JavaScript-How to display the number of readings in PHP or JS friendly? For example, convert 1000 to 1k,10000 to 1w

More than 1000 of the number can be formatted as 1k
e.g. 1320 conversion to 1.3k
or 13200 conversion to 1.32w

effect, in the Internet for a long time, have not found this plug-in, which God can tell me where to find, or the name of such plug-in is what, thank you ~

function test($num){    if($num < 1000) {       return $num;    } else if($num >=1000 && $num < 10000){       return round($num/1000,1).'k';    } else if ($num >= 10000) {       return round($num/10000,2).'w';    }}echo test(1320);

  
   = 10000) {        $num = round($num / 10000 * 100) / 100 .' W';    } elseif($num >= 1000) {        $num = round($num / 1000 * 100) / 100 . ' K';    } else {        $num = $num;    }    return $num;}echo num2tring(12300); //1.23 Wecho num2tring(1200); //1.2 Kecho num2tring(200); //200

In JavaScript, the number is divided by 1000, then the result is rounded down with Math.floor, and the end is prefixed with K.
Math.floor (n/1000) + ' k ' K
PHP also has a similar usage
