How to break a foreach loop in laravel blade view?
提问by Sagar Gautam
I have a loop like this:
我有一个这样的循环：
@foreach($data as $d)
@if(condition==true)
{{$d}}
// Here I want to break the loop in above condition true.
@endif
@endforeach
I want to break the loop after data display if condition is satisfied.
如果条件满足，我想在数据显示后打破循环。

From the Blade docs:
来自Blade 文档：
When using loops you may also end the loop or skip the current iteration:
使用循环时，您还可以结束循环或跳过当前迭代：
@foreach ($users as $user)
@if ($user->type == 1)
@continue
@endif
<li>{{ $user->name }}</li>
@if ($user->number == 5)
@break
@endif
@endforeach

Basic usage
基本用法
By default, blade doesn't have @breakand @continuewhich are useful to have. So that's included.
默认情况下，blade 没有@break，@continue哪些是有用的。所以这包括在内。
Furthermore, the $loopvariable is introduced inside loops, (almost) exactly like Twig.
此外，该$loop变量是在循环内部引入的，（几乎）与 Twig 完全一样。
Basic Example
基本示例
@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
