Oracle PDO Driver (PDO_OCI)

Installation

If the Oracle Database is on the same machine as PHP, the database software already contains the necessary libraries. When PHP is on a different machine, use the free » Oracle Instant Client libraries. For details refer to the OCI8 Requirements section.

PHP 8.4

This extension has been moved to the » PECL repository and is no longer bundled with PHP as of PHP 8.4.0

Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: » https://pecl.php.net/package/PDO_OCI.

PHP < 8.4

Use --with-pdo-oci[=DIR] to install the PDO Oracle OCI extension, where the optional [=DIR] is the Oracle Home directory. [=DIR] defaults to the $ORACLE_HOME environment variable.

Use --with-pdo-oci=instantclient,prefix,version for an Oracle Instant Client SDK, where prefix and version are configured. 

// Using $ORACLE_HOME
$ ./configure --with-pdo-oci

// Using OIC for Linux with 10.2.0.3 RPMs with a /usr prefix
$ ./configure --with-pdo-oci=instantclient,/usr,10.2.0.3

Predefined Constants

The constants below are defined by this driver, and will only be available when the extension has been either compiled into PHP or dynamically loaded at runtime. In addition, these driver-specific constants should only be used if you are using this driver. Using driver-specific attributes with another driver may result in unexpected behaviour. PDO::getAttribute() may be used to obtain the PDO::ATTR_DRIVER_NAME attribute to check the driver, if your code can run against multiple drivers.
