If you have a callback that is going to be invoked often, you can use this method (and the related method for ReflectProperty) to get a closure that will execute at near native speed.

Some benchmark comparisons with php 5.4.22 on ubuntu:

[function call]      [time]     [%slower]
function():          0.09527      0%

$string():           0.102641     8%
Reflection:          0.197122   107%
call_user_func:      0.214045   125%

[method call]        [time]  [% slower] [%vs func]
->method():          0.103611    0%       9%
Reflection::Closure: 0.1043      1%       9%
