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).

Comments

  1. Permalink to comment#

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


    # like this

  2. Brad
    Permalink to comment#

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

  3. Permalink to comment#

    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();
    

    }

    */

  4. We can also use hashes (#) for comment

    Eg:

    <?php
    #Your comment
    ?>
    

Leave a Comment

Posting Code

Markdown is supported in the comment area, so you can write inline code in backticks like `this` or multiline blocks of code in in triple backtick fences like ```this```. You don't need to escape code in backticks, Markdown does that for you.

Sadly, it's kind of broken. WordPress only accepts a subset of HTML in comments, which makes sense, because certainly some HTML can't be allowed, like <script> tags. But this stripping happens before the comment is processed by Markdown (via Jetpack). It seems to me that would be reversed, because after Markdown processes code in backticks, it's escaped, thus safe. If you think you can fix this issue, get in touch!

If you need to make sure the code (typically HTML) you post absolutely posts correctly, escape it and put it within <pre><code> tags.
