Dynamic number of rows in Laravel Blade

This is correct:

    @foreach ($collection as $index => $element)
           {{$index}} - {{$element['name']}}
   @endforeach

And you must use index+1 because index starts from 0.

Using raw PHP in view is not the best solution. Example:

<tbody>
    <?php $i=1; @foreach ($aaa as $value)?>

    <tr>
        <td><?php echo $i;?></td>
        <td><?php {{$value->name}};?></td>
    </tr>
   <?php $i++;?>
<?php @endforeach ?>

in your case:

<thead>
    <th>number</th>
    <th>name</th>
</thead>
<tbody>
    @foreach ($aaa as $index => $value)
        <tr>
            <td>{{$index}}</td> // index +1 to begin from 1
            <td>{{$value}}</td>
        </tr>
    @endforeach
</tbody>

Try $loop->iteration variable.

`

<thead>
     <th>number</th>
     <th>name</th>
</thead>
<tbody>
    @foreach ($aaa as $value)
        <tr>
            <td>{{$loop->iteration}}</td>
            <td>{{$value}}</td>
        </tr>
    @endforeach
</tbody>
