PHP: get number of decimal digits

Question

Is there a straightforward way of determining the number of decimal places in a(n) integer/double value in PHP? (that is, without using explode)

Answer 1

If you want readability for the benefit of other devs, locale safe, use:

function countDecimalPlacesUsingStrrpos($stringValue){
    $locale_info = localeconv();
    $pos = strrpos($stringValue, $locale_info['decimal_point']);
    if ($pos !== false) {
        return strlen($stringValue) - ($pos + 1);
    }
    return 0;
}
