PHP Object Issues

I wrote a class, like class MyClass,
Then I am in one of the pages such as a.php, I instantiate $obj 1=new MyClass ();
$obj1 can I use this instantiated object to be referenced by other pages? It's definitely not possible. So if I want to refer to the b.php page, do I need to instantiate it in a different format? It is not very troublesome ....

Reply to discussion (solution)

Class MyClass writes the method of this class as a static method so that it can be used directly on each page.
such as: Myclass::func ();

Also need to include this class file

 
 A (); #b. Php//include Function.phpecho test::instance ()->b ();

Forget the static class this stuff. Thank you!
