pg_put_line

pg_put_line

(PHP 4 >= 4.0.3, PHP 5)

pg_put_line向 PostgreSQL 后端发送以 NULL 结尾的字符串

说明

bool pg_put_line ([ resource $connection ], string $data )

pg_put_line() 向 PostgreSQL 后端服务器发送以 NULL 结尾的字符串。例如可以通过 PostgreSQL 的 copy 操作来向表中高速插入数据。结尾的 NULL 字符会自动加入。成功时返回 TRUE, 或者在失败时返回 FALSE.

Note:

应用程序必须明确地在最后一行发送两个字符 "." 来向后端指明发送数据结束。

Example #1 向表中高速插入数据

<?php 
    $conn 
pg_pconnect ("dbname=foo");
    
pg_query($conn"create table bar (a int4, b char(16), d float8)");
    
pg_query($conn"copy bar from stdin");
    
pg_put_line($conn"3 hello world 4.5 ");
    
pg_put_line($conn"4 goodbye world 7.11 ");
    
pg_put_line($conn"\. ");
    
pg_end_copy($conn);
?>
