Bagaimana memanggil variabel dari file a dan di cetak di file b tanpa button

 <?php
                $total['kkm'] = $total['kkm']+$row['kkm'];
                $total['ratarata'] = $total['ratarata'] + $row['ratarata'];
                $total['uts'] = $total['uts']+$row['uts'];
                $total['uas'] = $total['uas']+$row['uas'];
                $i++;

                $totalratarata=$total['ratarata']/$i;
                $totaluts=$total['uts']/$i;
                $totaluas=$total['uas']/$i;
              }
              ?>

              <!-- RATA RATA -->
            <tr style="background-color:#000">
               <td><b>RATA RATA</b></td>
               <td><b><?php echo ($total['kkm']/$i); ?></b></td>
               <td><?php echo $totalratarata; ?></td>
               <td><?php echo $totaluts; ?></td>
               <td><?php echo $totaluas; ?></td>
           </tr>

yang di RATA RATA itu hasil hitung otomatis yang mau saya cetak juga di file B

if ($hasil->num_rows > 0) {
                foreach ($hasil as $row) { ?>
          <tr>
                  <td><?php echo $no; ?></td>
                  <td><?php echo $row['nisnip']; ?></td>
                  <td><?php echo $row['nama']; ?></td>
                  <td><?php echo $row['kelas']; ?></td>
                  <td><?php echo $row['totalratarata']; ?></td>
                  <td><?php echo $row['totaluts']; ?></td>
                  <td><?php echo $row['totaluas']; ?></td>


          </tr>
            <?php
            $no++;
            }
              } else {
            echo mysqli_error($koneksi);
              } $koneksi->close();
            ?>

Terimakasih banyak
