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 libraries. For details refer to the OCI8 Requirements section.
Use --with-pdo-oci[=DIR] to install the PDO Oracle OCI extension, where the optional [=DIR] is the Oracle Home directory. [=DIR] defaults to the $ORACLE_HOME environment variable.
Use --with-pdo-oci=instantclient,prefix,version for an Oracle Instant Client SDK, where prefix and version are configured.
// Using $ORACLE_HOME $ ./configure --with-pdo-oci // Using OIC for Linux with 10.2.0.3 RPMs with a /usr prefix $ ./configure --with-pdo-oci=instantclient,/usr,10.2.0.3
下列常量由此驱动定义，且仅在扩展编译入 PHP
或在运行时动态载入时可用。另外，使用此驱动时，仅会使用这些驱动特定的常量。使用其他驱动的驱动特定的常量可能会导致不可预见的情况。如果代码可运行于多个驱动，PDO::getAttribute()
可被用于获取
PDO_ATTR_DRIVER_NAME
属性以检查驱动。
