I am trying to get the SSID from a Linux machine with PHP, but with shell_exec values between quotes seem to be ignored.

In the cli the result of iwgetid is:

wlan0     ESSID:"test"

However if I do the same with PHP using shell_exec:

$ssidInfo = shell_exec("iwgetid");

I get the following result:

wlan0     ESSID:

Is there a way to work around this?

I think `iwgetid` has to be run by root. What user is running the PHP script? – Barmar Sep 17 '15 at 04:37
When you tried it in the CLI, were you running as root? Does it work in the CLI as an ordinary user? – Barmar Sep 17 '15 at 04:42
When I change user to www-data in cli it still seems to work: sudo su - www-data $ iwgetid wlan0 ESSID:"test" – Gerard van den Bosch Sep 17 '15 at 04:46

How are you displaying `$ssidInfo`? – Barmar Sep 17 '15 at 04:47
The web page I found that said it required root was 5 years old, it may have changed since then. – Barmar Sep 17 '15 at 04:48
"How are you displaying $ssidInfo?" This was the golden pointer, my framework view seems to filter it away, when I simply echo it is there. Thank you for your assistance :) – Gerard van den Bosch Sep 17 '15 at 04:59
