Source code embedding in blog. One simple way found here Following is one sample code snippet

   1:   <?php

   2:  

   3:        /* Initialize some variables using C style comments

   4:  

   5:              $a - contains a-coefficient

   6:  

   7:              $b - contains b-coefficient

   8:  

   9:              $x - value we are evaluating

  10:  

  11:              $y - result from evaluating equation */

  12:  

  13:        $a = 1; $b = 2; $x = 1;

  14:  

  15:        $y = $a * $x + $b;

  16:  

  17:        if ( $y < 5 )                // C++ style comment, check if y<5

  18:  

  19:        {

  20:  

  21:                # Shell style comment, display something when y<5

  22:  

  23:                echo "Guess what?  y is less than 5!";

  24:  

  25:        }
