You may want to use exec first, so you can more easily capture the error
output and error codes.
exec("home/test.cgi $var", $output, $error);
if ($error){
//You should probably use error_log here in your real code...
//ASSUME this is going to break some day, for whatever reason.
//You'll need it logged unless you like dealing with error reports like:
//"Hey, the website broke yesterday."
echo "OS Error: $error<br />\n";
echo implode("<br />", $output);
exit;
}
echo $output;
Meanwhile, odds are *REALLY* good that you're not even calling the
test.cgi script because you haven't provide a path that PHP can use.
home/test.cgi would be assuming that home was in the same directory as
your PHP script, and even that is kinda iffy depending on where you do
this from the webserver or CLI...
I would recommend using FULL PATH to *everything* in exec (and passthru)
/full/path/to/home/test.cgi /full/path/to/any/args.txt
Also be sure to use the escapeshellargs function to make your $var data
kosher if it comes from the outside world.
