First step: Install the Oracle Client

1. Download Instant Client from http://www.oracle.com/technetwork/indexes/downloads/index.html#database (you must be registered in Oracle; it's free). You will need instantclient-basic-*-*.zip and instantclient-sdk-*-*.zip files.

2. Execute the following commands in your terminal:

   $ sudo su -  
   $ mkdir -p /opt/oracle/instantclient
   $ cd /opt/oracle/instantclient

3. Copy downloaded files into /opt/oracle/instantclient.

4. Unzip files executing these commands:

   $ unzip instantclient-basic-*-*.zip
   $ unzip instantclient-sdk-*-*.zip

5. Move all /opt/oracle/instantclient/instantclient content to /opt/oracle/instantclient:

   $ mv instantclient*/* ./
   $ rmdir instantclient*/

6. During extension compiling, some errors will arise when linking with some libraries. To avoid them, do:

   $ ln -s libclntsh.so.* libclntsh.so
   $ ln -s libocci.so.* libocci.so
   $ echo /opt/oracle/instantclient >> /etc/ld.so.conf
   $ ldconfig

7. Create a folder for your network configuration files:

   $ mkdir -p network/admin

8. Place sqlnet.ora and tnsnames.ora files in /opt/oracle/instantclient/network/admin.

Now you have the basic connection kit for connections and SDK for compiling PHP extensions.

Second step: Install the OCI8 PHP Extension

1. Get all essential packages for download and compiling from PEAR repositories:

   $ apt-get install --yes php5 php5-cli php5-dev php-db php-pear
   $ apt-get install --yes build-essential libaio1

2. Request OCI8 install:

   $ pecl install oci8

   Type instantclient,/opt/oracle/instantclient when prompted for Instant Client path.

3. Save this text in /etc/php5/mods-available/oci8.ini:

   extension=oci8.so

4. Activate extension:

   $ php5enmod oci8

Now you have all oci_* functions available for PHP in both php-cli and Apache.

Third step: Install the PDO/OCI PHP Extension

The pdo_oci library is outdated, so its install is more tricky.

1. Fix paths:

   $ cd /usr/include/
   $ ln -s php5 php
   $ cd /opt/oracle/instantclient
   $ mkdir -p include/oracle/11.1/
   $ cd include/oracle/11.1/
   $ ln -s ../../../sdk/include client
   $ cd -
   $ mkdir -p lib/oracle/11.1/client
   $ cd lib/oracle/11.1/client
   $ ln -s ../../../../ lib
   $ cd -

2. Download pdo_oci via pecl:

   $ pecl channel-update pear.php.net
   $ mkdir -p /tmp/pear/download/
   $ cd /tmp/pear/download/
   $ pecl download pdo_oci

3. Extract source:

   $ tar xvf PDO_OCI*.tgz
   $ cd PDO_OCI*

4. Create a file named config.m4.patch:

   *** config.m4	2005-09-24 17:23:24.000000000 -0600
   --- /home/myuser/Desktop/PDO_OCI-1.0/config.m4	2009-07-07 17:32:14.000000000 -0600
   ***************
   *** 7,12 ****
   --- 7,14 ----
       if test -s "$PDO_OCI_DIR/orainst/unix.rgs"; then
         PDO_OCI_VERSION=`grep '"ocommon"' $PDO_OCI_DIR/orainst/unix.rgs | sed 's/[ ][ ]*/:/g' | cut -d: -f 6 | cut -c 2-4`
         test -z "$PDO_OCI_VERSION" && PDO_OCI_VERSION=7.3
   +   elif test -f $PDO_OCI_DIR/lib/libclntsh.$SHLIB_SUFFIX_NAME.11.1; then
   +     PDO_OCI_VERSION=11.1    
       elif test -f $PDO_OCI_DIR/lib/libclntsh.$SHLIB_SUFFIX_NAME.10.1; then
         PDO_OCI_VERSION=10.1    
       elif test -f $PDO_OCI_DIR/lib/libclntsh.$SHLIB_SUFFIX_NAME.9.0; then
   ***************
   *** 119,124 ****
   --- 121,129 ----
         10.2)
           PHP_ADD_LIBRARY(clntsh, 1, PDO_OCI_SHARED_LIBADD)
           ;;
   +     11.1)
   +       PHP_ADD_LIBRARY(clntsh, 1, PDO_OCI_SHARED_LIBADD)
   +       ;;
         *)
           AC_MSG_ERROR(Unsupported Oracle version! $PDO_OCI_VERSION)
           ;;
   #EOF
   

5. Apply patch:

   $ patch --dry-run -i config.m4.patch && patch -i config.m4.patch && phpize

6. Replace all references of function_entry to zend_function_entry in pdo_oci.c.

7. Configure, compile and install:

   $ ORACLE_HOME=/opt/oracle/instantclient ./configure --with-pdo-oci=instantclient,/opt/oracle/instantclient,11.1
   $ make && make test && make install && mv modules/pdo_oci.so /usr/lib/php5/*+lfs/

8. Save this text in /etc/php5/mods-available/pdo_oci.ini:

   extension=pdo_oci.so

9. Activate extension:

   $ php5enmod pdo_oci

And now you can take a cup of coffee.
