PHP: Invoke static method without class name

Question

I have simllar question like here: static-method-invocation, but in PHP. Simply, I want have class like this:

static class ClassName{
   static public function methodName(){
         //blah blah blah
   }
}

and I want to call member method without name od class like this:

require_once(ClassName.php);

methodName();

Is it possible in PHP? Thanks for your answers!

You can not do what you're looking for. The example call you give:

methodName();

Is calling a global function. Even static class functions are global as well, they always need the class-name to be called:

ClassName::methodName();

This calls the global static class function you've created in the include file.

I can only guess what you'd like to achieve, maybe you can benefit from the feature that includes can return values:

static class ClassName{
   static public function methodName(){
         //blah blah blah
   }
}
return 'ClassName';

Including:

$className = require_once(ClassName.php);
$className::methodName();

However this won't work with reguire_once when the file has been loaded earlier.

You can write a wrapper function to require_once files, store their return value into a global context array that keeps these values based on the file-name of the include.

Keep in mind that the java language differs from PHP. The equivalent to the java static function would be the global function in PHP:

function methodName(){
    //blah blah blah
}

Including:

require_once(ClassName.php);
methodName();

That's the PHP equivalent.
