Problem with vezquex at gmail dot com's function is it will produce 211th 212nd & 213rd when it should follow the same pattern of x11th, x12th and x13th.

<?
function number_suffix2($n)
{
	$s = array( 'st' , 'nd' , 'rd' );
	$e = (int) substr( $n , -2 );
	$x = $n % 10 - 1;
	
    return $n.( (array_key_exists( $x , $s ) && ( $e < 10 || $e > 13 ) ) ? $s[$x] : 'th' );
}
?>
