I found that this approach is often faster than strtr() and won't change the same thing in your
string twice (as opposed to str_replace(), which will overwrite things in the order of the array you
feed it with):
<?php
function replace ($text, $replace) {
$keys = array_keys($replace);
$length = array_combine($keys, array_map('strlen', $keys));
arsort($length);
$array[] = $text;
$count = 1;
reset($length);
while ($key = key($length)) {
if (strpos($text, $key) !== false) {
for ($i = 0; $i < $count; $i += 2) {
if (($pos = strpos($array[$i], $key)) === false) continue;
array_splice($array, $i, 1, array(substr($array[$i], 0, $pos), $replace[$key],
substr($array[$i], $pos + strlen($key))));
$count += 2;
}
}
next($length);
}
return implode($array);
}
?>
