    php is not available at the mo here in the college, so can someone run this through their php please and see what the output is, its a little exam question. I have a fair idea what it'll be, but just to be sure..many thanks..


    <?php

    $cash_on_hand=31;
    $meal=25;
    $tax=10;
    $tip=10;

    while(($cost=restaurant_check($meal, $tax, $tip))<$cash_on_hand) {
    $tip++;
    print "I can afford a tip of $tip% ($cost)\n";

    }

    function restaurant_check($meal, $tax, $tip) {
    $tax_amount=$meal*($tax/100);
    $tip_amount=$meal*($tip/100);
    return $meal+$tax_amount+$tip_amount;
    }

    ?>
