Shorten long numbers to K/M/B?

Question

I\'ve googled this a lot but i can\'t find any helpful functions based on my queries.

What i want is:

100 -> 100
1000 -> 1,000
142840 -> 142         


        

Answer 1

function number_abbr($number)
{
    $abbrevs = [12 => 'T', 9 => 'B', 6 => 'M', 3 => 'K', 0 => ''];

    foreach ($abbrevs as $exponent => $abbrev) {
        if (abs($number) >= pow(10, $exponent)) {
            $display = $number / pow(10, $exponent);
            $decimals = ($exponent >= 3 && round($display) < 100) ? 1 : 0;
            $number = number_format($display, $decimals).$abbrev;
            break;
        }
    }

    return $number;
}

Works for positives and negatives.
