PHP On scope resolution operator

<?php 
    class a {   

     function fn () {
            echo "My name here";
        }

    }   

a::fn();     
?>

I used scope resolution operator to check how it works, it gave no error when i checked in browser it printed correctly.

But same code when I run nusphere PhpEd debugger tool it gave me error like

Strict Standards: Non-static method a::fn() should not be called statically in D:\Program_Files\wamp\www\test\index.php on line 12 My name here

but it printed the results correctly. May i know what actuall problem is , I am new to PHP classes.I tried in google but i didn't get the reason.

Advance Thanks

The error you're seeing is E_STRICT, which may not be displayed on your server. If you set error_reporting(E_ALL | E_STRICT) you'll probably see that error.

The reason you're seeing the error is that the function fn is not declared static, so you can't necessarily call it statically (like a::fn()). You would call a non-static method like this:

$a = new a();
$a->fn();

To make your function static, change the method declaration:

public static function fn() {
    // ...
}

EDIT: This manual page shows an example similar to yours above.

do you need to call it as a static menthod? why not try: 

$a = new a();
$a->fn();

this should work ^^
