I was kind of hoping to find a function where I can swap values in a string, but I couldn't find one, so I wrote one, here it is

<?php
function str_swap($swp1,$swp2,$str)

                                 {

                                 srand ((double) microtime() * 1000000);

                                 for($i=0;$i<32;$i++) $tmp .= rand(0,9);

                                 str_replace($swp1,$tmp.$swp1.$tmp,$str);

                                 str_replace($swp2,$swp1,$str);

                                 str_replace($tmp.$swp1.$tmp,$swp2,$str);

                                 return $str;

                                 }
?>

Usage Example

$string = 'Bob went out with Sally.'; 

                            echo str_swap('Bob','Sally',$string);

                            

                            RESULT:

                            Sally went out with Bob.
