Hmmm... would be better as (:

<?php

function x( $x )
{
    echo 'bitten';
    echo 'shy';
    echo 'shy';
}

?>

Here's another one:

<?php

    class money
    {
        var $pennies = 0;

        function money( $amount=0 )
        {
            $this->pennies = $amount;
        }

        function save()
        {
            return true;
        }
    }

    class account
    {
        var $total = 0;

        function account( $init=0 )
        {
            $this->total = $init;
        }

        function add( $money )
        {
            $this->total += $money->pennies;
        }
    }

    $earned = new account();
    $penny  = new money( 1 );

    if( $penny->save() )
    {
        $earned->add( $penny );
    }

?>

Cheers,
Rob
