JavaScript to PHP Data Port

Yea this is probably easier that I would assume it to be. But here is the deal anyway. I have a javascript code that returns (actively as you type) how many words are in a certain text box. When the user is done with the box and submits the form, I need to take the word count that javascript gave on the page (which is contained in a span value at the moment), and somehow route it into a hidden input field or somehow save it to a PHP value, but I can't figure out how.

<span id="review_credits">0<span>

The ID review_credits is controlled and updated by this:

PHP Code:


function CountWords(text, target, bonus_target, wc_target, base) {
    var char_count = text.value.length;
    var fullStr = text.value + " ";
    var initial_whitespace_rExp = /^[^A-Za-z0-9]+/gi;
    var left_trimmedStr = fullStr.replace(initial_whitespace_rExp, "");
    var non_alphanumerics_rExp = rExp = /[^A-Za-z0-9]+/gi;
    var cleanedStr = left_trimmedStr.replace(non_alphanumerics_rExp, " ");
    var splitString = cleanedStr.split(" ");
    var word_count = splitString.length -1;
    if (fullStr.length <2) {
        word_count = 0;
    }
    words = word_count;
    bonus = Math.floor(words / 4);
    if (bonus > 50) { bonus = 50; }
    credits = Number(base) + Number(bonus);
    document.getElementById(target).innerHTML = credits;
    document.getElementById(bonus_target).innerHTML = bonus;
    document.getElementById(wc_target).innerHTML = words;
}

This script basically counts the words and then sends it back to the HTML page as you type in the textarea. (onKeyUp function). How can I convert that span ID (when the user is done) into a PHP variable that I can then store into a MySQL dbase?

Nevermind once again. I just used cookies from javascript to PHP, worked quite well. I know this can be dangerous, but once I set the cookie to a variable in PHP, I removed it right after, in a split second. It would be quite hard to hack that information or retreive it from that. But all the same if they did get the info, they wouldn't know what to do with it because the numbers are hard to decipher. Oh well for them! Haha.
