note 112391 added to function.mb-detect-encoding

Just a note: Instead of using the often recommended (rather complex) regular expression by W3C (http://www.w3.org/International/questions/qa-forms-utf-8.en.php), you can simply use the 'u' modifier to test a string for UTF-8 validity: <?php if (preg_match("//u", $string)) { // $string is valid UTF-8 } ---- Server IP: 69.147.83.199 Probable Submitter: 67.159.5.242 ---- Manual Page -- http://php.net/manual/en/function.mb-detect-encoding.php Edit -- https://master.php.net/note/edit/112391 Del: integrated -- https://master.php.net/note/delete/112391/integrated Del: useless -- https://master.php.net/note/delete/112391/useless Del: bad code -- https://master.php.net/note/delete/112391/bad+code Del: spam -- https://master.php.net/note/delete/112391/spam Del: non-english -- https://master.php.net/note/delete/112391/non-english Del: in docs -- https://master.php.net/note/delete/112391/in+docs Del: other reasons-- https://master.php.net/note/delete/112391 Reject -- https://master.php.net/note/reject/112391 Search -- https://master.php.net/manage/user-notes.php
