pg_lo_import — Import a large object from file

### Описание

int pg_lo_import ([ resource `$connection` ], string `$pathname` , mixed `$object_id` )

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.

`object_id`

  If an `object_id` is given the function will try to create a large object with this id, else a free object id is assigned by the server. The parameter was added in PHP 5.3 and relies on functionality that first appeared in PostgreSQL 8.1.

### Возвращаемые значения

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