In this example, we are connecting to a database using mysqli_connect() and then using mysqli_query() to execute an UPDATE statement that modifies a record in the table. This method is commonly used in database applications to modify records based on user input or other event-driven actions. The Update_table method is part of the PHP MySQLi extension, which provides an object-oriented interface to the MySQL database server. This extension is included with PHP and does not require any additional libraries or packages to be installed.
