The OCI8 1.4 extension is included with PHP 5.3,
PHP 5.4 and PHP 5.5. It is also available from » PECL. A newer OCI8 2.0 version is
available only from » PECL. OCI8 1.4 requires Oracle
10g or 9iR2
client libraries and will install on PHP 4.3.9 onwards. OCI8 2.0
requires Oracle 12c, 11g or 10g client libraries
and will install on PHP 5.2 onwards.
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
To use Oracle Instant Client, install the
basic or basiclite Oracle Instant Client ZIP file
or RPM package. When building PHP from source code, also install
the sdk ZIP file or devel RPM package.
You must run PHP with the same, or a more recent,
version of the Oracle libraries that OCI8 was built with.
On Windows, the php_oci8 DLL needs Oracle client
libraries from version 10gR2 or greater.
In PHP 5.3 up to and including PHP 5.3.5, the php_oci8_11g DLL
requires Oracle 11gR1 or greater client
libraries. From PHP 5.3.6 the php_oci8_11g DLL requires Oracle
11gR2 or greater client libraries. The
php_oci8_12c DLL from PECL requires Oracle 12cR1 client libraries. With some versions of Instant
Client you may additionally need mfc71.dll and msvcr71.dll libraries.
If OCI8 uses 9iR2 client
libraries, then PHP can connect to Oracle Database 8i, 9iR2, 10g or 11g. If OCI8 uses
10gR2 client libraries, the database can
be 9iR2, 10g,
11g or 12c. If
OCI8 uses 11g client libraries, the
database can be 9iR2, 10g, 11g or 12c. If OCI8 uses 12c
client libraries, the database can be 10gR2, 11g or 12c.
Full OCI8 feature support is only available when
using the most recent versions of the Oracle client libraries and
