note 57339 added to function.utf8-decode

In response to fhoech (22-Sep-2005 11:55), I just tried a simultaneous test with the file UTF-8-test.txt using your regexp, 'j dot dittmer' (20-Sep-2005 06:30) regexp (message #56962), php-note-2005 (17-Feb-2005 08:57) regexp in his message on mb-detect-encoding page (http://us3.php.net/manual/en/function.mb-detect-encoding.php#50087) who is using a regexp from the W3C (http://w3.org/International/questions/qa-forms-utf-8.html), and PHP mb_detect_encoding function. Here are a summarize of the results : 201 lines are valid UTF8 strings using phpnote regexp 203 lines are valid UTF8 strings using j.dittmer regexp 200 lines are valid UTF8 strings using fhoech regexp 239 lines are valid UTF8 strings using using mb_detect_encoding Here are the lines with differences (left to right, phpnote, j.dittmer and fhoech) : Line #70 : NOT UTF8|IS UTF8!|IS UTF8! :2.1.1 1 byte (U-00000000): "" Line #79 : NOT UTF8|IS UTF8!|IS UTF8! :2.2.1 1 byte (U-0000007F): "" Line #81 : IS UTF8!|IS UTF8!|NOT UTF8 :2.2.3 3 bytes (U-0000FFFF): "" | Line #267 : IS UTF8!|IS UTF8!|NOT UTF8 :5.3.1 U+FFFE = ef bf be = "" | Line #268 : IS UTF8!|IS UTF8!|NOT UTF8 :5.3.2 U+FFFF = ef bf bf = "" | Interesting is that you said that your regexp corrected j.dittmer regexp that failed on 5.3 section, but it my test I have the opposite result ?! I ran this test on windows XP with PHP 4.3.11dev. Maybe these differences come from operating system, or PHP version. For mb_detect_encoding I used the command : mb_detect_encoding($line, 'UTF-8, ISO-8859-1, ASCII'); ---- Manual Page -- http://www.php.net/manual/en/function.utf8-decode.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57339 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57339&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57339&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57339&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57339&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57339&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57339&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57339&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57339&report=yes Search -- http://master.php.net/manage/user-notes.php
