Editing the scope of an API URL

Question

I am editing an API scope based on the site's URL so if I have example.com/?Wab_id=15 it will edit the API scope to

?scope=accepted&view=films&wab_id=15

I was thinking I could have something like

$ApiData = file_get_contents('http://example.com/api/?scope=accepted&view=films/&wab_id=$id');

and then using Get to retrieve the id that's being passed into the URL to edit the URL of the API. I also tried looping though the entire JSON and then calling the a key inside of the array but also didn't get much luck. My code is below:

$ApiData = file_get_contents('http://example.com/api/?scope=accepted&view=films');
$obj = json_decode($ApiData, true);
$data = $obj;
//here you load $data with whatever you want.
$id = $_GET['id'];
foreach ($data[$id] as $key=>$value){
echo "$key -> $value<br>";
}
?>

but this returns a error of:

Invalid argument supplied for foreach()

I've also tried looping through the Muti array with a foreach inside of a foreach and have displayed the values the code and results are below:

$obj = json_decode($ApiData, true);
$data = $obj;
//here you load $data with whatever you want.
 
foreach ( $data as $film ){
  foreach ( $film as $key=>$val ){
    echo "$key -> $val<br>";
  }
}

results

wab_id -> 95

As I mentioned in my comment:

Are you passing wab_id, Wab_id, or id to your server where you will access with $_GET? Because it's not clear under which key you are passing it to yourself and if you are using the correct one - which may be the issue you are having right now.

After you have that squared away manipulating the API params should be a simple affair:

$api = "http://example.com/api/";
$params = array(
   'scope' => 'accepted',
   'view' => 'films',
);

// you need to match the key you are using here to what you are passing
// to your URL
if (isset($_GET['id'])) {
  $params['wab_id'] = $_GET['id'];
}

$url = $api . '?' . http_build_query($params);

Now for the last part, you really should use cURL, Http... or really any thing other than file_get_contents because it doesn't really give you a very good way to handle errors you may come across. I'll give you a quick example using cURL:

$client = curl_init();
curl_setopt_array($client, array(
   CURLOPT_RETURNTRASNFER => true,
   CURLOPT_URL => $url // the one we dynamically built above
));

$responseText = curl_exec($client);

if ($responseText !== false) {
   $responseInfo = curl_getinfo($client);

   if ($responseInfo['http_code'] === 200) {
       // http status ok - you may need to take action based 
       // on other http status codes but I'm not going to delve into that here.
       
       $data = json_decode($responseText, true);
       print_r($data);
   
    } else {
      printf('Error accessing data: HTTP Status %s', $responseInfo['http_code'];
    }
} else {
  printf('Error: (%s) %s', curl_errno($client), curl_error($client));
}

curl_close($client);
