php - Closure with parameter inside array -

i have problem closure in php 5.4

i have array

public function check(){ return ['int'=>['filter'=>2], 'min'=>function($val){ return ['int'=>2,'min'=>$val]; } ] } 

when use

(new obj())->check()['int']; 

it works. don't know how use min parameter example 3

i tryed

(new obj())->check()['min'](3); (new obj())->check()['min'(3)]; (new obj())->check()['min(3)']; 

don't work.

php's parser not task, can't write expression have in other languages. have use workaround, example:

call_user_func((new obj())->check()['min'], 3)); 

or alternatively:

$f = (new obj())->check()['min']; $f(3);
