Write a PHP Class with these methods:

primesInRange$($$a$,$ $b$)$;

Given two numerical parameters in input, computes and prints all the prime numbers in between the

two numerical values.

Example:

If input parameters are $3$ and $10,$ output is $"3,5,7"$

If input parameters are $1$ and $100,$ output is $"2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,$

$53,59,61,67,71,73,79,83,89,97"$

A tester method for "primeslnRange"

Given a specific subset of inputs, tests the method described above.

Example, in pseudo code:

tester$\_$function:

is output from prime$\_$function$(5,10)$ equal to $"5,7"?$ If yes, test passed

is output from prime$\_$function $(1,4)$ equal to $22,3?$ If yes, test passed

$..$

Implement all the necessary helper methods and attributes $($class variables$)$ for your class.
