Web Database Architectures• A user’s Web browser issues an HTTP request. • The Web Server receives the request for results.php and
passes it to the PHP engine for processing• The PHP engine opens a connection to the MySQL DBMS
and sends the query.• The MySQL DBMS process the query and sends the results
back to the PHP engine.• The PHP engine formats the results in HTML and sends it
to the Web Server• The Web Servers passes the HTML page back to the user’s
browser
