    About Lesson

    A comment is non-executable lines. It is used to write a description for a better understanding. The web browser doesn’t read the comments.

    • Single line comments
    • Multi-lines comments

     

    Single line comments:

    There are two ways to use single-line comments in PHP.

    // (C++ style single line comment)

    # (Unix Shell-style single line comment)

    <?php
    echo "Welcome to PHP language";
    // (C++ style single line comment)
    # (Unix Shell-style single line comment)
    ?>

     

    Multi-line comments

    Multi-line comments are used to comment on multiple lines. For multi-line comments, we need to enclose all lines within /* … */.

    <?php 
    /* 
    This is a comment with a multi-line comment 
    Developer: infovistar.com 
    */
    echo “Welcome to PHP language”; 
    ?>
