使用foreach循环访问多维数组的元素

Question

在下面的:

<?php
$test = array(
    array("fName" => "Paul", "lName" => "Jones", "Age" => "31"),
    array("fName" => "Mike", "lName" => "Hunt", "Age" => "3"),
    array("fName" => "John", "lName" => "Doe", "Age" => "32")
);
?>

<pre> <?php var_dump($test) ?> </pre>

<?php
foreach($test[0] as $key => $value) {
    echo $value . " " ;
}

foreach($test as $person) {
    echo $person['fName'] . " " ;
