Based on your corrected code in your own reply, which lists the second
line as "echo $response;", I can see what you problem would be.

Even if you're allowed to run this particular command from your PHP
script, the return value of exec() is always the LAST line of the command
output. On my system, the last line of the "ifconfig" command is always
blank, which is what $response in your code example would contain. Try
instead to do it like this (and, preferrably, include the full path of
ifconfig):

exec('/sbin/ifconfig', $response); // $response is an array
echo implode('\n', $response);
