$person = array('name' => "Fred", 'age' => 35, 'wife' => "Wilma");

echo "<table border=\"1\">";

array_walk($person, "printRow", "lightblue");

echo "</table>";

array_walk($baseArray, "walkFunction", $extraData);

function walkFunction($item, $index, $data)

{

echo "{$item} <- item, then border: {$data['border']}";

echo " color->{$data['color']}<br ...
