running command from PHP

[Anon]

Hi. I am trying to run the /usr/sbin/postalias command using php giving it the options of hash:aliases so the command looks like:

/usr/sbin/postalias hash:aliases

I have tried using the popen() funtion but this seems not to do anything. I have it setup like this

$prog = popen("/usr/sbin/postalias hash:aliases" , "r");
$fclose($prog);

I know that the file permissions are correct for the aliases file. Any thoughts on how to do this differently or what I am doing wrong??

 Thanks

Try:

exec("/usr/sbin/postalias hash:aliases", $results);

The $results will be an array of lines that are returned after executing the command. One other thing to note is make sure that the user nobody(or whoever the webserver is running as) has execute perms for that file.
Hope that helps!
