I have a php script running on centos 5.x When i use a code like

$db->connect();

php script doesn't work.I use php myscript.php and it does nothing. .. .. ..

$db->connect();
echo "Hello world";

when i run above script it does nothing.Nothing means the like this; [root@xxxxxxx update_call_history]# php update_call_history.php {press enter} [root@xxxxxxx update_call_history]#

ama böyle senaryoyu değiştirirseniz

echo "hello world";

it works.I think my php doesnt run class structured script,Is there any missing module or what. Thanks for advance...
