Foreach loop@foreach @break @continue
Basic usage
By default, blade doesn't have @break and @continue which are useful to have. So that's included.
Furthermore, the $loop variable is introduced inside loops, (almost) exactly like Twig. So il shamelessly steal their description table:
| Variable | Description |
|---|---|
| loop.index1 | The current iteration of the loop. (1 indexed) |
| loop.index | The current iteration of the loop. (0 indexed) |
| loop.revindex1 | The number of iterations from the end of the loop (1 indexed) |
| loop.revindex | The number of iterations from the end of the loop (0 indexed) |
| loop.first | True if first iteration |
| loop.last | True if last iteration |
| loop.length | The number of items in the sequence |
| loop.parent | The parent context |
Usage example
@foreach($stuff as $key => $val)
$loop->index; // int, zero based
$loop->index1; // int, starts at 1
$loop->revindex; // int
$loop->revindex1; // int
$loop->first; // bool
$loop->last; // bool
$loop->even; // bool
$loop->odd; // bool
$loop->length; // int
@foreach($other as $name => $age)
$loop->parent->odd;
@foreach($friends as $foo => $bar)
$loop->parent->index;
$loop->parent->parentLoop->index;
@endforeach
@endforeach
@break
@continue
@endforeach
