How to Add Ordinal Number Suffix Using PHP

Ordinal number indicates a position in relation to other numbers e.g first, second, third and so on. An ordinal number carries a suffix nd, rd, st or th.

Here, I am going to explain how to add ordinal number suffix with using simple PHP function. This function will take a number as an input parameter and return number with a suffix like first, second, third and forth, etc.

Add Ordinal Number Suffix PHP Function

<?php

 function addOrdinalNumberSuffix($num) {
 if (!in_array(($num % 100),array(11,12,13))){
 switch ($num % 10) {
 // Handle 1st, 2nd, 3rd
 case 1:  return $num.'st';
 case 2:  return $num.'nd';
 case 3:  return $num.'rd';
 }
 }
 return $num.'th';
 }

 for ($i = 1; $i <= 100; $i++){
 echo addOrdinalNumberSuffix($i) . "\t";
 if ($i % 10 == 0) {
 echo "\n";
 }
 }
?>

Output :-

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