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 -> 142,840 

BUT

2023150 -> 2.023M ( i still want 3 additional numbers for more accuracy ) 5430120215 -> 5.430B 

I would totally appreciate any custom functions to dynamically choose the limit if possible.

Answer 1

Use number_format():

if ($n < 1000000) {     // Anything less than a million     $n_format = number_format($n); } else if ($n < 1000000000) {     // Anything less than a billion     $n_format = number_format($n / 1000000, 3) . 'M'; } else {     // At least a billion     $n_format = number_format($n / 1000000000, 3) . 'B'; } 

I would totally appreciate any custom functions to dynamically choose the limit if possible.

If "limit" refers to the number of decimal places (the precision), that's easy:

function custom_number_format($n, $precision = 3) {     if ($n < 1000000) {         // Anything less than a million         $n_format = number_format($n);     } else if ($n < 1000000000) {         // Anything less than a billion         $n_format = number_format($n / 1000000, $precision) . 'M';     } else {         // At least a billion         $n_format = number_format($n / 1000000000, $precision) . 'B';     }      return $n_format; }
