Yes, or how do you install Oracle extensions?
------ Solution --------------------
The manual is clearly written.

Requirement
The Oracle client library is required to use this extension. For Windows users, php_oci8.dll can be used only in libraries with a minimum version of 10.

The most convenient way to install all required files is to use the Oracle Instant Client. you can get it from: http://www.oracle.com/policy/tech/oci/instantclient/instantclient.html. To enable the OCI8 module to work, the "basic" version of Oracle Instant Client is sufficient. The Instant Client does not require ORACLE_SID or ORACLE_HOME environment variables to be set. However, you may still need to set LD_LIBRARY_PATH and NLS_LANG.

Before using this extension, make sure that the Oracle environment variables have been correctly set for Oracle users and web daemon users. These variables should be set before starting the web server. The environment variables to be set are listed below:


ORACLE_HOME

ORACLE_SID

LD_PRELOAD

LD_LIBRARY_PATH

NLS_LANG

For less-used Oracle environment variables such as TNS_ADMIN, TWO_TASK, ORA_TZFILE, and various Oracle global settings such as ORA_NLS33, ORA_NLS10, and NLS _ *, see Oracle stability.

After setting environment variables for web server users, you also need to add the web server user (nobody, www) to the oracle Group.
