问题

/**

  • @psalm-return \stdClass{foo?: string}
    */
    function returnObject(): \stdClass {
    $item2 = new \stdClass();
    $item2->foo = "asd";

What is the correct returning object definition in psalm?

  1. /** 
  2.  * @psalm-return \stdClass{foo?: string}
  3.  */
  4. function returnObject(): \stdClass {
  5.  $item2 = new \stdClass();
  6.  $item2->foo = "asd";
  7.     return $item2;
  8. }
  10. returnObject();
  12. ERROR: InvalidDocblock - 19:1 - Unexpected brace character in docblock for returnObject

您可以使用object来完成这个操作，但您不能对任何命名类进行此操作，包括stdClass：

  1. <?php
  2. /**
  3.  * @psalm-return object{foo?: string}
  4.  */
  5. function returnObject(): object {
  6.     $item2 = new stdClass();
  7.     $item2->foo = "asd";
  8.     return $item2;
  9. }
  11. $_v = returnObject();
  12. /** @psalm-trace $_v */;
  1. Psalm 输出 (使用提交 73ebe22)：
  3. INFO: Trace - 12:24 - $_v: object{foo?:string}
英文:

You can do this with object, but you can't do this with any named class, including stdClass:

  1. &lt;?php
  2. /** 
  3.  * @psalm-return object{foo?: string}
  4.  */
  5. function returnObject(): object {
  6.     $item2 = new stdClass();
  7.     $item2-&gt;foo = &quot;asd&quot;;
  8.     return $item2;
  9. }
  11. $_v = returnObject();
  12. /** @psalm-trace $_v */;
  1. Psalm output (using commit 73ebe22): 
  3. INFO: Trace - 12:24 - $_v: object{foo?:string}

The syntax you are using is not supported:

  1. /** 
  2.  * @psalm-return \stdClass{foo?: string}
  3.  */

You should only indicate the type, followed by an optional description:

  1. /** 
  2.  * @psalm-return \stdClass 返回一个具有设置了foo属性的对象。
  3.  */
