如何在 PHP 中合并下面的数组？

Question

我有两种 json 格式，我正在将 json 转换为数组然后合并它，但它不起作用。

看下面两种json格式。

下面是我的 PHP 代码，它没有合并数组，这里有什么问题？

$arr1 = json_decode('{
   "PatchDeployment":[
      {
         "ehubid":"123",
         "tomcats":[
           
            {
               "tomcatname":"mytomcat",
               "servername":"myserver",
               "serverip":"xx.xx.xx.xxx",
               "tomcat_statuses":{
                  "stoptomcat":"Success"
               }
            }
         ]
      }
   ]
}', true);


$arr2 = json_decode('{
   "PatchDeployment":[
      {
         "ehubid":"123",
         "tomcats":[
            {
               "tomcatname":"mytomcat",
               "servername":"myserver",
               "serverip":"xx.xx.xx.xxx",
               "tomcat_statuses":{
                  "checkdb":"Failed",
                  "checkhub":"couldnt connect to host"
               }
            }
            
         ]
      }
   ]
}', true);


$mergedarray = array_merge($arr1, $arr2);

我希望数组在合并 $mergedarray 后应该像下面这样：

Array
(
    [PatchDeployment] => Array
        (
            [0] => Array
                (
                    [ehubid] => 123
                    [tomcats] => Array
                        (
                            [0] => Array
                                (
                                    [tomcatname] => mytomcat
                                    [servername] => myserver
                                    [serverip] => xx.xx.xx.xxx
                                    [tomcat_statuses] => Array
                                        (
                                            [checkdb] => Failed
                                            [checkhub] => couldnt connect to host
                                            [stoptomcat]=> Success
                                        )

                                )

                        )

                )

        )

)

我正在将两个数组合并到 php

谁能帮我尽快解决这个问题？

Answer 1

尝试使用

array_merge_recursive

：

$mergedArr = array_merge_recursive($arr1, $arr2);

Answer 2

你不希望他们重复。您要找的方法：

array_replace_recursive

代码

$arr1 = json_decode('{
    "PatchDeployment":[
        {
            "ehubid":"123",
            "tomcats":[

                {
                "tomcatname":"mytomcat",
                "servername":"myserver",
                "serverip":"xx.xx.xx.xxx",
                "tomcat_statuses":{
                    "stoptomcat":"Success"
                }
                }
            ]
        }
    ]
}', true);

$arr2 = json_decode('{
    "PatchDeployment":[
        {
            "ehubid":"123",
            "tomcats":[
                {
                "tomcatname":"mytomcat",
                "servername":"myserver",
                "serverip":"xx.xx.xx.xxx",
                "tomcat_statuses":{
                    "checkdb":"Failed",
                    "checkhub":"couldnt connect to host"
                }
                }

            ]
        }
    ]
}', true);

$mergedarray = array_replace_recursive($arr1, $arr2);
print '<pre>';
print_r($mergedarray);
print '</pre>';
exit;

结果

Array
(
    [PatchDeployment] => Array
        (
            [0] => Array
                (
                    [ehubid] => 123
                    [tomcats] => Array
                        (
                            [0] => Array
                                (
                                    [tomcatname] => mytomcat
                                    [servername] => myserver
                                    [serverip] => xx.xx.xx.xxx
                                    [tomcat_statuses] => Array
                                        (
                                            [stoptomcat] => Success
                                            [checkdb] => Failed
                                            [checkhub] => couldnt connect to host
                                        )

                                )

                        )

                )

        )
