How to use array_map with a function that takes more than one parameter?

Question

I have an array that contains string that have underscores or _ in them, I need to replace the underscores with spaces using str_replace and I want to do it using array_map()

array_map can take function that only have one parameter in them but str_replace takes three parameters:

1. What to replace
2. Replace it with what
3. String

I can perfectly use a foreach loop to do the following but I was wondering how would I be able to do it with array_map. I did some looking on google and in stackoverflow but I couldn't find a solution.

Here's an example of the array that I have

$array = array("12_3","a_bc");

You can try like this

<?php
function replace($array)
{
    $replace_res = str_replace('_', ' ', $array);
    return  $replace_res;
}

$array = array("12_3","a_bc");
$result = array_map("replace", $array);
print_r($result);
?>
