This article introduces the PHP simple complaint page implementation code, share for everyone to reference, the specific content as follows

<?php/* Design mode Practice * 1. Database connection Class (single case mode) * 2. Call the interface to implement the function of the message (Factory mode) * 3. Implement the Classification report processing function (responsibility chain mode) * 4. Send different combinations of reporting information (bridging mode) * 5. Send different formats Report information (adapter mode) * 6. Automatically append time after complaint content (adorner mode) * 7. According to the member login information to change the display style (Observer mode) * 8. According to the posting length plus experience value (policy mode) * * * interface DB {function con
