* Open database * @link http://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: * * DBA locking * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
