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 . " " ;
}

?>

这输出Paul Jones 31

我怎样才能让它只输出名字fNames？

IEPaul, Mike, John

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

// output: Paul Mike John

您可能想要遍历主数组而不是其中的单个元素。

foreach($test as $item) {
    echo $item['fName'];
}
