My drop down is showing blank then when i select the value of dropdown the same value is showing, but i have to show dropdown value as select first then when I click on button the respective value should show

I am doing a Php program

php $_PHP_SELF?>"> for="courseDisp" class="col-sm-2" style="margin-top:10px;">Course : php $course="SELECT * from course"; $res= $conn->query($course); if($res->num_rows>0) { echo ''; } else { echo "0 result"; } ?> &nbsp;&nbsp; for="yearDisp" class="col-sm-2" style="margin-top:10px;">Year : php $year="SELECT distinct(year) from syllabus"; $res= $conn->query($year); if($res->num_rows>0) { echo ''; } else { echo "0 result"; } ?> <script type="text/javascript"> document.getElementById('courseDisp').value = "php echo $_POST['courseDisp'];?>"; document.getElementById('yearDisp').value = "php echo $_POST['yearDisp'];?>";

                                                    <input type="submit" class="btn col-sm-2" style="margin-left:15px;margin-top:10px;width:60px;font-weight:bold;font-size:15px;" value="GO" name="btnGo" id="btnGo" />
