==========================================

I believe there are two wrong references to mb_regex_encoding() on the following two pages:

http://www.php.net/function.mb-internal-encoding#refsect1-function.mb-internal-encoding-notes

http://www.php.net/function.mb-strrpos#refsect1-function.mb-strrpos-notes

These pages aren't related to regular expressions - and the source code and a test indicates that their internal character encoding is given by the encoding of mb_internal_encoding(), instead of mb_regex_encoding().

Thank you very much for your help! :)

<?

mb_internal_encoding("UTF-16");
echo mb_strrpos("\x00\x74\x00\x65\x00\x73\x00\x74","\x00\x73"); // 2

mb_internal_encoding("UTF-8");
echo mb_strrpos("\x00\x74\x00\x65\x00\x73\x00\x74","\x00\x73"); // 4

mb_regex_encoding("UTF-16"); // does not seem to change anything
echo mb_strrpos("\x00\x74\x00\x65\x00\x73\x00\x74","\x00\x73"); // 4

mb_regex_encoding("UTF-8"); // does not seem to change anything
echo mb_strrpos("\x00\x74\x00\x65\x00\x73\x00\x74","\x00\x73"); // 4

?>
