PHP Comments

In PHP, comments are used to add explanatory notes within the code that are ignored by the PHP interpreter. Comments are helpful for developers to document their code, making it more readable and understandable. There are two types of comments in PHP: single-line comments and multi-line comments.

Single-line comments:

Single-line comments start with two forward slashes (//). Everything following the // on that line is considered a comment.

// This is a single-line comment $variable = 42; // You can also add a comment at the end of a line of code

Multi-line comments:

Multi-line comments are enclosed between /* and */. This type of comment can span multiple lines.

/* This is a multi-line comment spanning multiple lines */ $anotherVariable = "Hello, World!";

Comments are essential for code documentation, and using them appropriately can make your code more maintainable and understandable for yourself and other developers who may work on the code in the future.
