Operating system: Windows XP
PHP version: 5.2.5
PHP Bug Type: COM related
Bug description: com_get_active_object always fails
Description:
------------
com_get_active_object always returns "Operation Unavailable " even when it
should work for sure. Let me demonstrate:
Start up Microsoft Word (for example) on the server machine where Apache
and PHP are running. Then put the following text in a file called x.vbs:
Dim app
Set app = GetObject(,"Word.Application")
if app is nothing then
wscript.echo "Got nothing"
else
wscript.echo "Got it!"
end if
Execute it by typing: cscript x.vbs.
Note that it works fine. Yet the following line in a PHP script always
returns "Operation Unavailable ":
$obj = com_get_active_object("Word.Application");
Using: $obj = new COM("Word.Application") works (meaning PHP COM is
working).
I just upgraded Apache to 2.2.6 and PHP 5.2.5 (using the Windows
installation executable binaries with pretty much default settings, except
PHP is in c:\PHP525 and I checked the options for MS and MYSQL databases).
Bugzilla and several PHP applications all work fine.
But it seems com_get_active_object *always* fails. I have Googled and I
can not find any examples of it out there or any security or other settings
related to it.
If it just calls GetObject, then how come calling GetObject from VBScript
works but in PHP does not? I did discover that some GetObject calls are
disabled under IIS for security reasons, but I am using Apache and there is
no reference to any setting that needs to be turned on before this will
work.
Reproduce code:
---------------
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml"; lang="en-US">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"
/>
<title>Test</title>
</head>
<body>
<?php
echo("<p>Attempting to retrieve COM Object</p>");
$obj = com_get_active_object("Word.Application"); //Fails!
if ($obj) {
echo("<p>Object Found</p>");
} else {
echo("<p>Object NOT Found</p>");
}
?>
</body>
</html>
Expected result:
----------------
No error. You should see:
Attempting to retrieve COM Object
Object Found
Actual result:
--------------
You see:
Attempting to retrieve COM Object
If PHP error tracing is enabled you also see:
Fatal error: Uncaught exception 'com_exception' with message 'Operation
unavailable ' in C:\ApacheDocumentRoot\test_com.php:10 Stack trace: #0
C:\ApacheDocumentRoot\test_com.php(10):
