pg_lo_import

(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

pg_lo_importImport a large object from file

Description

pg_lo_import(PgSql\Connection $connection = ?, string $pathname, mixed $object_id = ?): int

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.

Note:

This function used to be called pg_loimport().

Parameters

connection

An PgSql\Connection instance. When connection is unspecified, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

Warning

As of PHP 8.1.0, using the default connection is deprecated.

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 relies on functionality that first appeared in PostgreSQL 8.1.

Return Values

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

Changelog

Version Description
8.1.0 The connection parameter expects an PgSql\Connection instance now; previously, a resource was expected.

Examples
