Digg  mb_check_encoding
Check if the string is valid for the specified encoding
(PHP 4 >= 4.4.3, PHP 5 >= 5.1.3)
Code Examples / Notes » mb_check_encodingolexa riznyk
This function returns true incorrectly sometimes (at least when internal encoding is UTF-8 and encoding being checked for is Windows-1251, and PHP version 4.4.4 on FreeBSD 6.2 STABLE). This bug was not answered in bug reporting yet, so here is a workaround: Instead of checking for this: <?php mb_check_encoding($var, $destination_encoding) ?> check for this: <?php mb_check_encoding($var, $destination_encoding) && mb_substr_count($var, '?', $source_encoding) == mb_substr_count(mb_convert_encoding($var, $destination_encoding, $source_encoding), '?', $destination_encoding) ?> The idea is to count question mark characters ('?') in original value and converted value, because mb_convert_encoding function uses question marks to substitute characters that are not valid in destination encoding. |
