当键相同时在多维数组中查找数组差异

问题描述：

当键值相同时，我想找到两个多维数组之间的差异.我已经尝试了所有方法和许多Stackoverflow解决方案，但我无法做到这一点.

I want to find the difference between two Multi dimensional array when key value is same. I have tried every thing and so many Stackoverflow solution but I'm not able to do it.

数组1(DbData):-

$ajaxData = array("phase-5[]" =>
    array(
        '1' => "Admin Phase 1 Task 1",
        '2' => "Admin Phase 1 Task 2" 
    ),"phase-6[]" =>
    array(
        '1' => "Admin Phase 2 Task 1", 
        '2' => "Admin Phase 2 Task 2",
        '3' => "Admin Phase 2 Task 3" 
    ),"phase-7[]" =>
    array( 
        '1' => "Admin Phase 3 Task 1", 
        '2' => "Admin Phase 3 Task 2",
        '3' => "Admin Phase 3 Task 3"
    )
);

数组2(AjaxData):-

$dbData = array("phase-5[]" =>
    array(
        '0' => "Admin Phase 1 Task 1", 
        '1' => "Admin Phase 1 Task 2"
    ),"phase-6[]" =>
    array(
        '0' => "Admin Phase 2 Task 1",
        '1' => "Admin Phase 2 Task 2"
    ),"phase-7[]" =>
    array(
        '0' => "Admin Phase 3 Task 1",
        '1' => "Admin Phase 3 Task 2" 
    )
);

PHP代码:-

$ajaxDataList = array();
foreach ($ajaxData as $key => $value) {
    print_r($key);
    foreach ($value as $data) {
        $ajaxDataList[] = $data;
    }
}

$dbDataList = array();
foreach ($dbData as $key => $value) {
    print_r($key);
    foreach ($value as $data) {
        $dbDataList[] = $data;
    }
}
var_dump(array_diff($ajaxDataList, $dbDataList));

代码的O/P:-

 array (size=2)
  4 => string 'Admin Phase 2 Task 3' (length=20)
  7 => string 'Admin Phase 3 Task 3' (length=20)

我能够找到两个数组之间的差异，但无法找到与键的差异.我只需要在此处添加密钥.但是我做不到.

I'm able to find the difference between two array but I'm not able to find diffrence with key. I just need to add key here. But I'm not able to do it.

我需要这样的结构

array (size=2)
  'phase-6[]' => string 'Admin Phase 2 Task 3' (length=20)
  'phase-7[]' => string 'Admin Phase 3 Task 3' (length=20)

易于更改的解决方案

Easy solution with small changes

1.您需要在2个 foreach()代码

1.You need to add keys with some unique character (I used /) to all values of each array inside your 2 foreach() code

2.得到差异后，迭代该数组并使用唯一字符爆炸(我使用/)，然后将第一部分用作键，第二部分用作值，并将它们分配给最终结果数组

2.After getting difference iterate over this array and explode with a unique character (I used /) and then use first part as key and second part as value and assign them to your final result array

执行以下操作:-

$ajaxDataList = array();
foreach ($ajaxData as $key => $value) {
    foreach ($value as $data) {
        $ajaxDataList[] = $key.'/'.$data; //add key with each value
    }
}

$dbDataList = array();
foreach ($dbData as $key => $value) {
    foreach ($value as $data) {
        $dbDataList[] = $key.'/'.$data; // add key with each value
    }
}
$semi_final_array = array_diff($ajaxDataList, $dbDataList);

$final_array = [];

foreach($semi_final_array as $arr){ // iterate over difference array
   $exploded = explode('/',$arr); //explode data
   $final_array[$exploded[0]] = $exploded[1]; // use exploded array as key value pair
}

print_r($final_array);
