Comments in PHP
A comment in PHP code is a line that is not executed as a part of the
program. Its only purpose is to be read by someone who is looking at the code.
Comments can be used to:
Let others understand your code
Remind yourself of 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 several ways of commenting:
Example
Syntax for single-line comments:
<!DOCTYPE html>
<html>
<body>
<?php
// This is a single-line comment
# This is also a single-line comment?>
</body>
</html>
Example
Syntax for multiple-line comments:
<!DOCTYPE html>
<html>
<body>
<?php
/*
This is a multiple-lines comment blockthat spans over multiplelines
*/?>
</body>
</html>
Example
Using comments to leave out parts of the code:
<!DOCTYPE html>
<html>
<body>
<?php
// You can also use comments to leave out parts of a code line$x = 5 /* + 15 */ + 5;echo $x;?>
</body>
</html>
