PHP将多维数组中的值添加到一个数组中

<?php
// 创建一个多维数组
$multiArray = array(
    array("apple", "banana", "cherry"),
    array("orange", "grape", "mango"),
    array("pear", "watermelon", "pineapple")
);

// 创建一个空数组，用于存储多维数组中的值
$newArray = array();

// 使用foreach循环遍历多维数组
foreach ($multiArray as $subArray) {
    // 使用foreach循环遍历子数组中的值
    foreach ($subArray as $value) {
        // 将值添加到新数组中
        array_push($newArray, $value);
    }
}

// 打印新数组中的值
print_r($newArray);
?>
