note 119137 added to function.iconv

I just found out today that the Windows and *NIX versions of PHP use different iconv libraries and are not very consistent with each other. Here is a repost of my earlier code that now works on more systems. It converts as much as possible and replaces the rest with question marks: <?php if (!function_exists('utf8_to_ascii')) { setlocale(LC_CTYPE, 'en_AU.utf8'); if (@iconv("UTF-8", "ASCII//IGNORE//TRANSLIT", 'é') === false) { // PHP is probably using the glibc library (*NIX) function utf8_to_ascii($text) { return iconv("UTF-8", "ASCII//TRANSLIT", $text); } } else { // PHP is probably using the libiconv library (Windows) function utf8_to_ascii($text) { if (is_string($text)) { // Includes combinations of characters that present as a single glyph $text = preg_replace_callback('/\X/u', __FUNCTION__, $text); } elseif (is_array($text) && count($text) == 1 && is_string($text[0])) { // IGNORE characters that can't be TRANSLITerated to ASCII $text = iconv("UTF-8", "ASCII//IGNORE//TRANSLIT", $text[0]); // The documentation says that iconv() returns false on failure but it returns '' if ($text === '' || !is_string($text)) { $text = '?'; } elseif (preg_match('/\w/', $text)) { // If the text contains any letters... $text = preg_replace('/\W+/', '', $text); // ...then remove all non-letters } } else { // $text was not a string $text = ''; } return $text; } } } ---- Server IP: 72.52.91.14 Probable Submitter: 211.30.51.139 ---- Manual Page -- http://php.net/manual/en/function.iconv.php Edit -- https://master.php.net/note/edit/119137 Del: integrated -- https://master.php.net/note/delete/119137/integrated Del: useless -- https://master.php.net/note/delete/119137/useless Del: bad code -- https://master.php.net/note/delete/119137/bad+code Del: spam -- https://master.php.net/note/delete/119137/spam Del: non-english -- https://master.php.net/note/delete/119137/non-english Del: in docs -- https://master.php.net/note/delete/119137/in+docs Del: other reasons-- https://master.php.net/note/delete/119137 Reject -- https://master.php.net/note/reject/119137 Search -- https://master.php.net/manage/user-notes.php
