Note Submitter: sedativchunk at gmail dot com ---- Not sure if this has been posted or not, but I found the switch statement useful for finding ranges of data. This script creates web 2.0 style links in different font sizes (popular on blogs) using a randomizer and switch statement. I used links from within a database for a mod I made for a Simple Machines forums, but this example uses arrays for links if you wanted to add your own custom links: <?php // Create set of links $link = array(); $link[] = '<a href="whatever.html">page 1</a>'; $link[] = '<a href="whatever.html">page 2</a>'; $link[] = '<a href="whatever.html">page 3</a>'; $link[] = '<a href="whatever.html">page 4</a>'; $link[] = '<a href="whatever.html">page 5</a>'; $link[] = '<a href="whatever.html">page 6</a>'; $link[] = '<a href="whatever.html">page 7</a>'; $link[] = '<a href="whatever.html">page 8</a>'; // Create loop to display links for($i = 0; $i < count($link); ++$i) { // Create randomizer // Use switch statement to find font size $randomizer = rand(1,50); switch($randomizer) { case ($randomizer <= 20): $font_size = "11"; break; case ($randomizer <= 30): $font_size = "16"; break; case ($randomizer <= 40): $font_size = "18"; break; case ($randomizer <= 50): $font_size = "20"; break; } // Display the link echo '<span style="font-size: ' .$font_size. ';">' .$link[$i]. '</span>&nbsp;&nbsp;'; // Loop the next link } ?> Using this type of range randomizer is useful for game development and it can be useful on the web too, for things where you don't want to use a randomizer just for things like (1-5) where you wanted a more then likely result for one thing over another. The switch statement saves from writing spaghetti code if statements.
