### Introduction

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
}
``````

### Example of If-else

Now implement this example

``````

<?php
\$sal=12000;
\$hra;
\$gross_sal;
if(\$sal>10000)
{
\$hra=(\$sal*5)/100;
\$gross_sal=\$sal+\$hra;
}
else
{
\$hra=(\$sal*10)/100;
\$gross_sal=\$sal+\$hra;
}
echo " The Gross Salary is \$gross_sal";
?>

``````

In this example we take salary is 12000. Which is greater than 10000. Then it will go in if block and calculate the hra 5%.

The output of this code as follows:-

``````

Now move to the else-if condition.

Now take the same example in another way. If salary is greater than 10000 then hra will be 5% and if less than hra will be 10%. But if salary is 10000 then hra will be 8%.

Now implement this example:-

``````

<?php
\$sal=10000;
\$hra;
\$gross_sal;
if(\$sal==10000)
{
\$hra=(\$sal*8)/100;
\$gross_sal=\$sal+\$hra;
}
else if(\$sal>10000)
{
\$hra=(\$sal*5)/100;
\$gross_sal=\$sal+\$hra;
}
else
{
\$hra=(\$sal*5)/100;
\$gross_sal=\$sal+\$hra;
}
echo " The Gross Salary is \$gross_sal";
?>

```	```

The output of this code as follows:-
