On "23-Dec-2008 07:20", Anonymous gave this function to calculate the number of digits:
function digit_count($num){
for($i=0;pow(10,$i)<=$num;$i++){
if(pow(10,$i+1)>$num){
$num_digits = $i+1;
}
}
return $num_digits;
}
However this is better:
function digit_count($num){
return strlen((string)$num);
}
