[PHP-DOC] Help with command system and argument htpasswd

[Ing. Oswaldo Peņaloza C.]

I use the next command
+---------------
if (system("/usr/bin/htpasswd -b /home/var/key_file $user1 $clave1")) {
echo "Update File"; } else {
echo "Error !!"; }
+-----------------
This work very good in other system (RedHat 7.2), but don't understand why
don't work in my new server Linux Redhat ver 9.0 with PHP 4.2.2 and Apache
2.0.
