Comparison of exception and error handling in PHP7 with previous versions

First code

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;
Copy after login

PHP v5.6.1 result
