Lesson 4- use of And-Or in If-Else

Use of “And” and “OR” in if –Else

When we need to check more than one condition in if-else, then we use “And” and “OR” operator in if else.

Use of “And”

When we need that all condition must be true then we use “And” operator.

For Example

Let’s take the previous example where we calculate gross salary. I am taking the same example here but with some changes. If candidate salary is greater than 10000 and his dept is hr then his pf will be 5% but for other dept the pf will be 2% with all salary.

Solution of this program will be as follows:-

<?php

$sal=6000;

$dept="hr";

$hra;

$gross_sal=0;

if($sal>10000 and $dept="hr")

{

$hra=($sal*5)/100;

$gross_sal=$sal+$hra;

}

else

{

$hra=($sal*2)/100;

$gross_sal=$sal+$hra;

}

echo " The Gross Salary is $gross_sal";

?>
