Converting a number with comma as decimal point to

Question

I have a list of prices with a comma for a decimal point and a dot as the thousand separator.

Some examples:

12,30
116,10
1.563,14

These come in this format from a third party. I want to convert them to floats and add them together.

What is the best way to do this? number_format doesn't seem to work with this format, and str_replace seems like overkill, as I have to do it more that once on each number.

Is there are better way? Thanks.

Might look excessive but will convert any given format no mater the locale:

function normalizeDecimal($val, int $precision = 4): string
{
    $input = str_replace(' ', '', $val);
    $number = str_replace(',', '.', $input);
    if (strpos($number, '.')) {
        $groups = explode('.', str_replace(',', '.', $number));
        $lastGroup = array_pop($groups);
        $number = implode('', $groups) . '.' . $lastGroup;
    }
    return bcadd($number, 0, $precision);
}

Output:

.12           -> 0.1200
123           -> 123.0000
123.91        -> 12345678.9100
123 456 78.91 -> 12345678.9100
123,456,78.91 -> 12345678.9100
123.456.78,91 -> 12345678.9100
123 456 78,91 -> 12345678.9100
