PHP Comments

Comments are an essential part of coding as they help explain the code and make it more readable. In PHP, comments can be added using different syntaxes.

Key Topics

Types of Comments

PHP supports several types of comments:

  • Single-line comments: Start with // or #.
  • Multi-line comments: Enclosed between /* and */.

Example: Using Comments in PHP

<?php
// This is a single-line comment
# This is also a single-line comment

/* This is a multi-line comment
   that spans multiple lines */

echo "Hello World!"; // Outputting Hello World
?>

Output:

Hello World!

Explanation: Comments are ignored by the PHP engine and are used solely for documentation purposes. They help developers understand the code better. This example demonstrates single-line comments using // and #, as well as multi-line comments using /* ... */. The echo statement outputs Hello World!.

Important Note

Using comments effectively can significantly improve code maintainability and collaboration among developers.
