在PHP中引用函数的最佳方法是什么？

Let's say I can call a method like this: core::get(). What is the best way to reference to this method? Everytime I call a function called get it should call core::get() and pass the same parameters.

All I could come up with was this:

function get(){
    call_user_func_array('core::get', func_get_args());
}

But it doesn't look very elegant if I compare it to the way I'd solve this in JavaScript:

var get = core.get;

I'm sure I missed something in PHP, so does anybody has a better solution for this?

This is almost equivalent to your solution that already looks good:

$get = function () {
  call_user_func_array('core::get', func_get_args());
};

//usage

$get('arg1','arg2');

Note in the case you got a simple function you have could do this:

function foo() {} 
$var = 'foo';
$var();  //> same as calling foo();
