    In reply to daniel at danielphenry dot com example note beneath. The given example by Daniel returns false under PHP7.x, which is a normal behavior since NumberFormatter::parseCurrency() is a method for parsing currency strings. It is trying to split up the given string in a float and a currency.

    While using strict types under PHP7 the following example makes it more clearer.

    <?php
    declare(strict_types=1);
    namespace     MMNewmedia;

    $oParser = new \NumberFormatter('de_DE', \NumberFormatter::CURRENCY);
    var_dump($oParser->parseCurrency("1.234.567,89\xc2\xa0€", $currency), $currency));
    ?>

    This example returns: "float(1234567.89) string(3) "EUR"

    This is the expected behavior.

    The following example runs into a type error, which is absolutely right, since this method is vor parsing strings and not vor formatting floats into currency strings.

    <?php
    declare(strict_types=1);
    namespace     MMNewmedia;

    try {
            $oCurrencyParser = new \NumberFormatter('de_DE', \NumberFormatter::CURRENCY);
            $currency = 'EUR';
            var_dump($oCurrencyParser->parseCurrency(1.234, $currency), $currency);
    } catch (\    TypeError $oTypeError) {
            var_dump($oTypeError->getMessage());
    }
    ?>

    This example returns "NumberFormatter::parseCurrency() expects parameter 1 to be string, float given".

    If you want to parse floats into a currency string use the http://php.net/manual/en/numberformatter.formatcurrency.php method as shown in the next example.

    <?php
    declare(strict_types=1);
    namespace     MMNewmedia;

    $oFormatter = new \NumberFormatter('de_DE', \NumberFormatter::CURRENCY);
    var_dump($oFormatter->formatCurrency(1234567.89, 'EUR'));
    ?>

    This returns string(17) "1.234.567,89 €" as expected.
