Comments in PHP

In PHP, comments are used to add explanatory notes within the code, which are ignored by the PHP interpreter during execution. Comments help improve code readability and maintainability by providing context and explanations for different parts of the code. PHP supports two types of comments:

1. Single-Line Comments: Single-line comments start with two forward slashes (//). Everything after the // on the same line is considered a comment and is ignored by the PHP interpreter.
Copy

// This is a single-line comment
    echo "Hello, World!";

2. Multi-Line Comments: Multi-line comments begin with /* and end with */. Everything between /* and */, including line breaks, is treated as a comment.
Copy

/*
    This is a multi-line comment.
    It can span multiple lines.
    */
    echo "Hello, World!";

Comments can be used to describe the purpose of variables, functions, classes, or any other part of the code. They can also be used for temporarily disabling specific code lines for debugging or testing purposes.

It's good practice to include comments in your code to make it easier for other developers (or even yourself in the future) to understand the code's logic and functionality. However, it's essential to maintain a balance and avoid over-commenting, as excessive comments can clutter the code and reduce readability.
