To be able to access Oracle databases from PHP, you will need to have PHP compiled / linked with the Oracle OCI (oci8) library.
You could use the pre-built PHP 5 from Zend or there are two other ways to get PHP working with OCI8:
- Install the Oracle Database [Oracle10g] [Oracle9i]
- Install Oracle Instant Client
If your Oracle database is in another machine, the Oracle Instant Client is a smaller install.
PHP using Oracle Database Server

PHP using Oracle Instant Client
Tested Environments:
- Ubuntu Server 10.04 LTS
- Oracle Instant Client 11.2
- Ubuntu 11.04 x64
- Oracle Instant Client 11.2
Prerequisites:
sudo apt-get install build-essential sudo apt-get install php5-dev php-pear libaio1
Instant Client installation requires some environment variables to be able to see the library folder. Edit /etc/environment and add at the end:
# Oracle Instant Client LD_LIBRARY_PATH="/usr/local/lib/instantclient_11_2" TNS_ADMIN="/usr/local/lib/instantclient_11_2" ORACLE_BASE="/usr/local/lib/instantclient_11_2" ORACLE_HOME=$ORACLE_BASE
Then download the Oracle Instant Client from Oracle (you will need to create an account).
You will need the Basic (48MB) and SDK (600K). The Basic Lite version does not work.
cd /usr/local/lib sudo unzip <location-of-instant-client-basic> sudo unzip <location-of-instant-client-sdk> cd instantclient_11_2 sudo ln -s libclntsh.so.11.1 libclntsh.so
The symbolic link is needed during the compilation step later.
sudo pecl install oci8
You will be prompted for the location of the library:
instantclient,/usr/local/lib/instantclient_11_2
You will be prompted also for the ORACLE_HOME location, type 'all', accept and then insert:
instantclient,/usr/local/lib/instantclient_11_2
PHP5 Instructions
You should now create a new oci8.ini file which will be included when loading php.ini (Editing the php.ini is discouraged):
nano /etc/php5/conf.d/oci8.ini
this will create a blank file; add to this file:
extension=oci8.so
Old Instructions (Maybe PHP4)
If successful, you may now add the following line at the bottom of php.ini
extension=oci8.so
The php.ini is found in 2 places: /etc/php5/apache2/php.ini and /etc/php5/cli/php.ini
sudo /etc/init.d/apache2 reload
Check <?php echo phpinfo() ?> to verify if the oci8 module is available.
