} 模板引擎
Twig语法
{{...}} - 将变量或表达式的结果打印到模板。
{...} - 控制模板逻辑的标签。 它主要用于执行功能。
{...} - 评论语法。 它用于添加单行或多行注释。 控制器 /*** Route(/test/template_en)*/

通过.yml文件实现配置文件自定义Golang使用.yaml定义实际上两者是一个东西
一个Symfony项目有三种环境dev、test和prod
环境切换AppKernel类负责加载你指定的配置文件修改配置实现环境的切换
基础方法
切换目标文件
表单 传统意义上表单是通过构建一个表单对象并将其渲染到模版来完成的。现在在控制器里即可完成所有这些这个是啥意思简单点来说就是使用PHP创建表单而不是使用H5表单具体代码如下

修改配置文件
打开扩展php.ini extensionphp_fileinfo.dll 修改配置文件symfony\app\config\config.yml 类
?php

}
