Converting number abbreviations (5.2k, 1.7m, etc) into valid integers with PHP

Question

I have a database with a column containing a variety of numbers written in \"shorthand\", for example:

5k for 5,000
86.6k for 86,600
4.1m for 4,100,000
1

Answer 1

$string = '5k'; // or whatever
$suffix = strspn($string, '.0123456789');
$value = doubleval(substr($string, 0, $suffix))
if($suffix < strlen($string))
{
 switch($string[$suffix])
 {
  case 'k':
   $value *= 1000;
   break;
  case 'm':
   $value *= 1000000;
   break;
  case 'b':
   $value *= 1000000000;
   break;
 }
}
echo number_format($value);
