Php function to add st, nd, rd, th to the end of numbers

Often numbers are to be written with a proper suffix, like 1st, 2nd, 3rd, 15th, 21st and so on.

So here is a quick function to do the same for a number.

Technique 1

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

/* This function will add st, nd, rd, th to the end of numbers */   function ordinal($i) {     $l = substr($i,-1);     $s = substr($i,-2,-1);           return (($l==1&&$s==1)||($l==2&&$s==1)||($l==3&&$s==1)||$l>3||$l==0?'th':($l==3?'rd':($l==2?'nd':'st'))); }   /*     Example usage */   for($i = 0; $i < 100; $i++) {     echo $i . ordinal($i). '<br />'; }

Technique 2

Php 5.3+ has the NumberFormatter class from the intl pecl package, which can be used to do the same thing in a much better way by taking into account localisation.

To install intl on ubuntu type the following at the terminal

$ sudo apt-get install php5-intl

Example

1 2	$nf = new NumberFormatter('en_US', NumberFormatter::ORDINAL); print $nf->format(123); // prints 123rd
