php replace all occurances of key from array in string

Question

maybe this is duplicate but i did't find good solution.

I have array

$list = Array
(
   [hi] => 0
   [man] => 1
);
$string="hi man, how are you? man is here. hi again."

It should produce $final_string = "0 1, how are you? 1 is here. 0 again."

How can I achieve it with smart way? Many thanks.

Off of the top of my head:

$find       = array_keys($list);
$replace    = array_values($list);
$new_string = str_ireplace($find, $replace, $string);
