## PHP Operators
|
|
|
|
<p>Operators are used to perform operations on variables and values.</p>
|
|
<p>PHP divides the operators in the following groups:</p>
|
|
<ul>
|
|
<li>Arithmetic operators</li>
|
|
<li>Assignment operators</li>
|
|
<li>Comparison operators</li>
|
|
<li>Increment/Decrement operators</li>
|
|
<li>Logical operators</li>
|
|
<li>String operators</li>
|
|
<li>Array operators</li>
|
|
</ul>
|
|
<h3>PHP Arithmetic Operators</h3>
|
|
<p>The PHP arithmetic operators are used with numeric values to perform common arithmetical operations, such as addition, subtraction, multiplication etc.</p>

### PHP Assignment Operators
|
|
|
|
The assignment operator is `=`. The operand on the left side gets assigned the value of the expression on the right.
|
|
|
|
#### Example
|
|
|
|
```php
|
|
<?php
|
|
|
|
$a = 7; // $a set to 7.
|
|
|
|
?>
|
|
```
