有时候我们需要在 Laravel 的 Blade 模版中定义一些变量,而 Blade 却没有提供这样的方法,所以我们这里为大家分享两种可以实现在 Blade 模版中定义变量的方法。
方法一
由于 Blade 模版中允许使用原生 PHP 代码,所以我们可以使用 PHP 语句来定义变量:
<?php $var = 'test'; ?>{{ $var }}
方法二
除了上面的方法,我们还可以使用 Blade 的注释语法来定义/设置变量。由于在 Blade 中 {{-- 这里是注释 --}}会被解析为 ,所以我们可以使用下面这样的语句来定义变量:
{{-- */$i=0;/* --}}// 这条语句会被 Blade 解析为<?php /* */$i=0;/* */ ?>
当然,我们还可以通过扩展 Blade 模版引擎的方法来实现,具体扩展方法可以参考 官方文档。
