In “if_else statement” we can also evaluate one variables with many strings? For example we suppose

variable $number=10 in if_else statement as we did in “if statement”, its output will be equal to 10.

If value is 11 or any other value in “else_if statement”,it will echo out 11 if it is actually equal

to 11.Again in “else statement” if value is not equal to 10 niether 11 then it will echo out “Not

equal”. In this way you can evaluate many variables at a time with help of “if_else if_else

statement”.
