              string(7) "2306688"
            }
        }
    }

但我需要的是，无论差异在哪里，我也需要始终将路径放在数组中。我试图将

$value[“path”]

添加到数组

$difference

，但实际上不知道如何操作

我需要的结果是：

 array(1) {
      [0]=>
      array(1) {
        ["12345"]=>
        array(2) {
          ["fileName"]=>
          string(46) "monkey.jpg"
          ["path"]=>
          string(46) "Volumes/animals/monkey.jpg"
        }
      }
    }

试试这个

function array_diff_assoc_recursive($array1, $array2){
                    foreach($array1 as $key => $value){
                        if(is_array($value)){

测试结果：

array（2）{[0]=>array（2）{[“12345”]=>array（1）{[“fileName”]=>string（10）“monkey.jpg”}[“path”]=>NULL}[“path”]=>NULL}

你能回显$value[“path”]；代替$difference['path']=$value['path']；测试结果：

array（2）{[0]=>array（2）{[“12345”]=>array（1）{[“fileName”]=>string（10）“monkey.jpg”}[“path”]=>NULL}[“path”]=>NULL}

能否回显$value[“path”]；代替$difference['path']=$value['path']；并检查值是否正在打印是的，它只打印一次。如您所见，Akshay Khairmode仅使用$array1值作为结果输出，因此我们只需要它的“路径”字段。现在，我们需要将这个字段值放在$difference中，与$array2中的字段不同。这个特殊的位置在顶级“else-if”部分的内部。这部分是这个递归的“底部”。我将这些解释作为对用户问题的回答，但此问题已被删除。所以我就把它放在这里。可能有人需要它做些什么。正如您所看到的，Akshay Khairmode只使用$array1值作为结果输出，所以我们只需要它的“路径”字段。现在，我们需要将这个字段值放在$difference中，与$array2中的字段不同。这个特殊的位置在顶级“else-if”部分的内部。这部分是这个递归的“底部”。我将这些解释作为对用户问题的回答，但此问题已被删除。所以我就把它放在这里。也许有人需要它做点什么。
