I've looked just about EVERYWHERE to try to find this, Google searched, looked all through the PHP Manual, and nothing has given me the answer to it.

So I am trying to use the following example preg_replace and I'm not sure as to what '/u`' is :

$string = preg_replace(array("/\\$replace/u"), array('something'), $string);

But I'm not sure as to what searching for u actually does for my output.

I know that i means that the string isn't going to be searched case sensitively, and was thinking that u does the opposite?

A hint: php.net contains all the necessary information on regex modifiers. – Wiktor Stribiżew May 11 '16 at 06:53

These suffixes are called pattern modifiers, they are listed here: http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php – Tyron May 11 '16 at 11:03
