If we have it, then we don't have to worry about string callback functions. if (in_array(function($elem) {return is_numeric(strstr($elem));}, $array)) { ... } Why don't we have 'closure' as signature? It can do more than calling a function. bool in_array(closure $callback, array $ary); Cons would be we cannot search closures in $ary. Is there any use of searching closure?
