Note ": The value of the picture is

It really turned around. But what if it's an object? How to turn

You're not an array of PHP, it's JSON.

$s =<<< TXT "image": [                {                    "Local_path": "/upload/14d4aaf3c5ef5b93e6c4c7418428ea71.jpg",                    " picture_id ": 1                },                {                    " Local_path ":"/upload/14d4aaf3c5ef5b93e6c4c7418428ea71.jpg ",                    " picture_id ": 2                },                {                    "Local_path": "/upload/14d4aaf3c5ef5b93e6c4c7418428ea71.jpg",                    "picture_id": 3                }            ] TXT; $a = Json_decode (' {'. $s. '} ', 1); foreach ($a [' image '] as & $item) {  $item = array (    $item [' picture_id '] = > $item [' Local_path '],    ' picture_id ' = $item [' picture_id ']    );} Print_r ($a);

Array ([    image] = = Array (            [0] = = Array                (                    [1] = =/upload/ 14d4aaf3c5ef5b93e6c4c7418428ea71.jpg                    [picture_id] = 1                )            [1] = = Array                (                    [2] =/upload/ 14d4aaf3c5ef5b93e6c4c7418428ea71.jpg                    [picture_id] = 2                )            [2] = = Array                (                    [3] = =/ Upload/14d4aaf3c5ef5b93e6c4c7418428ea71.jpg                    [picture_id] = 3                )))        

Revert back to JSON

Echo Json_encode ($a, Json_pretty_print | Json_unescaped_slashes);

{"    image": [        {            "1": "/upload/14d4aaf3c5ef5b93e6c4c7418428ea71.jpg",            "picture_id": 1        },        {            "2": "/upload/14d4aaf3c5ef5b93e6c4c7418428ea71.jpg", "            picture_id": 2        },        {            "3": "/upload/ 14d4aaf3c5ef5b93e6c4c7418428ea71.jpg ",            " picture_id ": 3        }    ]}

 
  ' AAAAA ', ' picture_id ' =>1), array (' local_path ' = ' bbbbbbb ', ' picture_id ' =>2), array (' local_path ' = ') CCCCCCC ', ' picture_id ' =>3), function change ($arrr, $a =0) {foreach ($arrr as $key = $value) {$arr [$a] [$value [' picture_id ']]= $value [' Local_path ']; $arr [$a] [' picture_id ']= $value [' picture_id ']; $a + +;} return $arr;} $arry =change ($arr);p rint_r ($arry);? >

What if $arr is an object, not an array?

When the string is processed. Zu Ning give you the method you can not accept, then use the regular as a string processing it
