[SOLVED] Numbering

[Kingy]

With my rank i am outputting something like

 

You are ranked XXst/nd/rd/th

 

eg:

1st, 2nd, 3rd, 4th

           if(($rank == 1) || ($rank == 21) || ($rank == 31)) {
             $suffix = "st";
           } elseif (($rank == 2) || ($rank == 22) || ($rank == 32)) {
             $suffix = "nd";
           } elseif (($rank == 3) || ($rank == 23) || ($rank == 33)) {
             $suffix = "rd";
           } else {
             $suffix = "th";
           }

i have that and it works, but is there simpler way of doing it so as my numbers grow i don't have to keep adding if $rank == 41,51,61 etc etc

You have to test only the last digit of each number, anything else (and any of the "teens") will end in "th".

yeah i understand that, so what sort of code would i use to do that

[Ken2k7]

function last_digit(num){
return (num > 10)? last_digit(num%10) : num;
}

 

I think that would work

try

<?php
function my_suffix($b){
if ($a<0) $a = -$b; else $a =$b;
$s = array('th', 'st', 'nd');
$su = $a % 10;
if (((int)($a / 10)) % 10 == 1) $su = 0;
if ($su > 2) $su = 0;
return $s[$su];
}

echo my_suffix(191);
?>

Ugh, I forgot the $ in variables. :S Well you get the idea.

 

@sasa, what's $a?

[Kingy]

woah that looks interesting, and works too, but doesn't contain 'rd' for 3rd

 

how do u fit rd in there :s

[kenrbnsn]

I did a search in Google and came up with this Ordinal number printer function

 

<?php
function ordinal($number) {

    // when fed a number, adds the English ordinal suffix. Works for any
    // number, even negatives

    if ($number % 100 > 10 && $number %100 < 14)
        $suffix = "th";
    else {
        switch($number % 10) {

            case 0:
                $suffix = "th";
                break;

            case 1:
                $suffix = "st";
                break;

            case 2:
                $suffix = "nd";
                break;

            case 3:
                $suffix = "rd";
                break;

            default:
                $suffix = "th";
                break;
        }

    }

    return "${number}<SUP>$suffix</SUP>";

}
?>

ups

try

<?php
function my_suffix($b){
if ($a<0) $a = -$b; else $a =$b;
$s = array('th', 'st', 'nd', 'rd');
$su = $a % 10;
if (((int)($a / 10)) % 10 == 1) $su = 0;
if ($su > 3) $su = 0;
return $s[$su];
}

echo my_suffix(191);
?>
