Convert numbers to a pretty format using PHP or Angular 2 Typescript Pipe.

• 200 = 200
• 2,000 = 2K
• 2,100 = 2.1K
• 20,000 = 20K
• 20,100 = 20.1K
• etc

Greetings. After I uploaded my code to Github and googled for "pretty numbers php" I saw that we created something similar ( https://github.com/SirDagen/php-beautiful-numbers ). Nice to know. - btw I love your compact code

Is there a way to do reverse? If i enter numbers with k or m it should convert to full number?

It does not work for all numbers.

Try these edge cases,

human_number(100000); //Returns 1K
human_number(20000); //Returns 2K

Here is the simpler version,

// Constants
// 1E9 = 1000000000
// 1E6 = 1000000
// 1E3 = 1000

function human_number($number)
  {
    if ($number >= 1E9) {
        return round($number / 1E9, 2).'b';
    } else if ($number >= 1E6) {
        return round($number / 1E6, 2).'m';
    } else if ($number >= 1E3) {
        return round($number / 1E3, 2).'k';
    }
    return $number;
}
