I need to show a page views value in the format of 1K of equal to one thousand, or 1.1K, 1.2K, 1.9K etc, if its not an even thousands, otherwise if under a thousand, display normal 500, 100, 250 etc, using PHP to format the number?

I'm using:--

function count_number($n) {
    // first strip any formatting;
    $n = (0+str_replace(",","",$n));

    // is this a number?
    if(!is_numeric($n)) return false;

    // now filter it;
    if($n>1000000000000) return round(($n/1000000000000),1).'T';
    else if($n>1000000000) return round(($n/1000000000),1).'G';
    else if($n>1000000) return round(($n/1000000),1).'M';
    else if($n>1000) return round(($n/1000),1).'K';

    return number_format($n);
}

BUT it does not work correctly...

If my page visted 2454 times, it shows 2.5k and if 2990, it shows 3k...

How o fix that problem??

I want to SHOW Like --> if page visited 2454 -> how to display 2.4k and if 2990 -> 2.9k, if 3000 -> 3k etc

Plz help me...

Thanks @ MonkeyZeus

You can use this to calculate thousands. You can use this formula to figure out the formula for millions as well.

$n = 2000;
$formatted = '';

if($n >= 1000 && $n < 1000000)
{
    if($n%1000 === 0)
    {
        $formatted = ($n/1000);
    }
    else
    {
        $formatted = substr($n, 0, -3).'.'.substr($n, -3, -2);

        if(substr($formatted, -1, 1) === '0')
        {
            $formatted = substr($formatted, 0, -2);
        }
    }

    $formatted.= 'k';
}

echo $formatted;

Also, please use curly braces, ALWAYS. Future you will thank present you.
