Erron in PHP7

[tarastalian]

There is an error in PHP 7. The lib it's always returning 'Malformatted' for every character, instead of the alphabet itself.
There is a problem in TextLanguageDetect, in the way the unicode compares to the hex of the blocks. It war working in PHP 5 but not in PHP 7.

        // your average binary search algorithm
        while ($low <= $high) {
            $mid = floor(($low + $high) / 2);

            if ($unicode < $blocks[$mid][0]) {
                // if it's lower than the lower bound
                $high = $mid - 1;

            } elseif ($unicode > $blocks[$mid][1]) {
                // if it's higher than the upper bound
                $low = $mid + 1;

            } else {
                // found it
                return $blocks[$mid];
            }
        }

I'd changed wiht this one to fix it

        // your average binary search algorithm
        while ($low <= $high) {
            $mid = floor(($low + $high) / 2);

            if ($unicode < hexdec($blocks[$mid][0])) {
                // if it's lower than the lower bound
                $high = $mid - 1;

            } elseif ($unicode > hexdec($blocks[$mid][1])) {
                // if it's higher than the upper bound
                $low = $mid + 1;

            } else {
                // found it
                return $blocks[$mid];
            }
        }

How do i make this changes accesible to everybody?
