There are two resource types used in the MySQL module. The first one
|
|
is the link identifier for a database connection, the second a resource
|
|
which holds the result of a query.

Most MySQL functions accept <parameter>link_identifier</parameter> as
|
|
the last optional parameter. If it is not provided, last opened
|
|
connection is used. If it doesn't exist, connection is tried to
|
|
establish with default parameters defined in &php.ini;. If it is not
|
|
successful, functions return &false;.
