$lastlinefromfunction = exec('limited by the console
command',$array_ofwholeoutput,$returnvaluefromconsolecommand);
In *nix world the console command returns either 0 or 1 (there are exemptions
where an error value is returned), depending if the function did execute
properly or not. $returnvaluefromconsolecommand
the exec() returns the last line from the command executed. $lastlinefromfunction
the $array_ofwholeoutput is the complete output from the command, first line
is $array_ofwholeoutput[0], next line is $array_ofwholeoutput[1] and so on.
This is quite well documented at the
http://www.php.net/manual/en/function.exec.php
What you put in between the single/double quotes depends on what you want to
do, and parameters for the console command depends which one you use, for more
info there you will need to use the manual page: man <command>
