    Well, replace "" for "<?php", "</script>" for "?>", delete the "var" word and add a "$" sign on each variable and you will get your php code ;)

    i did this before and some of the functions are not running like for(i in var).

    I missed a few more changes you have to do:

    $combination = array();
    ...
    ...

    function getNextCombination
    global $combination; <------------ add this as function first line
    ...
    ...


    function showNext
    global $combination, $n, $r; <-------- add this line
    ...
    ...


    Replace this:
    for(i in combination)
    txt+=combination[i]+", ";
    window.status = txt;

    With this:
    foreach ($combination as $c)
    $txt.=$c.", ";
    echo $txt."<br>";

    Delete all html code, and the last line shoud be:
    init();


    I thinks now you can get it!
