How to use a Foreach loop in PHP/Blade for Laravel?

Question

Here is a quick question: Is there any way to optimise this code with a foreach loop or something like this?

@if(isset($tags[0]))
    <span class="label label-primary">{{ $tags[0] }}</span>
@endif
@if(isset($tags[1]))
    <span class="label label-primary">{{ $tags[1] }}</span>
@endif
@if(isset($tags[2]))
    <span class="label label-primary">{{ $tags[2] }}</span>
@endif
@if(isset($tags[3]))
    <span class="label label-primary">{{ $tags[3] }}</span>
@endif
@if(isset($tags[4]))
    <span class="label label-primary">{{ $tags[4] }}</span>
@endif
@if(isset($tags[5]))
    <span class="label label-primary">{{ $tags[5] }}</span>
@endif
@if(isset($tags[6]))
    <span class="label label-primary">{{ $tags[6] }}</span>
@endif
@if(isset($tags[7]))
    <span class="label label-primary">{{ $tags[7] }}</span>
@endif
@if(isset($tags[8]))
    <span class="label label-primary">{{ $tags[8] }}</span>
@endif
@if(isset($tags[9]))
    <span class="label label-primary">{{ $tags[9] }}</span>
@endif

Thank you and have a nice day/night !

You can do it simply like this :

@foreach ($tags as $tag)
    <span class="label label-primary">{{ $tag }}</span>
@endforeach

Shouldn't {{ $tags }} be {{ $tag }}? (Without the s)

You can use an @foreach loop (as suggested by other answers) or an @for loop. Use blade syntax for control structures (preceeded by an @ symbol)

@for($i = 0; $i <= 9; $i++)
@if(isset($tags[$i]))
<span class="label label-primary">{{ $tags[$i] }}</span>
@endif
@endfor

Thank you! I think I finally understood how for loop works !

Tim Lewis Over a year ago

No problem. And just so you're aware, a "thank you" comment is always nice, but should be avoided in favour of an action that actually closes the question. All of the answers posted here are valid; so consider upvoting them and marking one as an answer.

Haha, no, you upvoted my comment :P And I said upvote "them", not just mine.

Why, given an indexed array, would you need to range over 9 indices? @foreach will range over each of the elements in the $tags array.

@TimLewis That wording is much better, thank you. :)

Per the documentation, you can do @for loops.

@for ($i = 0; $i < 10; $i++)
    @if(isset($tags[$i]))
         <span class="label label-primary">{{ $tags[$i] }}</span>
    @endif
@endfor
