pg_lo_import — 將文件導入為大型對象
說明
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.
要使用大型對象（lo）接口，需要將其放置在事務塊中。
Note: 當啟用 安全模式時， PHP 會檢查被操作的文件或目錄是否與被執(zhí)行的腳本有相同的 UID（所有者）。
Note:
本函數(shù)以前的名字為 pg_loimport()。
參數(shù)
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
變量指明了要導入為大型對象的文件名。
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.
返回值
導入成功則返回新建的大型對象的 OID，如果出錯則返回 FALSE。
更新日志
版本 說明 5.3.0
The optional object_id was added.
在 PHP 4.2.0 版本之前，本函數(shù)語法不一樣，見如下定義：
int pg_lo_import
( string $pathname
[, resource $connection
] )
范例
Example #1 pg_lo_import() 例子
<?php
$database = pg_connect("dbname=jacarta");
pg_query($database, "begin");
$oid = pg_lo_import($database, '/tmp/lob.dat');
pg_query($database, "commit");
?>
