第一个数组

first array

    [0] => Array
        (
            [file] => newhotfolder.gif
            [path] => images/newhotfolder.gif

推荐答案

这些是多维关联数组，您可以递归地执行array_diff_assoc，在此处查找:array-diff-assoc-php [

These are multi-dimensional associative arrays, you can recursively do an array_diff_assoc, find out here: array-diff-assoc-php[^]
See example:

<?php
/*

combination of efforts from previous notes deleted.

function array_diff_assoc_recursive(

array1，

array2) { foreach(

array2) { foreach(
