Question

In Javascript there is call() and apply(), that partially, but resolves to call_user_func() and call_user_func_array() in PHP.

Now, the difference here is that we can pass a variable with call() and apply() to be used as this within the function scope.

Can I achieve something like this with PHP?

Update:

In Javascript:

var x = function(passed)
{
    return { dis : this, passd : passed };
};

console.log(x(44)); // window, 44

console.log(x.call(25, 44)); // 25, 44

.call() first parameter within the function scope, becomes this.

From the PHP manual for Callbacks:

A method of an instantiated object is passed as an array containing an object at index 0 and the method name at index 1.

Example below:

// Type 3: Object method call
$obj = new MyClass();
call_user_func(array($obj, 'myCallbackMethod'));
