    Filters to be used within the convert filter are base64-encode, base64-decode, quoted-printable-encode and quoted-printable-decode. Note: those are not in the string filter, as currently reported by the manual!

    Example usage is:
    <?php
    $h     = fopen('gecodeerd.txt', 'r');
    stream_filter_append($h, 'convert.base64-decode');
    fpassthru($h);
    fclose($h);
    ?>
    Or
    <?php
    $filter     = 'convert.base64-decode';
    $file = 'coded.txt';
    $h = fopen('php://filter/read=' . $filter . '/resource=' . $file,'r');
    fpassthru($h);
    fclose($h);
    ?>
