storing php objects on html form element and passing php objects through GET method?

Question

I might sound a bit weird but, is there a way? For example, I have a PHP object $foo.

Is there a way to store this object in an HTML form (hidden input)

Answer 1

You can use the serialize and unserialize methods:

$serialized = serialize($foo);

Now you can store $serialized in your hidden input field. Later, you can read it back and convert to object with unserialize method. For example:

$foo = unserialize($_POST['my_hidden_field']); // back to object
