在 PHP 中显示带序号后缀的数字
我想如下显示数字
- 1 为 1,
- 2 次,
- ...,
- 150 为 150.
我应该如何为代码中的每个数字找到正确的序数后缀(st、nd、rd 或 th)?
How should I find the correct ordinal suffix (st, nd, rd or th) for each number in my code?
推荐答案
来自维基百科:
$ends = array('th','st','nd','rd','th','th','th','th','th','th');
if (($number %100) >= 11 && ($number%100) <= 13)
$abbreviation = $number. 'th';
else
$abbreviation = $number. $ends[$number % 10];
其中 $number
是您要写入的数字.适用于任何自然数.
Where $number
is the number you want to write. Works with any natural number.
作为一个函数:
function ordinal($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);
