问题描述
查看图层模式，只显示您所给予的内容是否正常，但您如何知道可用的内容？在TWIG中是否有列出所有定义的变量功能？有一种方法来转储变量？
View layer pattern where you only present what you have been given is fine and all, but how do you know what is available? Is there a "list all defined variables" functionality in TWIG? Is there a way to dump a variable?
我通过搜索找到的解决方案是定义一个函数，我可以使用我的现有的php调试工具通过，但是我发现的所有引用包括这两行很好的代码，但是它没有指定放置它们的位置。根据他们需要一个 $ loader 变量定义的事实，我尝试过/app/config/autoload.php，但$ loader是错误的。
The solution I found by searching for it was to define a function where I can use my existing php debug tools by injecting a function, but all references I have found to that includes these nice two lines of code, but nowhere is it specified where to place them. Going by the fact that they need a $loader variable defined, I tried /app/config/autoload.php but the $loader there was the wrong kind. Where do I place the php code for adding a twig function?
推荐答案
从Twig 1.5开始，正确的答案是使用转储功能。 。
As of Twig 1.5, the correct answer is to use the dump function. It is fully documented in the Twig documentation. Here is the documentation to enable this inside Symfony2.
{{ dump(user) }}
