I was working on my site featuring posts for dynamic data which I can get from csv and show listing in Ordinal number format then I think it should be a define function to dynamically set ordinal number format. Here is function I have defined and posted here.

In function used first parameter for number only and second parameter is used to add sup html tag which can automatically move Ordinal format to top position both are examples defined in below.

This function is mostly used to show months dates with Ordinal format eg: today is 29th February 2016

function OrdinalNumberFormat($number,$add_sup=false){
	$format = 'th';
	$numlen = strlen($number);
	$lasttwonum = substr($number,$numlen-2,2);
	$lastone = substr($number,$numlen-1,1);
	if( ($lastone==1 || $number==1 ) && $lasttwonum!=11){
		$format = 'st';
	} else if($lastone==2 && $lasttwonum!=12){
		$format = 'nd';
	} else if($lastone==3 && $lasttwonum!=13){
		$format = 'rd';
		$format = '<sup>'.$format.'</sup>';
	return $number.$format;

Ordinal Number Format example without sup tag

for($OrdinalINC=1; $OrdinalINC<=50;$OrdinalINC++){
	echo OrdinalNumberFormat($OrdinalINC).' ';
