[PHP] Error "staticMethod.notFound" for NOTION.COM api

[WolfgangHG]

Found as part of #7774:

Using the source code from 2026-06-17 and this command:

.\it\generate-code.ps1 -descriptionUrl https://developers.notion.com/openapi.json  -language "php" -dev
.\it\exec-cmd.ps1 -descriptionUrl https://developers.notion.com/openapi.json  -language "php"

The generated client does not compile:

Error:  [ERROR] Found 3 errors                                                         

This is the relevant code:

class InternalOrExternalFileWithNameResponse extends InternalOrExternalFileWithNameResponseCommon implements AdditionalDataHolder, Parsable 
{
    ...
   
    public function __construct() {
        parent::__construct();
        $this->setAdditionalData([]);
    }

The base class has no "_construct" function - is this the reason for the error?

class InternalOrExternalFileWithNameResponseCommon implements Parsable 
{

I’d like to investigate this issue and try to work on a fix.

From the report, it seems the generated PHP models call parent::__construct() even when the parent class does not define a constructor.

I’m currently reproducing the issue and looking into the PHP generator logic.

@Michal-Pinchasi Many thanks for the fix! I could verify that the compilation error is gone.
