# pg_put_line

(PHP 4 >= 4.0.3, PHP 5)

pg_put_line — Send a NULL-terminated string to PostgreSQL backend

### 설명

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

pg_put_line() sends a NULL-terminated string to the PostgreSQL backend server. This is needed in conjunction with PostgreSQL's COPY FROM command.

COPY is a high-speed data loading interface supported by PostgreSQL. Data is passed in without being parsed, and in a single transaction.

An alternative to using raw pg_put_line() commands is to use pg_copy_from(). This is a far simpler interface.

> Note: The application must explicitly send the two characters "\." on the last line to indicate to the backend that it has finished sending its data, before issuing pg_end_copy().

Warning

Use of the pg_put_line() causes most large object operations, including pg_lo_read() and pg_lo_tell(), to subsequently fail. You can use pg_copy_from() and pg_copy_to() instead.

### 인수

`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().

`data`

  A line of text to be sent directly to the PostgreSQL backend. A NULL terminator is added automatically.

### 반환값

성공할 경우 `TRUE`를, 실패할 경우 `FALSE`를 반환합니다.

### 예제

Example #1 pg_put_line() example

`<?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\thello world\t4.5\n");
pg_put_line($conn, "4\tgoodbye world\t7.11\n");
pg_put_line($conn, "\\.\n");
pg_end_copy($conn);
?>`
