Solution 1

1. $Free scoped to the loop, so when you exit the loop the variable is gone...
2. SQL has built in aggregate functions including SUM - use them...

but how to declare a variable inside another variable like in C#,

int x=1;
string student;

while(x<=6)
{
print student(x);
x++;
}

Output will be
student 1
student 2 till 6

but in php i cant put

$student[$x] , or how to do this?

That's the exact difference x defined OUTSIDE the loop sot it does not wear out when the scope is gone...
Add '$Fee = [];' before your loop and it should work...
