Answer 2

我们可以将array_walk_recursive（）用于多维数组。

array_walk() // Its useful for one-dimensional array.

array_walk_recursive() // Calling array_walk() function in recursively (i.e., function call inside the same function). 

Answer 3

<?php
    function myfunction($value,$key)
    {
        echo "The key $key has the value $value<br>";
    }
    $a1=array("a"=>"red","b"=>"green");
    $a2=array($a1,"1"=>"blue","2"=>"yellow");
    array_walk_recursive($a2,"myfunction");
?>

<强> ANSWER 键a的值为红色 键b的值为绿色 键1的值为蓝色 键2的值为黄色
