 # PHP: Arithmetic Operators

## Description

There are five basic arithmetic operators.

• - (subtraction)
• * (multiplication)
•  / (division)
• % (modulus)

The operators are summarized in the following table.

Operator Name Example Result
+ Addition \$x + \$y Sum of \$x and \$y.
- Subtraction \$x - \$y Difference of \$x and \$y.
* Multiplication \$x * \$y Product of \$x and \$y.
/ Division \$x / \$y Quotient of \$x and \$y
% Modulus \$x % \$y Remainder of \$x divided by \$y.

Example:

``````<?php
\$x=100;
\$y=60;
echo "The sum of x and y is : ". (\$x+\$y) ."<br />";
echo "The difference between x and y is : ". (\$x-\$y) ."<br />";
echo "Multiplication of x and y : ". (\$x*\$y) ."<br />";
echo "Division of x and y : ". (\$x/\$y) ."<br />";
echo "Modulus of x and y : " . (\$x%\$y) ."<br />";
?>
``````

Output:

```The sum of x and y is : 160
The difference between x and y is : 40
Multiplication of x and y : 6000
Division of x and y : 1.6666666666667
Modulus of x and y : 40```

Note : In the case of division, the operator returns a float value if the two operands are not integers.

## PHP: Tips of the Day

Output a Multidimensional Array with index and value and print into the table

Example:

```Array
(
 => Array
(
[id] => 13
[category_id] => 7
[name] => Leaving Of Liverpool
[description] => Leaving Of Liverpool
[price] => 1.00
[virtual] => 1
[active] => 1
[sort_order] => 13
[created] => 2007-06-24 14:08:03
[modified] => 2007-06-24 14:08:03
[image] => NONE
)
```
``` => Array
(
[id] => 16
[category_id] => 7
[name] => Yellow Submarine
[description] => Yellow Submarine
[price] => 1.00
[virtual] => 1
[active] => 1
[sort_order] => 16
[created] => 2007-06-24 14:10:02
[modified] => 2007-06-24 14:10:02
[image] => NONE
)
)
```
```<table>
<?php
foreach (\$products as \$key => \$value) {
foreach (\$value as \$k => \$v) {
echo "<tr>";
echo "<td>\$k</td>"; // Get index.
echo "<td>\$v</td>"; // Get value.
echo "</tr>";
}
}
?>
</table>
```
