pg_close - Closes a PostgreSQL connection
Manual
pg_close(
[PgSql\Connection|null$connection = null] ): bool
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.
