Extracting data from multiple Nested Json using PHP-CodePudding

Here's the json

{"msg":"OK","server_time":"2021-11-19 16:41:22","status":200,"result":{"total_pages":1,"files":[{"download_url":"DOWNLOADLINKHERE1","single_img":"IMAGEURLHERE1","file_code":"CODEHERE1","title":"TITLEHERE1"},{"download_url":"DOWNLOADLINKHERE2","single_img":"IMAGEURLHERE2","file_code":"CODEHERE2","title":"TITLEHERE2"}],"results_total":"2","results":2}}

Here's my code

$json = json_decode($data);
foreach($json["result"] as $result){
    foreach($result["files"] as $file){
        echo $file["file_code"];
    }
}

I want to extract all values from the "file_code". I got an error Warning: Invalid argument supplied for foreach()

I was able get the VALUE of the first one using

echo $json->result->files[0]->file_code;

Is it possible to use a LOOP for the files[0]?

I replicated your situation and it turns out that your JSON is invalid. You're missing a } at the end.

The reason for not getting an exception is because json_decode does not throw an error by default. You can make it do so by adding the JSON_THROW_ON_ERROR flag, read the docs for more info.

This works perfect for me. If you have any thoughts please feel free to correct me.

$num = count($json->result->files);
echo $num;

for($i=0;$i<$num;$i  )
    {
echo $json->result->files[$i]->file_code;
    }
