* Open database
* @link https://php.net/manual/en/function.dba-open.php
* @param string $path <p>
* Commonly a regular path in your filesystem.
* </p>
* @param string $mode <p>
* 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.
* </p>
* <p>
* 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.
* </p>
* <p>
* 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.
* </p>
* <p>
* 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>
