setting variables inside a Laravel foreach loop

Question

I've just started using the framework. In plain PHP after the opening foreach I would then set the variables then close the php tag but then from what I can work out you have to then do the Laravel @foreach tags and then open and close @php. Is there a way around this as it seems like a lot of extra work and code?

        @foreach($steps as $row)
            @php
                $title = $row->title;
                $text = $row->text;
                $i = 1;
            @endphp
            <div class="steps-item grid-wrap">
                <div class="number"
                @if($text || $title)
                    <div class="text-wrap">
                        @if($title)
                            <h2>{{$title}}</h2>
                        @endif
                        {!! $text !!}
                    </div>
                    @php
                        $i++;
                    @endphp
                @endif
            </div>{{--END steps-item--}}
        @endforeach

Couldn't/shouldn't this be done in the controller or model?

Since blade is no PHP, you have to return to PHP with that directive. But you can set/use the variables without doing that in your case:

@foreach($steps as $i => $row)
    <div class="steps-item grid-wrap">
        <div class="number"
        @if($text || $title)
            <div class="text-wrap">
                @if($title)
                    <h2>{{ $row->title }}</h2>
                @endif
                {!! $row->text !!}
            </div>
            @php
                $i++;
            @endphp
        @endif
    </div>{{--END steps-item--}}
@endforeach

If you still want to set variables, there's a Laravel package called alexdover/blade-set. But as @brombeer pointed out, in most cases it's highly recommended to set all necessary variables in the controller before passing them to the view.

Use laravel provided loop variables:

$loop->iteration    The current loop iteration (starts at 1).

It will increment in every loop iteration automatically.

e.g:
First iteration = $loop->iteration => 1 ;
Second iteration = $loop->iteration => 2 ;
so on until loop ends.

Check docs: The Loop Variables

You can use a @for directive with sizeof($steps) like that:

@for($i=0; $i<= sizeof($steps)-1; $i++)

@endfor

@foreach ($steps as $row)

<div class="steps-item grid-wrap">
    <div class="number">
        <div class="text-wrap">
            @if ($row->title != '')
                <h2>{{$row->title}}</h2>
               /* if you want to display another title when its blank you can 
                use if-else here otherwise not need to use if conditions for 
                title and text */
            @endif
            @if ($row->text != '')
               {!! $row->text !!}
            @endif
        </div>
    </div>
</div>

@endforeach

{{-- for an example you have $steps values like

$steps = Array( [0] -> 1, [1] -> 'title', [2] -> 'text' );

if you want this array key value pair you have to use @foreach like @foreach ($steps as $key=>$value) @endforeach

you can use key value in @foreach loop only --}}
