PHP减去URL中的符号（rawurlencode vs urlencode）

Question

I've tried using rawurlencode and urlencode, both give me "&" and the other "+".

What i'm asking is, is there a PHP function that puts "-" in between words, like on Stack Overflow?

Thanks

If thats all you're trying to do, you could just use:

    $url = str_replace(" ", "-", $url);

And then use urlencode to encode it after that. E.G.:

    function myurlencode($url)
    {
        return urlencode(str_replace(" ", "-", $url));
    }

EDIT

And according to the PHP manual, it replaces all non-alphanumeric characters except -_. with a percent (%) sign followed by two hex digits and spaces encoded as plus (+) signs.
