Understanding Operators in PHP
PHP (Hypertext Preprocessor) is a popular scripting language used for web development, and operators in PHP are essential for performing various operations. Operators allow you to manipulate data, perform mathematical calculations, and compare values. PHP provides a rich set of operators that can be used to write efficient and dynamic code.
In this article, we will dive deep into the different types of operators available in PHP, explain their uses, and provide examples to help you understand them better.
1. Arithmetic Operators
Arithmetic operators are used to perform basic mathematical operations such as addition, subtraction, multiplication, division, and more.
Common Arithmetic Operators in PHP
| Operator | Description | Example |
|---|---|---|
| + | Addition | $a + $b |
| - | Subtraction | $a - $b |
| * | Multiplication | $a * $b |
| / | Division | $a / $b |
| % | Modulus (Remainder) | $a % $b |
| ** | Exponentiation | $a ** $b |
Example
$a = 10;
$b = 3;
echo $a + $b; // Output: 13
echo $a - $b; // Output: 7
echo $a * $b; // Output: 30
echo $a / $b; // Output: 3.3333333333333
echo $a % $b; // Output: 1
echo $a ** $b; // Output: 1000
