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:phpStudyPHPTutorialWWWindex.php on line 9 and defined in D:phpStudyPHPTutorialWWWindex.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:phpStudyPHPTutorialWWWindex.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.
