note 73697 added to function.preg-replace

I could not find a function to unescape javascript unicode escapes anywhere (e.g., "\u003c"=>"<"). <?php function js_uni_decode($s) { return preg_replace('/\\\u([0-9a-f]{4})/ie', "chr(hexdec('\\1'))", $s); } echo js_uni_decode("\u003c"); ?> Solution adapted from http://weierophinney.net/matthew/archives/ 133-PHP-decoding-of-Javascript-encodeURIComponent-values.html ---- Server IP: 61.195.146.164 Probable Submitter: 220.220.126.30 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- https://master.php.net/note/edit/73697 Del: integrated -- https://master.php.net/note/delete/73697/integrated Del: useless -- https://master.php.net/note/delete/73697/useless Del: bad code -- https://master.php.net/note/delete/73697/bad+code Del: spam -- https://master.php.net/note/delete/73697/spam Del: non-english -- https://master.php.net/note/delete/73697/non-english Del: in docs -- https://master.php.net/note/delete/73697/in+docs Del: other reasons-- https://master.php.net/note/delete/73697 Reject -- https://master.php.net/note/reject/73697 Search -- https://master.php.net/manage/user-notes.php
