You should add "extension=oci8.so" to php.ini

4.Create /etc/php.d/oci8.ini

; Enable OCI8 extension module
extension=oci8.so

; Connection: Enables privileged connections using external
; credentials (OCI_SYSOPER, OCI_SYSDBA)

; Connection: The maximum number of persistent OCI8 connections per
; process. Using -1 means no limit.
;oci8.max_persistent = -1

; Connection: The maximum number of seconds a process is allowed to
; maintain an idle persistent connection. Using -1 means idle
; persistent connections will be maintained forever.
;oci8.persistent_timeout = -1

; Connection: The number of seconds that must pass before issuing a
; ping during oci_pconnect() to check the connection validity. When
; set to 0, each oci_pconnect() will cause a ping. Using -1 disables
; pings completely.
;oci8.ping_interval = 60

; Connection: Set this to a user chosen connection class to be used
; for all pooled server requests with Oracle 11g Database Resident
; Connection Pooling (DRCP).  To use DRCP, this value should be set to
; the same string for all web servers running the same application,
; the database pool must be configured, and the connection string must
; specify to use a pooled server.

; High Availability: Using On lets PHP receive Fast Application
; Notification (FAN) events generated when a database node fails. The

; many statements to cache. Using 0 disables statement caching.

; Compatibility. Using On means oci_close() will not close
; oci_connect() and oci_new_connect() connections.
