That is clear from the info I provided, as each installer has a unique name. Hover over the link on the PHP site and you will see the name in the browser. "php-7.2.8-nts-Win32-VC15-x64", which I have used, is the installer for "VC15 x64 Non Thread Safe (2018-Jul-18 12:51:38)".

But they should all work with respect to QuickOPC (this is not to say that they all should work in IIS etc. - that's not our concern).

I attempted to reproduce the problem on Windows Server 2012 R2, but without success. I have used some older PHP version that we have tested with before (5.6.x), and then the latest one (7.2.8), from windows.php.net/download/ .

Nevertheless, I suspect the issue might be what we have already addressed in the upcoming QuickOPC 2018.3. We have therefore projected the fix back into 2018.2, and made a new build that is now available on the Download page of our Web site. Please download the latest build (it should identify itself as 5.53.293.1 or later on the 1st page of Setup) and re-test.

It is also possible that the error was an inappropriate indication of some other problem. If you still get problems, but a different error message, we would need the new error text.

Now I have problem brosing nodes ....


Server is 2012 R2 so it is fully compatible and we use the latest COM opc component downloaded today

so when I use this in PHP DON'T WORK:

<?php

$opcServer = "opc.tcp://XXX.XXX.XXX.XXX:49320";
$opcPath = 'ns=2;s=MOYNORHB1.RHB1';

$client = new \COM("OpcLabs.EasyOpc.UA.EasyUAClient");
$monitoringParameters = new \COM("OpcLabs.EasyOpc.UA.UAMonitoringParameters");

try {
$nodeElements = $client->BrowseDataNodes($opcServer, $opcPath);
} catch (\Exception $e) {
echo $e->getMessage();
}
foreach ($nodeElements as $nodeElement) {
echo $nodeElement->BrowseName.' '.$nodeElement->NodeId.PHP_EOL;
}


the similar code in delphi on the same machine:

var
Client: OpcLabs_EasyOpcUA_TLB._EasyUAClient;
Count: Cardinal;
Element: OleVariant;
NodeElement: _UANodeElement;
NodeElementEnumerator: IEnumVariant;
NodeElements: _UANodeElementCollection;
begin
// Instantiate the client object
Client := CoEasyUAClient.Create;

NodeElements := Client.BrowseDataNodes(
'opc.tcp://XXX.XXX.XXX.XXX:49320/',
'ns=2;s=MOYNORHB1.RHB1');

NodeElementEnumerator := NodeElements.GetEnumerator;
while (NodeElementEnumerator.Next(1, Element, Count) = S_OK) do
begin
NodeElement := IUnknown(Element) as _UANodeElement;
Memo1.Lines.Add(NodeElement.BrowseName.ToString+ ' : ' + NodeElement.NodeId.ToString);
end;
end;

WORKS PERFECLT

so what is the issue ?


ah I got this error in PHP:


Source: OpcLabs.BaseLib
Description: Attempt to add existing item into a set.
C:\inetpub\wwwroot\opc>


PS. Your BroseDataNodex example return excatly same error .... this is with version of PHP 7.0.7 with 7.2.2 don't give me any error and no node showed... (Nice)
