To access an Oracle database from PHP, you must first install and properly configure the Oracle client software on the machine running PHP. The Oracle client is on most Oracle CDs. Ask your Oracle DBA for assistance on installing and configuring the software.

To use the OCI*() functions, you must load the php_oci8.dll extension by including a line the like following in your php.ini:

extension=php_oci8.dll

To use the out-of-date ORA_*() functions, you must load the php_oracle.dll extension by including a line like the following in your php.ini:

extension=php_oracle.dll

If you can't find php_oci8.dll or php_oracle.dll on your system, then you should download a fresh copy of PHP from http://www.php.net/
