function randompass(){
	srand();
	$password = (int)rand(0,100);
	$password = strtr($password, '0123456789', 'ymifxupbck');
	$x = (int)rand(0,77);
	$x = strtr($x,'0123456789','q8ft9s6jm3');
	$password .= $x;
	$x = (int)rand(0,89);
	$x = strtr($x,'0123456789','y6uognkdxw');
	$password .= $x;
	$x = (int)rand(0,188);
	$x = strtr($x,'0123456789','pouytreewq');
	$password .= $x;
	$x = (int)rand(0,65);
	$x = strtr($x,'0123456789','lkklhtfaut');
	$password .= $x;
	return $password;
}

// The following will assign a string of length 32 characters,
// so make sure your size of your database column can accomodate
// all 32 characters. (e.g. CHAR (32) )
$random = md5(uniqid(rand(), true));

Why not use something a bit simpler?

function generate_password()
{ 
  $salt = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"; 
  srand((double)microtime()*1000000);
  $pass = "";
  for($count = 0; $count < 8; $count++)
  {
    $num = rand() % 33;
    $tmp = substr($salt, $num, 1);
    $pass = $pass.$tmp;
  }
  return $pass;
}

then just do this:

$randpass = generate_password();
