I seem to have a problem running the exec() function. I created a php program that when user uploads a file it will automatically open an anti-virus program and check the specific file, but the execution didn't occur at all. Nothing happened. So I was wondering if exec will ever work if you run any win32 executable programs using exec(). Pease fix the bug please please. 

If you can give me a solution on how to resolve such problem, please let me know.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

I've had this same thing happen to me.  Using php4.0.6 running an system command works fine and will return output.  As soon as I upgraded to 4.2.3 the script no longer works.  I'm running win2k with PHP4.2.3 and have apache running as a local user with permission to exec and read the file.  

I have found that if there is more than one set of double quotes in the command it will no longer work.  Also putting the command into a .bat file will allow it to be run correctly if I call the .bat file.

	$cmd ="\"c:\\dialup\\rcl.exe\" -c -u \"dialup_username\" -p \"dialup_password\"";
	$output = `$cmd`;

	echo "Attempted: $cmd<br>";
	echo "Returned: <pre>$output</pre>";

	//Attempted: "c:\supersalon\ssproject\scripts\rcl.exe" -c -u "dialup_username" -p "dialup_password"
