PHP's Preg_match will verify that the # in the character is a comment
PHP's Preg_match will verify that the # in the character is considered a comment. The characters that are to be validated contain #, and the contents after the # are treated as comments, causing the validation to fail. This is a bug in PHP.

This is actually a misunderstanding. Preg_match no problem. When the AJAX request, the parameter with #, will be the following parameters are completely filtered out, need to add url_encode () to the parameter is OK.
