PHP comments are used to understand the functionality of the PHP code. One can easily distinguish the lines of code through comments. PHP language supports both single and multi-line comments. We can also hide the code through comments.
Following are the examples illustrating both single line and multi-line comments.
<?php // echo "What are you looking for?"; echo "Try this."; ?>
<?php # echo "Or this"; echo "Hey! I'm here."; ?>
Above example is to comment only a single line. You can also use '//' and '#' to comment a single line.
To comment more lines, use this /* ....... */:
<?php /* echo "My name"; $name="Vihaan"; This is used to comment the paragraph or lines more than one. */ echo "Got it ?"; ?>
