exec() output does not print but shows up on command line

[ppowell]

   	$msg = exec("nslookup -retry=4 -timeout=2 -type=mx $host 2>&1"); // $host is an email server domain
	echo "results for \"nslookup -retry=4 -timeout=2 -type=mx $host\": " . $msg . " and that is all\n<P><P>";

I am trying to do an MX NSLOOKUP via PHP and while this works via command line with no problem, I am unable to reproduce the results via browser. Any thoughts?

Thanx
Phil

Try using a function that returns the entire output as a string, such as [man]shell_exec/man.
