PDO_PGSQL is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to PostgreSQL databases.
This extension defines a stream resource returned by PDO::pgsqlLOBOpen().
Use --with-pdo-pgsql[=DIR] to install
the PDO PostgreSQL extension, where the optional [=DIR]
is the PostgreSQL base install directory, or the path to pg_config.
$ ./configure --with-pdo-pgsql
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。
注意:
bytea
fields are returned as streams.
