In Ubuntu 16.04, using PHP 5.6, with 64bit os, try this:

Install the packages:

sudo apt-get install php5.6-dev build-essential php-pear libaio1

Download the latest version of the packages from:

http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

Search for these packages, according with the latest version:

oracle-instantclientXX.X-basic-XX.X.X.X.X-X.x86_64.rpm
oracle-instantclientXX.X-devel-XX.X.X.X.X-X.x86_64.rpm

Converting packages:

sudo apt-get install alien
sudo alien oracle-instantclientXX.X-basic-XX.X.X.X.X-X.x86_64.rpm
sudo alien oracle-instantclientXX.X-devel-XX.X.X.X.X-X.x86_64.rpm

Installing:

sudo dpkg -i oracle-instantclientXX.X-basic_XX.X.X.X.X-X_amd64.deb
sudo dpkg -i oracle-instantclientXX.X-devel_XX.X.X.X.X-X_amd64.deb

Installing oci8:

sudo pecl install oci8-2.0.12

*Build process completed successfully
Installing '/usr/lib/php/20131226/oci8.so'
install ok: channel://pecl.php.net/oci8-2.0.12
configuration option "php_ini" is not set to php.ini location
You should add "extension=oci8.so" to php.ini*

Add the extension to php:

sudo gedit /etc/php/5.6/apache2/php.ini

add the extension:

extension=oci8.so

Restart apache:

sudo service apache2 restart

That's it.
