regex - Convert spaces of all sizes to a standard space in PHP? -

was wondering if there clean way replace space character variants (half space, full-width space, chinese space, etc.) standard space?

bonus points replacing multiple spaces in row (like 3 half-width or zero-width spaces or of each) single normal space.

preg_replace('~\s+~u', ' ', 'your    input   here');

see http://php.net/manual/en/function.preg-replace.php
