在php中打印多维关联数组中的值

<?php
// 定义一个多维关联数组
$multiDimensionalArray = array(
    "key1" => array(
        "subkey1" => "value1",
        "subkey2" => "value2"
    ),
    "key2" => array(
        "subkey3" => "value3",
        "subkey4" => "value4"
    )
);

// 打印多维关联数组中的值
echo $multiDimensionalArray["key1"]["subkey1"]; // 输出：value1
echo $multiDimensionalArray["key2"]["subkey4"]; // 输出：value4
?>

<?php
// 遍历并打印多维关联数组中的所有值
foreach ($multiDimensionalArray as $key1 => $subArray) {
    foreach ($subArray as $key2 => $value) {
        echo "Key1: " . $key1 . ", Key2: " . $key2 . ", Value: " . $value . "<br>";
    }
}
?>
