How to do single and multi line comment in PHP?

by

PHP single line comment is made in two ways:

  • Using // (C++ style single line comment)
  • Using # (Unix Shell style single line comment)
    PHP multi-line comment is made by enclosing all lines within.

In PHP, you can use single-line comments using // and multi-line comments using /* */. Here’s how you do it:

Single-line comment:

php
// This is a single-line comment

Multi-line comment:

php
/*
This is a multi-line comment
It can span multiple lines
*/

These comments are used to document your code, add explanations, or temporarily disable certain parts of your code during development. They are ignored by the PHP interpreter when executing the script.
