The PDO_OCI Extension

Use the PDO_OCI extension to access Oracle Database via PHP Data Objects (PDO) APIs.

This repository is for PHP 8.3+ as it was decided to unbundle PDO OCI / OCI8 extension from the PHP source code.

Documentation is at https://www.php.net/pdo_oci

Installation

Use pecl install pdo_oci to install for PHP 8.3 and newer versions.

For older PHP versions, use php_pdo_oci.dll from the Windows PHP release bundle, or build from the PHP source code by running:

phpize
./configure --with-pdo_oci=shared,instantclient,/path/to/instant/client/sdk/lib
make install

To complete installation, add "extension=pdo_oci.so" or "extension=php_pdo_oci.dll" (Windows) to your php.ini file.

Additional Requirements

The PDO_OCI extension can be linked with Oracle Client libraries from Oracle Database 11.2 or later. These libraries are found in your database installation, or in the free Oracle Instant Client packages from https://www.oracle.com/database/technologies/instant-client.html. Install the 'Basic' or 'Basic Light' Instant Client package for running applications with this extension. If building from source, then also install the Instant Client SDK package.

Oracle's standard cross-version connectivity applies. For example, PHP PDO_OCI linked with Instant Client 19c can connect to Oracle Database 11.2 onward. See Oracle's note "Oracle Client / Server Interoperability Support" (ID 207303.1) for details.
