Display Numbers With Ordinal Suffix in PHP

Display numbers with ordinal suffix in PHP

from wikipedia:

$ends = array('th','st','nd','rd','th','th','th','th','th','th');
if (($number %100) >= 11 && ($number%100) <= 13)
   $abbreviation = $number. 'th';
else
   $abbreviation = $number. $ends[$number % 10];

Where $number is the number you want to write. Works with any natural number.

As a function:

function ordinal($number) {
    $ends = array('th','st','nd','rd','th','th','th','th','th','th');
    if ((($number % 100) >= 11) && (($number%100) <= 13))
        return $number. 'th';
    else
        return $number. $ends[$number % 10];
}
//Example Usage
echo ordinal(100);

Display date with ordinal suffix in PHP

You can specify any character that you want:

$newDate = date("l M d\t\h Y", strtotime($date));

But if you want to get 1st, 2nd, 3rd, 4th ... you should use:

$newDate = date("l M jS Y", strtotime($date));

Display number as Ordinal number in 'word form' with NumberFormatter PHP class?

You want to be using the SPELLOUT format style, rather thanORDINAL.

The next problem is how to tell the formatter to use the particular ruleset that you are interested in; namely %spellout-ordinal. This can be done by using setTextAttribute().

Example

$formatter = new NumberFormatter('en_US', NumberFormatter::SPELLOUT);
$formatter->setTextAttribute(NumberFormatter::DEFAULT_RULESET,
                             "%spellout-ordinal");

for ($i = 1; $i <= 5; $i++) {
    echo $formatter->format($i) . PHP_EOL;
}

Output

first
second
third
fourth
fifth

add 'rd or 'th or 'st dependent on number

I don't know of any built-ins that do this, but this should work:

function ordinal_suffix($num){
    $num = $num % 100; // protect against large numbers
    if($num < 11 || $num > 13){
         switch($num % 10){
            case 1: return 'st';
            case 2: return 'nd';
            case 3: return 'rd';
        }
    }
    return 'th';
}

(note 11, 12 and 13 are special cases - 11th, 12th, 13th vs 11st...)

Formatting date, ordinal suffix for the day of the month

Look at the formats here http://www.php.net/manual/en/function.date.php, but

<?php echo date_format($date, "jS M Y") ?><br>

For international dates, I guess you would do something like:

$ordinal = new NumberFormatter($locale, NumberFormatter::ORDINAL);
$ordinal = $ordinal->format(date_format($date, "j"));
$pattern = "d'{$ordinal}' MMM yyyy";
$dateFormatter = new IntlDateFormatter($locale, IntlDateFormatter::FULL, IntlDateFormatter::FULL, $timezone, IntlDateFormatter::GREGORIAN);
$dateFormatter->setPattern($pattern);
$dateFormatter->format($date->getTimestamp());

The above is untested but it seems like it would work.

Add st, nd, rd and th (ordinal) suffix to a number

The rules are as follows:

st is used with numbers ending in 1 (e.g. 1st, pronounced first)

nd is used with numbers ending in 2 (e.g. 92nd, pronounced ninety-second)

rd is used with numbers ending in 3 (e.g. 33rd, pronounced thirty-third)

As an exception to the above rules, all the "teen" numbers ending with 11, 12 or 13 use -th (e.g. 11th, pronounced eleventh, 112th,
pronounced one hundred [and] twelfth)

th is used for all other numbers (e.g. 9th, pronounced ninth).

The following JavaScript code (rewritten in Jun '14) accomplishes this:

function ordinal_suffix_of(i) {
    var j = i % 10,
        k = i % 100;
    if (j == 1 && k != 11) {
        return i + "st";
    }
    if (j == 2 && k != 12) {
        return i + "nd";
    }
    if (j == 3 && k != 13) {
        return i + "rd";
    }
    return i + "th";
}

Sample output for numbers between 0-115:
