This is a very simple but useful function to return number of digits of an integer. 

//function declaration
function count_digit($number) {
return strlen((string) $number);
}

//function call
$num = 12312;
$number_of_digits = count_digit($num); //this is call :)
echo $number_of_digits; 
//prints 5
