Requirements
OCI8 3.0 is included with PHP 8. It is also available from » PECL. For
PHP 7, use OCI8 2.2 from » PECL. OCI8 requires Oracle
10g or later Oracle client libraries.
If the Oracle Database is on the same machine as PHP, the database software
already contains the necessary libraries and header files. When PHP is on a
different machine, use the free
» Oracle Instant Client libraries.
To use Oracle Instant Client, install the Basic
or Basic Light
Oracle Instant Client ZIP file, RPM
package, or DMG package. When building OCI8 from source code, also install
the Instant Client SDK
.
You must run PHP with the same, or a more recent, version of the
Oracle libraries that OCI8 was built with.
Note:
Oracle's standard client-server network interoperability allows connections
between different versions of Oracle Client and Oracle Database. For
certified configurations see Oracle Support's Doc ID 207303.1. In
summary, Oracle Client 19, 18 and 12.2 can connect to Oracle Database 11.2
or greater. Oracle Client 12.1 can connect to Oracle Database 10.2 or
greater. Oracle Client 11.2 can connect to Oracle Database 9.2 or greater.
Note:
Full OCI8 feature support is only available when using the most
recent versions of the Oracle client libraries and database.
