PHP comments are used to describe a specific section of code so that other developers can understand the code. Comments in PHP can also be used to hide any code. We can hide any code using comments in realtime to stop the execution of a specific part.
PHP supports a single line and multi-line comments. PHP comments are similar to any other programming language like C/C++, Java, and Perl style (Unix shell-style) comments.
Why comments are used
- Others developers can easily understand your code
- We can write comments as a reminder for us. we can later check the code in an easy way.
Single line comments are used to write a comment in a single line.
We can write single-line comments in two ways
- // This is a single-line comment
- # This is also single line comment
<?php // This is single-line comment # This is also single line comment echo "Welcome to single line comments"; ?>
Multi-Line Comments in PHP
In PHP, we can comments on multiple lines also. We can use /* */ to comment multiple lines.
<?php /* 1st line 2nd line 3rd line 4th line */ echo "Welcome to multi line comment section"; ?>
