note 103860 added to function.iconv

A simple cleaning function [eg: iconv("UTF-8","UTF-8//IGNORE", $s)] may not be enough when receiving UTF8 input that needs to be saved in MySQL. Prior to MySQL v5.5 four byte sequences were not supported so a function is needed to strip these out as well: <?php for($pos=strlen($strUtf8)-1; $pos >= 0 ; $pos--){ $char = substr($strUtf8, $pos, 1); if (ord($char) > 0xEF) $strUtf8 = substr($strUtf8, 0, $pos).substr($strUtf8, $pos+1); } ?> ---- Server IP: 222.73.207.145 Probable Submitter: 127.0.0.1 (proxied: 124.78.36.153) ---- Manual Page -- http://www.php.net/manual/en/function.iconv.php Edit -- https://master.php.net/note/edit/103860 Del: integrated -- https://master.php.net/note/delete/103860/integrated Del: useless -- https://master.php.net/note/delete/103860/useless Del: bad code -- https://master.php.net/note/delete/103860/bad+code Del: spam -- https://master.php.net/note/delete/103860/spam Del: non-english -- https://master.php.net/note/delete/103860/non-english Del: in docs -- https://master.php.net/note/delete/103860/in+docs Del: other reasons-- https://master.php.net/note/delete/103860 Reject -- https://master.php.net/note/reject/103860 Search -- https://master.php.net/manage/user-notes.php
