Comments in PHP

<?php

    /*
           This code by Chris Coyier
    */

    $i = 0;    // counter to be used later;

?>

Comments in PHP can be between /* */ markings (useful for multiple line comments) or after // markings (for single lines only).

    Have you tried the other type of comments? you use the # sign and they work like // comments.

    Can you help me with a small text based counter script ? It says something like permission error.

    I think its best to avoid using the multiline version for short blocks if you can.
    The reason is that they don’t nest well. So if you use, “/asterisk A comment asterisk/”
    in a
    function and latter comment out the function with “/asterisk asterisk/”. You wont get what you want.
    For example:

    /*
    function test()
    {
    /*This is a comment */

      invade_mars();
    

    }

    */

    We can also use hashes (#) for comment

    Eg:

    <?php
    #Your comment
    ?>

    I have a question, how about these lines
    <!-- Start --> , <!-- End -->
    can I use this kind on annotation in php files or this actually is considered a php command line? Thanks,

Posting Code

We highly encourage you to post problematic HTML/CSS/JavaScript over on CodePen and include the link in your post. It's much easier to see, understand, and help with when you do that.

Markdown is supported, so you can write inline code like `<div>this</div>` or multiline blocks of code in in triple backtick fences like this:

```
<script>
  function example() {
    element.innerHTML = "<div>code</div>";
  }
</script>
```
