    pg_lo_import — Import a large object from file

    Descripción

    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.

    Nota:

    This function used to be called pg_loimport().

    Parámetros

    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().

    Advertencia

    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.

    Valores devueltos

    The OID of the newly created large object, o false en caso de error.

    Historial de cambios
