PHPStorm代码提示对象数组的数组 [英] PHPStorm Code Hinting for array of object arrays

问题描述

在PHPStorm中，对象数组的代码提示既简单又很棒；

In PHPStorm, the Code Hinting for an object array is simple and awesome;

class FooList {
    public function __construct(){
        $this->_fooList[] = new Foo(1);
        $this->_fooList[] = new Foo(2);
        $this->_fooList[] = new Foo(3);
        $this->_fooList[] = new Foo(4);
    }

    /**
     * @return Foo[]
     */
    getFoos() {
        return $this->_fooList;
    }
}

如果我愿意...

$fooList = new FooList();

foreach($fooList as $foo)
{
    // Nice hinting.
    $foo->FooMethod...
}

PHPStorm知道$ fooList是一个Foos数组，因此知道$ foo的类型是Foo.

PHPStorm understands that $fooList is an array of Foos, and therefore knows that $foo's type is Foo.

问题是我想要一个FooList数组.

The problem is that I want an array of FooList.

$listOfLists[] = new FooList();
$listOfLists[] = new FooList();
$listOfLists[] = new FooList();
$listOfLists[] = new FooList();

foreach ($listOfLists as $fooList)
{
    foreach($fooList as $foo)
    {
        // No code hinting for $foo :(
    }
}

我知道您可以在foreach内部手动编写提示代码，例如...

I know that you can code hint manually inside the foreach, like...

foreach ($listOfLists as $fooList)
{
    foreach($fooList as $foo)
    {
        /** $var $foo Foo */
        // Code hinting, yay!!
    }
}

或者...

foreach ($listOfLists as $fooList)
{
    /** $var $fooList Foo[] */
    foreach($fooList as $foo)
    {
        // Code hinting, yay!!
    }
}

但是我认为这很困难，因为$ listOfLists是Foo数组的构建，所以每次实现listOfLists时，它都应该知道我在说什么，而无需提醒它.

But I think that is ugly, as $listOfLists is build of Foo arrays, it should know what I am talking about without reminding it every time I implement a listOfLists.

有没有办法实现这一目标?

Is there a way to implement this?

推荐答案

每个错误报告在评论中由@LazyOne链接 ，自 PhpStorm EAP 138.256 (因此在PHPStorm中8)现在支持统一的多级数组文档解析.

Per the bug report linked in the comments by @LazyOne, as of PhpStorm EAP 138.256 (thus in PHPStorm 8) uniform multi-level array doc parsing is now supported.

这意味着您现在可以执行以下操作:

This means you can now do this:

/**
 * @var $listOfLists Foo[][]
 */
$listOfLists[] = (new FooList())->getFoos();
$listOfLists[] = (new FooList())->getFoos();
$listOfLists[] = (new FooList())->getFoos();
$listOfLists[] = (new FooList())->getFoos();

foreach ($listOfLists as $fooList)
{
    foreach($fooList as $foo)
    {
        // Code hinting, yay!!
        $foo->fooMethod();
    }
}

并获得预期的结果:
