Comments in php

Comments are used for documenting the code for developer’s reference. The lines within the comments are not executed. PHP comments are similar to the C programming language.
There are two types of comments in PHP:

• ‘//’ is used to comment out a single line
• A block of lines should be contained within ‘/*’ and ‘*/’ to comment them.
