A related question about system development

A question about system development recently I just learned the analysis and design methods of system development, mainly structured development methods and object-oriented development methods. Now I am preparing to write my homework at the end of the period. I plan to use a structured development method to analyze the requirements and design the system. What are the data flowcharts, module structure charts, and so on. You don't need to comment on whether I should adopt structured or object-oriented. A question about system development
Recently I just learned the analysis and design methods of system development, mainly structured development methods and object-oriented development methods.
Now I am preparing to write my homework at the end of the period. I plan to use a structured development method to analyze the requirements and design the system. What are the data flowcharts, module structure charts, and so on. You don't need to comment on whether I should adopt structured or object-oriented.
My problem now is that I plan to use PHP to make my analysis and design into a complete system, but I don't know how to start now, even if the system design is complete, how can I convert the structured design into code? How can I organize code?
Another problem is that I don't know much about the system design methods and the patterns in PHP (such as MVC, zend Framwork ......) What is the relationship?
