Available DBA handlers

function listDBA() {
    echo "Available DBA handlers:<br>";
    foreach (dba_handlers(true) as $handler_name => $handler_version) {
        // clean the versions
        $handler_version = str_replace('$', '', $handler_version);
        echo " - $handler_name: $handler_version<br>";
    }
}

Here is output on my PC
