User "a dot lyskawa at pp-layouts dot com" made a few mistakes in mb_str_ireplace()
function.
First of all there is no such function like ok(). I guess it should look like:
<?
function ok($var) {
return ($var!==false);
}
?>
There is no predefined constans like 'u8', str_ireplace trades count parameter as count of
replacements and in function is unused variable $rc.
I think that most of these mistakes was made wne function was taken from the users' "MB
Class".
I made some improvements too. Most of all we need str_ireplace to prevent case of replecement
according to case of found search. So better mb_str_ireplace function should look like:
<?
function mb_str_ireplace($search, $replace, $subject, &$count = null, $encoding =
'UTF8') {
$count = 0;
$l1 = mb_strlen($search, $encoding);
$l2 = mb_strlen($replace, $encoding);
$rc = 0;
$offset = 0;
while(ok($p = mb_stripos($subject, $search, $offset, $encoding))) {
if (ok($p)) {
$found = mb_substr($subject, $p, $l1, $encoding);
$offset2 = 0;
while (ok($pp = mb_stripos($replace, $found, $offset2, $encoding))) {
for ($i=0; $i<mb_strlen($found, $encoding); $i++) {
$ls = mb_substr($found, $i, 1, $encoding);
$lr = mb_substr($replace, $pp+$i, 1, $encoding);
$lr = (ctype_lower($ls)?mb_strtolower($lr):mb_strtoupper($lr));
$replace = mb_substr($replace, 0, $pp+$i, $encoding) . $lr . mb_substr($replace, $pp+$i+1,
mb_strlen($replace, $encoding), $encoding);
}
$offset2 = $pp + mb_strlen($found, $encoding);;
}
$subject = mb_substr($subject, 0, $p, $encoding) . $replace . mb_substr($subject, $p + $l1,
mb_strlen($subject, $encoding), $encoding);
}
$offset = $p + $l2;
$rc++;
$count++;
}
return $subject;
}
?>
