PHP7中異常與錯誤處理與之前版本對比

先上程式碼

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結果

5.6.1

PHP v7.0.15結果

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

區別

在於後者可以捕獲fatal error，並且可以正常輸出helloword
