Write one or two PHP statements that print "even" if an integer variable $num is even. $($Hint: Use the modulus operator$).$

Write one or more PHP statements that print "even" if an integer variable $num is even, and "odd" otherwise.$$ These must be new lines of code and not the same lines of code as in item $1.$

Write one or more PHP statements that print $"$A$"$ for a grade of $90-100,"$B$"$ for $80-89,"$C$"$ for $70-79,"$D$"$ for $60-69$ and $"$F$"$ otherwise.$$ If you don't like $101$ being an $"$F$",$ you can modify these for grades greater than $100.$ Name your variable $grade.

Write a switch statement and other necessary statements that take an integer variable $num and print the corresponding month, e$.$g$.$ "January" for $1,$ "February" for $2,...$

Test your code with different values for $num and $grade.$$ Use arrays or loops or arrays and loops to test.

Test item $1.$ with a variable or array using values $3$ and $6.$

Do not use $3$ or $6$ in any PHP conditional statement $($if$,$ else if$,$ else, $?$ :$).$

Test item $2.$ with a variable or array using values $3$ and $6.$

Do not use $3$ or $6$ in any PHP conditional statement $($if$,$ else if$,$ else, $?$ :$).$

Test item $3.$ with values $0,59,60,69,70,79,80,89,90,99,100,101$

Test item $4.$ with values $1,2,3,4,5,6,7,8,9,10,11,12,13$

Add PHP comments before each of these items to keep them separate.$$ The code for each is its own code.$$ Do NOT write code that tries to do $1$ and $2$ together.
