1. From http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxsoft.html download instantclient-basic and instantclient-sdk for your system, e.g. "instantclient-basic-linux32-11.2.0.1.zip" and "instantclient-sdk-linux32-11.2.0.1.zip".

2. Unzip it into /opt/oracle/instantclient/, your have to get the follow structure:

3. Note there are two symlink: libclntsh.so -> libclntsh.so.11.1 and libocci.so -> libocci.so.11.1

4. Download PDO_OCI
cd /tmp
pecl download pdo_oci
tar xvfz PDO_OCI-1.0.tgz

5. Create /tmp/PDO_OCI-1.0/patch.txt with follow content (without empty line at the end):

6. Apply patch
cd /tmp/PDO_OCI-1.0
patch -p0 < /tmp/PDO_OCI-1.0/patch.txt

7. Continue PDO_OCI compliling
sudo phpize
sudo ./configure --with-pdo-oci=instantclient,/opt/oracle/instantclient,11.1
--with-oci8=instantclient,/opt/oracle/instantclient,11.1
sudo make
sudo make install

8. Add system variables:
export LD_LIBRARY_PATH="/opt/oracle/instantclient"
export ORACLE_HOME="/opt/oracle/instantclient"

9. Restart Apache or FCGI daemon
