How to check object of a model is empty in laravel?

Question

I am accessing my database using model by using following code.

$persons = WysPerson::where('family_id', $id)->get();

I checked $personsis empty or not by using following code.

if($persons){
        var_dump($persons);
    }

Actually $persons is empty. But I am getting result for var_dump as

object(Illuminate\Database\Eloquent\Collection)#417 (1) { ["items":protected]=> array(0) { } }

How will I check $persons is empty? Can anyone help?

@Naruto collections are not arrays. isEmpty is the right method as answered below by Angel — Merhawi Fissehaye, Apr 14 '15 at 11:16

The title is misleading. "Object of a model is empty" implies whether an instance of `\Illuminate\Database\Eloquent\Model` has no attributes set (which is why I'm in here). You're really asking whether the collection returned by a `get` operation on a model is empty. — Jay Bienvenu, Jan 18 '23 at 22:16

You can use the isEmpty method:

I tried to use isEmpty like "var_dump(isEmpty($persons));" .. but I am getting error "Call to undefined function isEmpty()"? – manoos Apr 14 '15 at 11:20

Its a method of the collection, you should be calling $persons->isEmpty(); – Angel Iliikov Apr 14 '15 at 11:31

If you have eloquent collection, call the function isEmpty() like this:

$persons->isEmpty();

This return true or false. Hope this helps.

Use the count function

@if (count($persons))

there is an issue with your answer, if you forgot to execute the query with ->get() and just leave the query in place count will return 1. isEmpty will throw an exception which in the grand scheme of things is better. – Cptmaxon Dec 15 '15 at 09:30
And checking collection count wont work, till it's Laravel collection – Sigismund Jun 17 '16 at 10:40

You can use isEmpty() method.

At the same time you can check it by simply with count() method before once you fetch the data.

    $count = WysPerson::where('family_id', $id)->count();
    if($count==0){
       return redirect()->back()->withErrors('Empty Data');
     }
    $persons = WysPerson::where('family_id', $id)->get();
