Comments in PHP
In PHP, you can use comments to add notes and explanations to your code. Comments are ignored by the PHP interpreter and are not executed as part of your program.
There are two types of comments in PHP: single-line comments and multi-line comments.
Single-line comments are denoted by a # symbol or by //. Anything following these symbols on the same line is considered a comment.
Here’s an example of a single-line comment:
<?php
# This is a single-line comment
echo "Hello, world!";
?>Multi-line comments are denoted by /* and */. Anything between these symbols is considered a comment, and can span multiple lines.
Here’s an example of a multi-line comment:
<?php
/*
This is a multi-line
comment
*/
echo "Hello, world!";
?>
Comments are a useful way to document your code and make it easier to understand. They can also be used to temporarily disable certain lines of code while you are debugging or testing your program.
