Lesson 3- if-else statement in PHP

Use of If-else Statement

In the earlier example we calculated the hra and gross salary.

Suppose there is a policy of company that if salary is greater than 10000 then hra will be 5% of salary but if salary is less than 10000 then hra will be 10%

In this situation we will use if-else statement.

Syntax of if-else:-

If (condition)

{

          Logic when condition true

}

Else

{

          Logic when condition false

}
