解决此代码时遇到问题.这些是数组

Having a problem on solving this code. These are the arrays

Array
(
    [0] => stdClass Object
        (
            [id] => 1
            [name] => delux
            [price] => 213
            [description] => 
            [tv] => 0
            [breakfast] => 0
            [park] => 0
            [wifi] => 0
            [ac] => 0
            [occupancy] => 
            [size] => 
            [view] => 
            [service] => 
            [terrace] => 0
            [pickup] => 0
            [internet] => 0
            [gym] => 0
            [note] => 
            [room_details] => {"img":["images/logo2.png","images/logo.png"]}
        )

    [1] => stdClass Object
        (
            [id] => 2
            [name] => hjghj
            [price] => 234
            [description] => 
            [tv] => 0
            [breakfast] => 0
            [park] => 0
            [wifi] => 0
            [ac] => 0
            [occupancy] => 
            [size] => 
            [view] => 
            [service] => 
            [terrace] => 0
            [pickup] => 0
            [internet] => 0
            [gym] => 0
            [note] => 
            [room_details] => 
        )

)

我想回显room_details下的每个图像，以使其显示为

I want to echo the per images under room_details to show like this

images/logo2.png
images/logo.png

images/logo2.png
images/logo.png

这是我的代码

    foreach ($roomandsuits as $i => $item) { 

      $array_links = json_decode($item->room_details, true); { 

        foreach  ($array_links as $key => $value) {   

          foreach ($value as $content) { 

       echo $content; 

       }           
       }     
      } 
     }

第三行出现错误，并显示如下

Error in 3rd line and shows like this

images/logo2.png
images/logo.png

警告:在第10行的C:\ xampp \ htdocs \ resort \ modules \ mod_roomandsuits \ tmpl \ default.php中为foreach()提供了无效的参数 images/logo.png

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\resort\modules\mod_roomandsuits\tmpl\default.php on line 10 images/logo.png

推荐答案

尝试以下代码.我在评论中添加了详细信息.

Try the below code. I added the details with comments.

foreach ($roomandsuits as $i => $item) { 

        if($item->room_details){  //check if value of $item->'room_details' not null

            $room_details = json_decode($item->room_details, true); //decode the json data

            if(!empty($room_details)){  //Check if room_details is not empty array
                $room = $room_details['img'];
                array_walk($room, function($value){  //using array_walk gate the value of room_details
                    echo $value .'<br/>';
                });

            }
        }

    }
