PHP7中异常与错误处理与之前版本对比

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 v5.6.27结果

 5.6.27

 Catchable fatal error: Argument 1 passed to add() must be an instance of int, string given, called in D:\phpStudy\PHPTutorial\WWW\index.php on line 9 and defined in D:\phpStudy\PHPTutorial\WWW\index.php on line 3

PHP v7.0.12结果

 7.0.12
 string(127) "Argument 1 passed to add() must be of the type integer, string given, called in D:\phpStudy\PHPTutorial\WWW\index.php on line 9"
 helloword

区别

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