PHP Development Online Questionnaire Use PHP to develop an online questionnaire (there is an option for normal or abnormal). The function I want to achieve is that after submitting the questionnaire, the abnormal questions will be displayed on the interface after submission, and the 2D scan will be scanned again on the same day. The code will only display the interface after submission. The filled-in content is valid on that day and can be filled in again the next day. Please give me the complete code, please give me some guidance
