Comments are very good practice during your code it can reduce your maintenance efforts. Php supports mainly two type of comments.

1. Single Line Comment
2. Multi line comment

Single Line Comment
Single line comment used to comment the content from an single line only and the syntax for single line comments is as follows.

?>

Or
Multi Line Comment
Multi line comments used to comment multiple line simultaneously, If you needs to comment an block of code together then these multi line of code can be used such as follows.
