Can a method be used as an array_map function

Question

I want to do something like this:

 class Cls {   function fun($php) {     return 'The rain in Spain.';   } }  $ar = array(1,2,3); $instance = new Cls(); print_r(array_map('$instance->fun', $ar));                // ^ this won't work 

but the first argument to array_map is supposed to be the name of the function. I want to avoid writing a wrapper function around $instance->fun, but it doesn't seem like that's possible. Is that true?

Answer 1

Yes, you can have callbacks to methods, like this:

array_map(array($instance, 'fun'), $ar) 

see the callback type in PHP's manual for more info

Answer 2

You can also use

array_map('Class::method', $array)  

syntax.
