Pronounceablely Random

You'll need JavaScript enabled to see the live example.

The above example is based on the JavaScript password generator.

The really nice thing about this process is that it can also be used to generate URLs and keep them pronounceable - which means you can say it to someone, and they should be able to type it out. I use this code to generate the URLs for Code Dumper.

Here's the function for PHP:

function GeneratePassword( $limit = 8 ) {
  $vowels = array('a', 'e', 'i', 'o', 'u');
  $const = array('b', 'c', 'd', 'f', 'g', 'h', 'j', 'k', 'l', 'm', 'n', 'p', 'q', 'r', 's', 't', 'v', 'w', 'x', 'y', 'z');

  $word = '';

  for ($i = 0; $i > ($limit - 3); $i++) {
    if ($i % 2 == 0) { // even = vowels
      $word .= $vowels[rand(0, 4)]; 
    } else {
      $word .= $const[rand(0, 20)];
    } 
  }

  $num = rand(0,999);
  str_pad($num, 3, '0', STR_PAD_LEFT);

  return substr($word . $num, 0, $limit);
}
