pg_put_line — Send a NULL-terminated string to PostgreSQL backend

Description

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

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.
