pg_put_line — Send a NULL-terminated string to PostgreSQL backend
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.
Nota:
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().
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.
connection
Uma instância de PgSql\Connection.
Quando o parâmetro connection
não for especificado, a conexão padrão será usada.
A conexão padrão é a última conexão feita por pg_connect()
ou pg_pconnect().
A partir do PHP 8.1.0, usar a conexão padrão tornou-se defasado.
data
A line of text to be sent directly to the PostgreSQL backend. A NULL
terminator is added automatically.
Versão | Descrição |

8.1.0 |
O parâmetro connection agora espera uma instância de PgSql\Connection;
anteriormente, um resource era esperado.

Exemplo #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);
