annotating a local variable in php
提问by tzortzik
I am using Eclipse PDT and I want to annotate a local variable using Phpdoc.
我正在使用 Eclipse PDT，我想使用 Phpdoc 注释局部变量。
All I see is that I can annotate the variables/properties of a class using @varor even
@property, but how is this possible for a local variable?
我所看到的只是我可以使用@var甚至
注释类的变量/属性@property，但是这对于局部变量怎么可能呢？
How can I do something like this?
我怎么能做这样的事情？
function foo(){
/** @var Stock $a */
$a->save();
}

The Phpdoc standard does not cover these annotations (it only cover class properties with the @vartag); however, it is perfectly possible in Eclipse (e.g. PDT):
Phpdoc 标准没有涵盖这些注解（它只涵盖带有@var标签的类属性）；然而，这在 Eclipse 中是完全可能的（例如 PDT）：
/* @var $variable Type */
^ ^ `--- type
| variable
|
`--- single star
This also works in all other PHP IDEs like Netbeans or Phpstorm which is useful if you exchange your code with others.
这也适用于所有其他 PHP IDE，如 Netbeans 或 Phpstorm，如果您与其他人交换代码，这将非常有用。

示例代码：
<?php
/* @var $doc DOMDocument */
$doc->

This is an old question, but only for reference.
You must include the Usestatement for the Typein current file in order to @varannotation work
这是一个老问题，但仅供参考。您必须包含当前文件中的Use语句Type才能进行@var注释工作
<?php
use YourVendor\YourBundle\Entity\ProductType;
...
/* @var $product_type ProductType */
$foo = $product_type->getName();
