require_once 'DB.php'; $db = DB::connect('mysql://username:password@localhost/database'); if (DB::isError($db)) { die("Error connecting to database: " . $db->getMessage()); }

$mydata = array('field1' => 'value1', 'field2' => 'value2', 'field3' => 'value3'); $db->autoExecute('mytable', $mydata, DB_AUTOQUERY_INSERT); if (DB::isError($db)) { die("Error inserting data: " . $db->getMessage()); }In these examples, we are using the PEAR DB package library, which is a popular choice for PHP developers. However, there are other database abstraction libraries available for PHP, such as PDO and mysqli. These libraries offer similar functionality to PHP DB, but may use a different syntax or method of connecting to databases.
