PHP Comments and its use inside code

Comments are used in php to not to execute a part or a line of code. Use of comments is a good practice and it helps in code maintenance for future modification and updating. By using comments we can comment or stop executing on a part of a line or in a block of code. You can read the HTML comments also. Here basic difference between html comment and php comment is in case of php comments; server never sends them to browser, where as all html comments are posted to browser but browser stops displaying them. Any one can see html comments by checking the view – source of the page. The comments are inserted in any part of the PHP code.

To comment we can use //
Or we can use #
Or we can use /*


Here is some example of use of comments in PHP code.

echo “Hello world”; // this part is commented and not displayed

//echo “This will not be displayed as commented “;

#echo “this is also commented “;


To comment more than one line or a block of code we can write like this


/* echo “ This is commented “;
echo “This is also commented “;
echo “this is also commented, so not displayed”;
*/


echo “this is displayed “;

In this type of code we must write a stop comment also like */ along with start comment like /*
