Laravel get data out of foreach loop - php

Question

The below code shows the error (on the line if ($response) {):
Undefined variable: response
I am checking the if condition inside the foreach because I wanted to check whether each id in the UserEnabledNotifications table exists in notifications table. Also dump($response); inside the if condition of foreach shows data.
Can I get the data in $response outside the foreach loop? What shall I try?
$notificationData = UserEnabledNotifications::all();
foreach ($notificationData->where('status', 'true') as $user => $value) {
if (Notifications::where('userEnabledNotificationsId', $value['id'])->exists() == false) {
$notificationTypeName = NotificationTypes::where('id', $value['notificationTypesId'])
->value('notificationTypeName');
$userData = User::where('id', $value['userId'])
->get()
->toArray();
$data = [];
$data['notificationTypesId'] = $value['notificationTypesId'];
$data['notificationTypeName'] = $notificationTypeName;
$data['userId'] = $value['userId'];
$data['email'] = $userData[0]['email'];
$data['recipientName'] = $userData[0]['FullName'];
$data['userEnabledNotificationsId'] = $value['id'];
$response = Notifications::create($data);
//dump($response);
$tags[] = $response;
}
}
if ($response) {
return response()->json([
'message' => 'success',
'data' => $tags,
'statusCode' => 200,
'status' => 'success'
], 200);
}

Answer 1

You define $response in first if body but you need $response = null above that.

Answer 2

You might create a private or protected variable, and put it outside, and then access it directly or via functions
$notificationData = UserEnabledNotifications::all();
private $reponse = null;
foreach ($notificationData->where('status', 'true') as $user => $value) {
if(Notifications::where('userEnabledNotificationsId',$value['id'])->exists()==false){
$notificationTypeName = NotificationTypes::where('id', $value['notificationTypesId'])->value('notificationTypeName');
$userData = User::where('id', $value['userId'])->get()->toArray();
$data = [];
$data['notificationTypesId'] = $value['notificationTypesId'];
$data['notificationTypeName'] = $notificationTypeName;
$data['userId'] = $value['userId'];
$data['email'] = $userData[0]['email'];
$data['recipientName'] = $userData[0]['FullName'];
$data['userEnabledNotificationsId'] = $value['id'];
$response = Notifications::create($data);
$tags[] = $response;
}
}
if ($response) {
return response()->json([
'message' => 'success',
'data' => $tags,
'statusCode' => 200,
'status' => 'success'
], 200);
}
But now each place you would need to check whether responses are null or not.
Why private or protected or public?
Check this answer : What is the difference between public, private, and protected?
I quote
public scope to make that property/method available from anywhere, other classes, and instances of the object.
private scope when you want your property/method to be visible in its own class only.
protected scope when you want to make your property/method visible in all classes that extend current class including the parent class.

Answer 3

Simply declare a null or an empty array in a $response variable and you will be able to get the data out of the loop!
