/**
 * Open database
 * @link https://php.net/manual/en/function.dba-open.php
 * @param string $path 
 * Commonly a regular path in your filesystem.
 * 
 * @param string $mode 
 * It is r for read access, w for
 * read/write access to an already existing database, c
 * for read/write access and database creation if it doesn't currently exist,
 * and n for create, truncate and read/write access.
 * The database is created in BTree mode, other modes (like Hash or Queue)
 * are not supported.
 * 
 * 
 * Additionally you can set the database lock method with the next char.
 * Use l to lock the database with a .lck
 * file or d to lock the databasefile itself. It is
 * important that all of your applications do this consistently.
 * 
 * 
 * If you want to test the access and do not want to wait for the lock
 * you can add t as third character. When you are
 * absolutely sure that you do not require database locking you can do
 * so by using - instead of l or
 * d. When none of d,
 * l or - is used, dba will lock
 * on the database file as it would with d.
 * 
 * 
 * There can only be one writer for one database file. When you use dba on
 * a web server and more than one request requires write operations they can
 * only be done one after another. Also read during write is not allowed.
 * The dba extension uses locks to prevent this. See the following table:
 * <table>
 * DBA locking
 * <tr valign="top">
 * <td>already open</td>
 * <td>mode = "rl"</td>
 * <td>mode = "rlt"</td>
 * <td>mode = "wl"</td>
