[PHP] system() Question
Hello all,
I am using system to convert some files using a binary in linux. My code
looks like this:
$response = system('gpsbabel -p -r -t -i gpx -f test.gpx -o kml -F
test2.kml', $retval);
echo pResponse: , $response, /ppReturn Value: , $retval;
The $retval is returning code 127 - Any ideas on why this?
Thanks!

you might try shell_exec() instead to see if you can get any more mileage.
the return value of shell_exec() is the output of the executed command.

You overlooked the ampersand in front of $retval. The syntax for
'system' is:
string system ( string $command [, int $return_var ] )
You have to pass a pointer to the variable, not the variable itself.

Actually, that's not entirely correct while the documentation
shows it as a reference variable, it's not actually required to be a
pointer. And in either case, the OP had the error code returned
(127), and $retval would have nothing to do with causing the error.
What I would recommend trying is:
?php
exec('./gpsbabel -p -r -t -i gpx -f test.gpx -o kml -F
test2.kml 21',$ret);
print_r($ret);
?
On a side note, I'm curious as to what 'gpsbabel' does. I've
worked a bit with Keyhole markups and GIS overlays, etc. Neat stuff.
