PHP or Python for image manipulation?

Question

MySQL

Hi all.
I am more or less familiar with php (OOP, MVC) and worked with it for a couple of years, the task of working with images appeared, and specifically the recognition of certain shapes and processing them, subsequently issuing a new image based on what was recognized ...
Work as I think, with OpenCV, but most of the libraries, ready-made solutions, examples, etc., are given in python
And so I was faced with a choice, urgently learn Python and Django, or try to implement everything in PHP?
Please let me know if anyone has experience, I would be very grateful.

Answer 1

Classes (id, name)
Students (id, name, class_id)
Subjects (id, name)
Grades (student_id, subject_id, grade)
The grade table is also a link table Subjects <=> Students

Answer 2

Well, how would I do -
students.sql
| id | first_name | last_name | birthday (unix) | class (string) | well and on trifles |
| 999 | Dmitry | Grachev | 10/10/2001 | 9 A | well and on trifles |
--------------------------------
teachers.sql
--------------- -----------------
| id | first_name | last_name | birthday (unix) | well, little things
| 1024 | Tatyana | Eblova | 2131241412421 | yes
--------------------------------
assessments.sql
| id | student_id | evaluation | teacher_id | time
| 1 | 999 | 2 | 1024 | 13123123124
--------------------------------
Well, maybe it's somehow banal, well, I don't know, it'll do
