dbx_connect — Open a connection/database
Opens a connection to a database.
moduleparameter can be either a string or a constant, though the latter form is preferred. The possible values are given below, but keep in mind that they only work if the module is actually loaded.
The SQL server host
The database name
persistentparameter can be set to
DBX_PERSISTENT, if so, a persistent connection will be created.
parameters are expected, but not always used depending on the connect
functions for the abstracted module.
Returns an object on success,
FALSE on error. If a connection has been
made but the database could not be selected, the connection is closed and
FALSE is returned.
The returned object has three properties:
- It is the name of the currently selected database.
It is a valid handle for the connected database, and as such it can be used in module-specific functions (if required).
$link = dbx_connect(DBX_MYSQL, "localhost", "db", "username", "password");
mysql_close($link->handle); // dbx_close($link) would be better here
- It is used internally by dbx only, and is actually the module number mentioned above.
Example #1 dbx_connect() example
$link = dbx_connect(DBX_ODBC, "", "db", "username", "password", DBX_PERSISTENT)
or die("Could not connect");
echo "Connected successfully";
Always refer to the module-specific documentation as well.
