Answer 1

$url='https://graph.microsoft.com/v1.0/me/drive/root:/filename:/createUploadSession';

    $data= '{}';
    $header = array('Content-Type: json',
        "Cache-Control: no-cache",
        "Pragma: no-cache",
        "Authorization: bearer {Access Token}");
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, TRUE);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $header );
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

get the uploadURL from the result,

    $graph_url = $result['uploadUrl'];
    $fragSize = 320 * 1024;
    $file = file_get_contents($filename_location);
    $fileSize = strlen($file);
    $numFragments = ceil($fileSize / $fragSize);
    $bytesRemaining = $fileSize;
    $i = 0;
    $ch = curl_init($graph_url);
    while ($i < $numFragments) {
        $chunkSize = $numBytes = $fragSize;
        $start = $i * $fragSize;
        $end = $i * $fragSize + $chunkSize - 1;
        $offset = $i * $fragSize;
        if ($bytesRemaining < $chunkSize) {
            $chunkSize = $numBytes = $bytesRemaining;
            $end = $fileSize - 1;
        }
        if ($stream = fopen($filename_location, 'r')) {
            // get contents using offset
            $data = stream_get_contents($stream, $chunkSize, $offset);
            fclose($stream);
        }

        $content_range = " bytes " . $start . "-" . $end . "/" . $fileSize;
        $headers = array(
            "Content-Length: $numBytes",
            "Content-Range:$content_range"
        );
        curl_setopt($ch, CURLOPT_URL, $graph_url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, constant('CURL_SSL_VERIFYPEER_STATUS'));
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        $server_output = curl_exec($ch);
        $info = curl_getinfo($ch);

        $bytesRemaining = $bytesRemaining - $chunkSize;
        $i++;
    }

And when you passing the last set of data it should be the correct data bytes. Otherwise it will fail the upload session.
