pg_lo_import

(PHP 4 >= 4.2.0, PHP 5)

pg_lo_import — Import a large object from file

Описание

int pg_lo_import ( resource $connection , string $pathname )
int pg_lo_import ( string $pathname )

pg_lo_import() creates a new large object in the database using a file on the filesystem as its data source.

To use the large object interface, it is necessary to enclose it within a transaction block.

Замечание: Когда опция safe mode включена, PHP проверяет, имеют ли файлы/каталоги, с которыми вы собираетесь работать, такой же UID (владельца), как и выполняемый скрипт.

Замечание: This function used to be called pg_loimport().

Список параметров

connection

PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

pathname

The full path and file name of the file on the client filesystem from which to read the large object data.

Возвращаемые значения

The OID of the newly created large object, or FALSE on failure.

it works for me (php-4.2.1)

not like this

int pg_lo_import ( string pathname [, resource connection])

but 
int pg_lo_import ( resource connection, string pathname )

don't know the reason

Due to a bug, PHP 4.2.0 and 4.2.1 does not support pg_lo_import() old API. It's fixed in PHP 4.2.2.

BTW, new API will be always available from PHP 4.2.0 to later versions. Older API will be kept long enough, also.

Due to a bug, OLD API does not available with PHP 4.2.0 and 4.2.1.

PHP 4.2.2 will support OLD API again and will be kept long enough.

New API will be available PHP 4.2.0 to later versions.

Автор:
its not very clear if pg_lo_import needs to have pg_lo_open called first. Because pg_lo_import handles the process of writign to the file, it seems logical that pg_lo_open does not need to be called. However due to the ugly nature of how postgres handles oid objects, it would be nice to have this documented.
