note 39932 added to function.utf8-encode

Here is a simple function that can help, if you want to know if a string could be UTF-8 or not : <?php function seems_utf8($Str) { for ($i=0; $i<strlen($Str); $i++) { if (ord($Str[$i]) < 0x80) $n=0; # 0bbbbbbb elseif ((ord($Str[$i]) & 0xE0) == 0xC0) $n=1; # 110bbbbb elseif ((ord($Str[$i]) & 0xF0) == 0xE0) $n=2; # 1110bbbb elseif ((ord($Str[$i]) & 0xF0) == 0xF0) $n=3; # 1111bbbb else return false; # Does not match any model for ($j=0; $j<$n; $j++) { # n octets that match 10bbbbbb follow ? if ((++$i == strlen($Str)) || ((ord($Str[$i]) & 0xC0) != 0x80)) return false; } } return true; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.utf8-encode.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39932 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39932&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39932&report=yes Search -- http://master.php.net/manage/user-notes.php
