Question

I’m trying to implement a CRUD interface for the IP routing tables and I’m stuck at executing unix commands with PHP.
I’ve tried to echo the output for the route command using shell_exec command but the output is null.

echo shell_exec("route"); // Outputs nothing

I’ve also tried several other combinations like:

echo exec("route"); // also outputs nothing
// and
$lastLine = system("route", $output);
echo $lastLine; // nothing
echo $output; // 127

So, how should I execute the route command from PHP?

Thanks!

Answer 1

Try first from console

whereis route

Then execute route command with full path

Basically, i think, it because of PATH env is not include /sbin:
