JetBrains WebIDE: PHP variable type hinting?
提问by kolypto
Is there a way to hint WebIDE that a variable has some type? I have to iterate an array of objects, and there's no auto-completion available. This helps in ZendStudio:
有没有办法提示 WebIDE 变量具有某种类型？我必须迭代一个对象数组，并且没有可用的自动完成功能。这有助于 ZendStudio：
/* @var ClassName $object */
I know there's a feature in JetBrains to declare an array of objects:
我知道 JetBrains 中有一个功能可以声明一个对象数组：
/**
* @return ClassName[]
*/
But this works only with function's return type.
但这仅适用于函数的返回类型。

/* @var ClassName $object */is a non-valid PHPDOC comment and is not parsed in the current version of Web IDE. Use double asterisks to make it work:
/* @var ClassName $object */是无效的 PHPDOC 注释，不会在当前版本的 Web IDE 中解析。使用双星号使其工作：
/** @var ClassName $object */
Also, you can annotate $arrayin foreach($array as $var)with /** @var ClassName[] $array */and $vartype will be deduced automatically.
此外，您可以$array在foreach($array as $var)with 中进行注释/** @var ClassName[] $array */，$var类型将被自动推导。

As already pointed out, PhpStorm will use regular phpdoc blocks:
正如已经指出的，PhpStorm 将使用常规的 phpdoc 块：
/** @var ClassName $object */
However, since 2.1it also supports Netbeans/Eclipse/Zend @var annotations:
但是，从2.1 开始，它还支持 Netbeans/Eclipse/Zend @var 注释：
/* @var $object ClassName */
Please note the comment starts with /*rather than /**(thus it won't show up if you generate actual documentation with phpdoc). Also, the arguments are swapped, though PhpStorm accepts any order:
请注意注释以/*而不是开头/**（因此如果您使用 phpdoc 生成实际文档，它将不会显示）。此外，参数被交换，尽管 PhpStorm 接受任何顺序：
/* @var ClassName $object */
Last but not least, they can precede almost any arbitrary line of code (technically, phpdoc blocks are restricted to certain items).
最后但并非最不重要的一点是，它们几乎可以在任何任意代码行之前（从技术上讲，phpdoc 块仅限于某些项目）。
Edit:as of 2019, Netbeans/Eclipse/Zend @var annotations seem to be mostly abandoned. NetBeans 11 no longer supports them and in general they aren't supported by other IDEs. I suggest to use the other syntax.
编辑：截至 2019 年，Netbeans/Eclipse/Zend @var 注释似乎大多被放弃。NetBeans 11 不再支持它们，并且通常其他 IDE 不支持它们。我建议使用其他语法。
