Trim unicode whitespace in PHP 5.2

Question

How can I trim a string(6) \" page\", where the first whitespace is a 0xc2a0 non-breaking space?

I\'ve tried trim() and preg_match(\'

Answer 1

however here is my ONLY solution, because sometimes there are UTF8 spaces:

$stringg = preg_replace('/^[\pZ\pC]+|[\pZ\pC]+$/u','',$stringg);
$stringg = preg_replace('/\s+/u', '', $stringg);
