PHP algorithm questions to be in-depth (code added after implementation...)

Only print 0

　The specific number is determined by the input parameter n

If n=5, print For if

　for switch implementation

　while if implements

　while switch implements

make a calculator

　For example, test.php?a=1&b=2&operator=jia outputs 3

　For example, test.php?a=5&b=2&operator=jian outputs 3

　For example, test. php?a=2&b=5&operator=cheng outputs 10

　For example, test.php?a=6&b=3&operator=chu outputs 2
