lob_identifier: Lob identifier as a result of cubrid_lob2_new() or get from the result set.
buf: Data that need to be written to the lob object.

返回值

成功时返回 true，或者在失败时返回 false。

示例 #1 cubrid_lob2_write() example 1


<?php
// test_lob (id INT, contents CLOB)

$lob = cubrid_lob2_new($conn, 'CLOB');
$len = cubrid_lob2_write($lob, "Hello world");

cubrid_lob2_bind($req, 1, $lob);
