note 95962 added to function.mb-detect-encoding

I was in the need of a function capable of detecting whether a string was ISO-8859-1 compatible or not. Unfortunately I was unable to get mb_detect_encoding to work. The following function does the trick. function IsLatin1($str) { return (preg_match("/^[\\x00-\\xFF]*$/u", $str) === 1); } var_dump(IsLatin1("abc ABC 123")); // true var_dump(IsLatin1("abc € 123")); // false (because of €) ---- Server IP: 87.54.44.10 Probable Submitter: 85.80.149.13 ---- Manual Page -- http://www.php.net/manual/en/function.mb-detect-encoding.php Edit -- https://master.php.net/note/edit/95962 Del: integrated -- https://master.php.net/note/delete/95962/integrated Del: useless -- https://master.php.net/note/delete/95962/useless Del: bad code -- https://master.php.net/note/delete/95962/bad+code Del: spam -- https://master.php.net/note/delete/95962/spam Del: non-english -- https://master.php.net/note/delete/95962/non-english Del: in docs -- https://master.php.net/note/delete/95962/in+docs Del: other reasons-- https://master.php.net/note/delete/95962 Reject -- https://master.php.net/note/reject/95962 Search -- https://master.php.net/manage/user-notes.php
