Get Checkbox value for edit data PHP

<td align="center"><input type="checkbox" name="checked_id[]" class="checkbox" value="<?php echo $id_student;?>"/></td>


<button type="button" class="btn btn-lg btn-success" onClick="window.location = 'edit.php?ktp=<?php echo $id_student; ?>'">EDIT</button

How can i get the value of the checkbox for use on other php page like edit.php? Id_student = 3454? My results may differ from the checkbox value I choose.
