您不希望它们重复。您正在寻找的方法：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
                                        )

                                )

                        )

                )

        )

)

尝试使用array_merge_recursive：

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