Comments

Comments in PHP are lines in the code that are not executed by the server. They are only written to help developers understand the code easily.

PHP comments are ignored when the program runs, so they do not affect the output of the program.

Comments are used to:

• Help others understand the code
• Remind yourself what the code does
• Temporarily hide parts of code for testing purposes

In PHP, comments are used to explain code and are ignored by the server when the program runs. There are two main types of comments in PHP.

Single-Line Comment

A single-line comment is used for short notes. It is written in one line.

Multi-Line Comment

A multi-line comment is used for long explanations. It can cover more than one line.
