pg_put_line — Send a NULL-terminated string to PostgreSQL backend
$connection
], string $data
) : boolpg_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().
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
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().
dataA line of text to be sent directly to the PostgreSQL backend. A NULL terminator is added automatically.
Returns TRUE on success or FALSE on failure.
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);
?>
