exec and system do not work

[Ethan Rosenberg <erosenberg@xxxxxxxxxxxxxxxxxxxx>]

Dear List -

I'm lost on this one -

This works -

$out = system("ls -l ",$retvals);
printf("%s", $out);

This does -

echo exec("ls -l");

This does not -

if( !file_exists("/var/www/orders.txt"));
{
   $out = system("touch /var/www/orders.txt", $ret);
   $out2 = system("chmod 766 /var/www/orders.txt", $ret);
   echo 'file2<br />';
   echo file_exists("/var/www/orders.txt");
}

and this does not -

if( !file_exists("/var/www/orders.txt"));
{
   exec("touch /var/www/orders.txt");
   exec("chmod 766 /var/www/orders.txt");
   echo 'file2<br />';
   echo file_exists("/var/www/orders.txt");
}

Ethan
