From the foreach manual page:

--------
/* foreach example 2: value (with key printed for illustration) */

$a = array (1, 2, 3, 17);

$i = 0; /* for illustrative purposes only */

foreach($a as $v) {
    print "\$a[$i] => $k.\n";
}
---------

that print statement should be 
    print "\$a[$i] => $v.\n";
