If they can stay the same capital all over:
$updatedstringwithreplacements = str_replace('X',chr(rand(65,90)),$string);


For a different (or random, zo it could be the same) capital:
<?php
function return_capital(){
return chr(rand(65,90));
}
$string = "aslkXdjfhdsaf;ljnXg;afjafhX;alskjdf;iasdXhfjkaXsXXXdf;kaXXsfda";
$updatedstringwithreplacements =
preg_replace_callback('/X/','return_capital',$string);
?>
