将PHP多维数组打印为HTML列表

<?php
function printArrayAsList($array) {
    echo "<ul>";
    foreach ($array as $key => $value) {
        echo "<li>";
        echo $key;
        if (is_array($value)) {
            printArrayAsList($value);
        } else {
            echo ": " . $value;
        }
        echo "</li>";
    }
    echo "</ul>";
}

// 示例多维数组
$array = array(
    "fruit" => array(
        "apple" => array(
            "color" => "red",
            "taste" => "sweet"
        ),
        "banana" => array(
            "color" => "yellow",
            "taste" => "sweet"
        )
    ),
    "vegetable" => array(
        "carrot" => array(
            "color" => "orange",
            "taste" => "crunchy"
        ),
        "broccoli" => array(
            "color" => "green",
            "taste" => "bitter"
        )
    )

printArrayAsList($array);
