<?php
class Common {

public static function generatePassword($length = 8)
{
	  // start with a blank password
	  $password = "";
	  // define possible characters
	  $possible = "0123456789abcdefghjkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ";  
	  // set up a counter
	  $i = 0; 
	    
	  // add random characters to $password until $length is reached
	  while ($i < $length) 
	  { 
	    // pick a random character from the possible ones
	    $char = substr($possible, mt_rand(0, strlen($possible)-1), 1);   
	    // we don't want this character if it's already in the password
	    if (!strstr($password, $char)) 
		{ 
	      $password .= $char;
	      $i++;
	    }

	  // done!
