In this guide, you’ll learn about PHP operators, tools for performing calculations and comparisons in your PHP code.
Understanding Operators in PHP
Types of Operators
Operators are symbols that tell PHP to perform certain actions. Common operators include arithmetic, comparison, and logical operators.
Examples:
// Arithmetic operators
$sum = 5 + 3; // Addition
$diff = 10 - 4; // Subtraction
// Comparison operators
$is_equal = (5 == 5); // Equals
$is_greater = (10 > 5); // Greater than
// Logical operators
$is_true = true && false; // Logical AND
$is_either = true || false; // Logical OR
These operators let you perform calculations and make comparisons, a core part of programming in PHP.
