PHP dynamic form generation and submission solutions

Generation and submission of dynamic PHP forms
Dear Brothers:
I have a requirement that the number of elements in the form is indeterminate (generated according to the needs of the program), and I now think of a way to generate these elements in terms of aspects, and the aspects of the form submitted after parsing, I initially estimated that there are two problems:
First, the name of the form element,
Second, the analysis of the form after submission

Learned PHP one day, spent a week, in this respect is absolutely rookie, thank you.

Thinking right. But sometimes it is possible to consider the nature of the problem of "indefinite number of elements", which may be replaced by a better alternative, of course, depending on the specific requirements.
