pg_close — Closes a PostgreSQL connection

Descrierea

pg_close ( resource $connection = ? ) : bool

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

Notă:
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 large object resource on the connection, do not close the connection before closing all large object resources.

Parametri

pg_close(...) will not technically close a persistent connection but instead returns it back to the connection pool thus giving you the desired effect of having the connection closed within your script.

This function closes the current database connection specified by a handle returned from a pg_connect() call.

<?php
    $pgsql_conn = pg_connect("dbname=mark host=localhost");

    if ($pgsql_conn) {
        print "Successfully connected to: " . pg_host($pgsql_conn) . "<br/>\n";
    } else {
        print pg_last_error($pgsql_conn);
        exit;
    }

    // Do database stuff here.

    if(!pg_close($pgsql_conn)) {
        print "Failed to close connection to " . pg_host($pgsql_conn) . ": " .
       pg_last_error($pgsql_conn) . "<br/>\n";
    } else {
        print "Successfully disconnected from database";
    }
?>

Of course you normally wouldn't print a message.
