I changed the fucntion created by chislam4444 at gmail dot com so that it is dynamic and the code is
shorter.
<?
function add_commas($num){
$decimalpos = strpos($num, ".");
if(!$decimalpos === false){
$startpos = $decimalpos;
} else {
$startpos = strlen($num);
}
$comma_string = $num;
$startpos -= 3;
for($a = $startpos; $a > 0; $a -= 3){
$comma_string = substr($comma_string, 0, $a) . "," . substr($comma_string, $a);
}
return $comma_string;
}
echo add_commas(30000); // 30,000
echo "<br>";
echo add_commas(300000); // 300,000
echo "<br>";
echo add_commas(3000000); // 3,000,000
?>
