and its showing me error

The localhost page isn’t working localhost is currently unable to handle this request. HTTP ERROR 500

Solution

first of all in IIS rub your simple PHP page

if it run successfully then run this code

<?php
phpinfo();
?> 

if you are not able to see oci8 driver in this page then search Oracle Instant Client for php http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html

also copy same DLL in system32 and system

then again restart IIS and then see in phpinfo() if oci8 driver display then

run this connection code
