PHP7中异常与错误处理与之前版本对比

先上代码

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结果

5.6.1PHP 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 3Catchable 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结果

7.0.15-0ubuntu0.16.04.4string(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

区别

在于后者可以捕获fatal error，并且可以正常输出helloword
