Remarks#

Keep the following tips in mind when deciding how to comment your code:

You should always write your code as if comments didn’t exist, using well chosen variable and function names.
Comments are meant to communicate to other human beings, not to repeat what is written in the code.
Various php commenting style guides exist (e.g. pear, zend, etc). Find out which one your company uses and use it consistently!

The single line comment begins with ”//” or ”#“. When encountered, all text to the right will be ignored by the PHP interpreter.

// This is a comment

# This is also a comment

echo "Hello World!"; // This is also a comment, beginning where we see "//"

The multi-line comment can be used to comment out large blocks of code. It begins with /* and ends with */.

/* This is a multi-line comment.
   It spans multiple lines.
   This is still part of the comment.
