# The OCI8 Extension
|
|
|
|
Use the OCI8 extension to access Oracle Database.
|
|
|
|
Documentation is at https://www.php.net/oci8
|
|
|
|
Use `pecl install oci8` to install for PHP 8.
|
|
|
|
Use `pecl install oci8-2.2.0` to install for PHP 7.
|
|
|
|
Use `pecl install oci8-2.0.12` to install for PHP 5.2 - PHP 5.6.
|
|
|
|
Use `pecl install oci8-1.4.10` to install for PHP 4.3.9 - PHP 5.1.
|
|
|
|
The OCI8 extension can be linked with Oracle client libraries from Oracle
|
|
Database 10.2 or later. These libraries are found in your database
|
|
installation, or in the free Oracle Instant Client from
|
|
https://www.oracle.com/database/technologies/instant-client.html
|
|
Install the 'Basic' or 'Basic Light' Instant Client package. If building from
|
|
source, then also install the SDK package.
|
|
|
|
Oracle's standard cross-version connectivity applies. For example, PHP OCI8
|
|
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.
