Yes, I agree; another solution is as follows:
function alt_str_replace($search, $replace, $subject) {
// Temporary copies of search string and subject string;
// both shifted to lowercase to make the search case insensitive.
$t_search = strtolower($search);
$t_subject = strtolower($subject);
// Initialize result string
$res = "";
// Initialize search vars
$search_offs = 0;
$shift = strlen($search);
// As long as another match is found...
while (($t = strpos($t_subject, $t_search, $search_offs)) !== false) {
// Copy non-matching portion of string
$res .= substr($subject, $search_offs, $t-$search_offs);
// Add replacement value
$res .= $replace;
// Update search offset
$search_offs = $t + $shift;
}
// Add trailing end of string
$res .= substr($subject, $search_offs);
return $res;
}
Hope that helps...
