pg_close

Closes a PostgreSQL connection

Description

true pg_close(PgSql\Connectionnull $connection = null)

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.

Parameters

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.

Return Values

Always returns true.

Changelog

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.
