pg_put_line -- Send a NULL-terminated string to PostgreSQL backend
Description
bool pg_put_line ( string data ) 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().
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.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
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); ?>
