PHP Multiline Comments

Commenting and uncommenting selected text in PHP is very important for developers. A comment in PHP code is a section or line that is not executed as a part of the program. Its only making it easier for others (or yourself) to understand the code later.

In this TapGen PHP Tutorial, we will learn Single-line comments and Multiline Comments in PHP.

Multiline Comments syntax 

Comments will be created using the /* ... */ syntax. Anything between the opening /* and the closing */ will be treated as a comment and ignored by the PHP interpreter.

Example:

 
<?php
/*
This is a multiline comment.
Use it to explain your code or to temporarily disable code.
*/

echo "Hello, tapgen!";
?>
 
 

Output

Single Comments syntax 

A regular comment or a single-line comment can be created using either // or #.

Here is an example:

 
<?php
// This is a single-line comment
echo "Hello, World!"; // This will print a message
?>
 
 

A single-line comment is also used for adding quick notes next to a line of code.

Using #

 
 <?php
# This is another single-line comment
echo "Hello again Tapgen!"; # This too will print a message
?>
 
 

You can use multiline or single-line comments anywhere in your PHP code, including inside functions, classes, or anywhere else.

Uncomment the selection

To uncomment a selection of code in PHP, Simply remove the syntax.
 

Why use Single-line comments and Multiline Comments in PHP?

1. Documentation: They allow you to provide detailed explanations or descriptions of complex code sections, making it easier for others (or yourself) to understand the code later.

2. Temporarily Disable Code: You can quickly comment out large blocks of code during debugging or testing without needing to prepend each line with // or #.

3. Licenses and Copyright: Multiline comments are often used at the top of scripts to include licensing information, authorship, or other relevant metadata.

4. Code Collaboration: When working in teams, multiline comments can help clarify intent, making collaboration smoother and more efficient.

Using multiline comments effectively can enhance code quality and maintainability.
