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
