php-5.3

问题 I have a simple question. I know that I can prevent a form to re-submit itself when the user reloads the page by using the Post/Redirect/Get Pattern.

Any help please Thank you 回答1: yes, but you have to remember to redirect him without the GET params. so you can header('Location: same_page.php?status=done'); die();

So this is the desired behaviour: $x=5;//arbitrary non-object $obj=new Foo; //arbitrary object $collection=new Collection; $collection->add($obj); //should be acceptable arg, no matter the actual class $collection->add($x); //should throw an error because $x is not an object According to the PHP manual, one can typehint methods by prefacing the $arg with a class name. Since all PHP classes are
