$string = \"Good one :y. Keep going :y2\"; 

         


        

Answer 1

Try to replace first for :y2 and then for :y

$string = "Good one :y. Keep going :y2"; 

$my_array= array(":y2" => "b", ":y" => "a");

$str = str_replace(array_keys($my_array), array_values($my_array), $string);

outputs

Good one a. Keep going b
