Hello I have these columns 'name', 'email', 'username' and 'ip' how would I check or highlight table row in blade if records has same ip?

This is my controller

 $promo = Promo::with(['participants' => function ($q) {
            $q->orderBy('winner', 'desc')->orderBy('created_at', 'desc');
        }])->find($id);

And this is my blade

@if($promos->participants->count() > 0)
    @foreach($promos->participants as $participant)
    <table>
      <tr >
        <td>Name</td>
        <td>Email</td>
        <td>Username</td>
        <td>IP</td>
      </tr>
      <tr>
        <td>{{$participant->name}}</td>
        <td>{{$participant->email}}</td>
        <td>{{$participant->username}}</td>
        <td>{{$participant->ip}}</td>
      </tr>
    </table>
    @endforeach
@endforeach

Another way is to get duplicates by taking advantage of Larvel's collection and have them passed in view.

$ips = $promos->participants->pluck('ip');
$duplicateIps = $ips->duplicates()->unique()->all();

So in your blade you would just need to check

@if($promos->participants->isNotEmpty())
@foreach($promos->participants as $participant)
<table>
  <tr >
    <td>Name</td>
    <td>Email</td>
    <td>Username</td>
    <td>IP</td>
  </tr>
  <tr @class(['duplicate-row' => in_array($participant->ip, $duplicateIps)]>
    <td>{{$participant->name}}</td>
    <td>{{$participant->email}}</td>
    <td>{{$participant->username}}</td>
    <td>{{$participant->ip}}</td>
  </tr>
</table>
@endforeach

Do like this

$ipList will store IPs when foreach runs and keeps checking whether they exist. If yes, add class duplicate-row to the <tr>

$ipList = [];
@foreach($promos->participants as $participant)
  <tr >
    <td>{{$participant->name}}</td>
    <td>{{$participant->email}}</td>
    <td>{{$participant->username}}</td>
    <td>{{$participant->ip}}</td>
  </tr>
  @if(!in_array($participant->ip, $ipList))
    <?php array_push($ipList, $participant->ip); ?>
  @endif
@endforeach

In CSS you can add

.duplicate-row {
  background-color: red;
}
