Here is one more small update now I got htis issue:

C:\php>php bdn.php
PHP Fatal error: Uncaught com_exception: Source: OpcLabs.BaseLib
Description: Attempt to add existing item into a set. in C:\php\bdn.php:12
Stack trace:

st...')

Fatal error: Uncaught com_exception: Source: OpcLabs.BaseLib

FYI bdn.php is the renamed example that you provide under console example of php named Browsedatanodes.php

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)
