|
$a
+ $b |
Addition |
Addition
Sum of $a and $b. |
|
$a - $b |
Subtraction |
Difference
of $a and $b. |
|
$a * $b |
Multiplication |
Product
of $a and $b. |
|
$a / $b |
Division |
Quotient
of $a and $b. |
|
$a % $b |
Modulo |
Remainder
of $a divided by $b. |
|
$a ** $b |
Exponentiation |
Result
of raising $a to the $b'th power. |
Note: The division operator returns a float value unless the two
operands are integers (or strings that get converted to integers) and the
numbers are evenly divisible, in which case an integer value will be returned.
Example
<?PHP
$a = 22;
$b = 10;
$sum = $a + $b;
echo "Addition Operation Result: $sum <br/>";
$sum = $a - $b;
echo "Subtraction Operation Result: $sum <br/>";
$sum = $a * $b;
echo "Multiplication Operation Result: $sum <br/>";
$sum = $a / $b;
echo "Division Operation Result: $sum <br/>";
$sum = $a % $b;
echo "Modulus Operation Result: $sum <br/>";
?>
Result of the above example:
