I searched the line with the error. That's the line began to give an error on 7.0.11:
      $pass=$vfp->Eval("rtri(pass)");

This method should return a value.

In 7.0.11 has stopped working COM, which worked well in 7.0.10. The 500 error.

Log: Fixed bug #72922 COM called from PHP does not return out parameters

Hello, thanks for responding so quickly.

COM registration:
regsvr32 comTest.dll

comTest.dll is created in Embarcadero® Delphi 10 Seattle Version 23.0.21418.4207
(I have used COM objects created even in older versions of Delphi for almost a decade and it worked
fine).
comTest.dll was created just for testing purposes. I tested this exact version today with php 5.6 on
the same server and it worked OK.
Then with proper VC14 Win32 version of Apache and VC14 x86 PHP 7.0.10 and it returns correct result,
but in/out parameters keep input values instead of values provided inside COM.
I will send you an e-mail with the Delphi project (contains dlls - both Wind32 and Win64 versions)
and description of both php and apache setups(I do not know how to enclose it here).
The php test script and outputs for both versions will be enclosed. Both setups use 32-bit versions
but results for 64-bit versions are the same.
  

Method in COM object:

function TcomTestIF.test(const Param1: WideString; var Param2, Param3: WideString): WideString;
var res : string;
begin
  res := 'Param1=' + Param1 + '; Param2=' + Param2 + '; Param3=' +
Param3;
  Param2 := 'Output text Param2';
  Param3 := 'Output text Param3';
  Result :=  res;
end;

Thanks for the report. Please post the test class, or better a test project, along with the way you
register the class and other setup. Also need the current/expected output to compare.

Thanks.
