Oracle Functions (PDO_OCI)

安装

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

预定义常量

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。
