pg_close

(PHP 4, PHP 5, PHP 7, PHP 8)

pg_close — Closes a PostgreSQL connection

pg_close(?PgSql\Connection$connection = null): true

pg_close() closes the non-persistent connection to a PostgreSQL database associated with the given connection instance.

Note:
Using pg_close() is not usually necessary, as non-persistent open connections are automatically closed at the end of the script.

If there is open PgSql\Lob instance on the connection, do not close the connection before closing all PgSql\Lob instances.

connection: An PgSql\Connection instance. When connection is null, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().
Warning
As of PHP 8.1.0, using the default connection is deprecated.

Always returns true.

Version	Description
8.2.0	The return type is `true` now; previously, it was bool.
8.1.0	The `connection` parameter expects an PgSql\Connection instance now; previously, a resource was expected.
8.0.0	`connection` is now nullable.
