    pg_close — Closes a PostgreSQL connection

    Açıklama

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

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

    Bilginize:

    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.

    Bağımsız Değişkenler

    connection

    PgSql\Connection nesnesi. bağlantı null ise, öntanımlı bağlantı kullanılır.Öntanımlı bağlantı pg_connect() veya pg_pconnect() işleviyle kurulmuş son bağlantıdır.

    Uyarı

    PHP 8.1.0 ve sonrasında, öntanımlı bağlantının kullanımı önerilmemektedir.

    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.

    best wishes to all.

    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.
