unable to link to _zval_dtor

[Paul A Norman]

I'm using latest Php4Delphi Delphi 2005 install with php 5.12

When I get that error message in the subject line I trace it to line 1111 in zenapi.pas which reads:
  if @_zval_dtor = nil then raise EPHP4DelphiException.Create('_zval_dtor');

This is my php.inc top portion does it look ok?

{.$DEFINE PHP4}
{.$DEFINE PHP433}
{.$DEFINE PHP430}

{If you are using PHP 4 please comment $DEFINE PHP5}

{PHP5 must be defined if you are using PHP5}
{$DEFINE PHP5}

{For PHP5 you have to define subversion}
{.$DEFINE PHP504}
{.$DEFINE PHP510}
{.$DEFINE PHP511}
{$DEFINE PHP512}

{.$IFDEF PHP433}
{.$DEFINE PHP4}
{.$UNDEF PHP5}
{.$UNDEF PHP504}
{.$UNDEF PHP510}
{.$UNDEF PHP511}
{.$UNDEF PHP512}
{.$ENDIF}

{.$IFDEF PHP430}
{.$DEFINE PHP4}
{.$UNDEF PHP5}
{.$UNDEF PHP504}
{.$UNDEF PHP510}
{.$UNDEF PHP511}
{.$UNDEF PHP512}
{.$ENDIF}

{$IFDEF PHP5}
  {$UNDEF PHP4}
  {$UNDEF PHP430}
  {$UNDEF PHP433}
{$ENDIF}

(To get error messages I have commented out QUIET_LOAD so that it takes place)

And this is what I am doing regarding loading the php5ts.dll (I have confirmed that it is loading ok)

I place an ini file in my project directory to point to the PHP I am using, so that I can have a development runtime that does not interfere with my loacal apache server php which is Php4xxx and is in my path. The I can have the php5ts.dll in catered for in my deployment with a sub directory php.

In zenapi.pas I have rewritten the function like this:

function LoadZEND(const DllFilename: string) : boolean;
var
  WriteFuncPtr  : pointer;
  whereIsPhp, hereIsPhP  : string;
  whereIsPhpIni : tinifile;
begin
  whereIsPhp := extractfilepath(paramstr(0))+'whereIsPhp.ini';
  if fileexists(whereIsPhp) then
     begin
      whereIsPhpIni := tinifile.Create(whereIsPhp);
{ lets me have a development path for Php and extensions, and a deployment path default
  whereIsPhp.ini should be in the application exe directory if I want to nominate a
  path other than application.exe sub dir /php/ as the location of the phpNNN.dll and php.ini
}
        try
        hereIsPhP := whereIsPhpIni.ReadString('Files','whereIsPhp',extractfilepath(paramstr(0)) +'php\');
         finally
            whereIsPhpIni.Free;
          end;
     end
     else
        hereIsPhP := extractfilepath(paramstr(0)) +'php\'; // [app.exe]\php\ is my default path

        hereIsPhp:= IncludeTrailingPathDelimiter(hereIsPhp)+DllFileName;
         showmessage(hereIsPhp);

  Result := false;
  PHPLib := LoadLibrary(PChar(hereIsPhp  ));
{$IFNDEF QUIET_LOAD}
  if PHPLib = 0 then raise Exception.CreateFmt('%s not found', [DllFileName]);
{$ELSE}
  if PHPLib = 0 then Exit;
{$ENDIF}

I've done everything again just plain with the php5 and php5/ext in my path, I've stopped zenapi.pas using my custom .ini, And I've tried using the DLLfolder and INIpath properties in TpsvCustomPHP although I can find no reference to them in the help file.

Still I get unable to link to _zval_dtor under Delphi 2005.

Any one got any ideas please?
