提问by Vincent
I want to add the following code to my laravel project to support the break and continue statements in blade.
我想将以下代码添加到我的 Laravel 项目中，以支持 Blade 中的 break 和 continue 语句。
This is the code:
这是代码：
Blade::extend(function($value)
{
return preg_replace('/(\s*)@(break|continue)(\s*)/', '<?php ; ?>', $value);
});
I have no idea however where to place it, any help would be appreciated?
我不知道把它放在哪里，任何帮助将不胜感激？

There's no requirement telling you where you should put the code, you could even put it in your routes.php(which is a bit messy of course). You only have to make sure that it's loaded when laravel processes a page view.
没有要求告诉你应该把代码放在哪里，你甚至可以把它放在你的routes.php（当然这有点乱）。你只需要确保它在 laravel 处理页面视图时被加载。
In this case, creating a new file blade_extensions.phpsomewhere and including it in start/global.phpmight be a good solution.
在这种情况下，在blade_extensions.php某处创建一个新文件并将其包含在其中start/global.php可能是一个很好的解决方案。
PS: Be sure to clear out your compiled views, as Blade only recompiles the views if it detects a change, so if you've just plonked in this code it won't work until you clear out the views.
PS：一定要清除你编译的视图，因为 Blade 只会在检测到变化时重新编译视图，所以如果你刚刚输入了这段代码，它在你清除视图之前不会工作。

Laravel 5 alternative
Laravel 5 替代品
1) create app/Providers/BladeServiceProvider.php
1）创建 app/Providers/BladeServiceProvider.php
<?php namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class BladeServiceProvider extends ServiceProvider
{
public function boot()
{
/* @datetime($var) */
\Blade::extend(function($view, $compiler)
{
$pattern = $compiler->createOpenMatcher('datetime');
return preg_replace($pattern, '<?php echo ->format(\'m/d/Y H:i\')); ?>', $view);
});
/* @eval($var++) */
\Blade::extend(function($view)
{
return preg_replace('/\@eval\((.+)\)/', '<?php ; ?>', $view);
});
}
public function register()
{
//
}
}
2) in config/app.phpadd
2）config/app.php添加
<?php
return [
// ...
'providers' => [
// ...
'App\Providers\BladeServiceProvider',
3) run php artisan clear-compiled
3）运行 php artisan clear-compiled
4) in your template use @datetime($updated_at)or @eval($var = 1), @eval($var++)for example
4) 在您的模板中使用@datetime($updated_at)或@eval($var = 1)，@eval($var++)例如
