fatal error: Argument 1 passed to add() must be an instance of int, string given, called in C:\usertb\shareubuntu\Workerman\fortest.php on line 8 and defined in C:\usertb\shareubuntu\Workerman\fortest.php on line 3 [Finished in 0.0s]
PHP v7.0.15結(jié)果
7.0.15-0ubuntu0.16.04.4 string(131) "Argument 1 passed to add() must be of the type integer, string given, called in /home/tb/win10share/Workerman/fortest.php on line 8" helloword
區(qū)別
在于后者可以捕獲fatal error,并且可以正常輸出helloword
