I have limited knowledge in PHP. So, I'm seeking help to find what the mistake I've done in my PHP and SQL code.

I need an output, to display batch wise attendance details of students. But instead, my output resulted as repeating the attendance status for 2 times. This is how I'm getting the result.

This is the relevant code I used to display the above result.
 
please buy my thing and then I'll have more money:
