PHP comments

• A comment in PHP code is a line that is not read/executed as part of the program. Its

only purpose is to be read by someone who is editing the code!

• Comments are useful for:

o To let others understand what you are doing - Comments let other

programmers understand what you were doing in each step (if you work in a

group)

o To remind yourself what you did - Most programmers have experienced

coming back to their own work a year or two later and having to re-figure out

what they did. Comments can remind you of what you were thinking when you

wrote the code

• PHP supports three ways of commenting:

Single comments:-

//Single comments

# single comments

Multiline comment:-

Example:-

<!DOCTYPE html>

<html>

<body>

<?php

// This is a single line comment

# This is also a single line comment

This is a multiple lines comment block

that spans over more than

one line

</body>

</html>
