Populating drop down list in the PHP variable

Issue

    while ($row = mysqli_fetch_array($result)){
      $move = '
        <select type = text name="mover">
         <option>select something</option>
          '".while ($dbrow = mysqli_fetch_array($result)){
              echo "<option value='".$dbrow['deptname']."'>".$dbrow['deptname']."</option>";}."'
        </select>';

    echo '<tr><td>'.$row['name'].'</td><td>'.$move.'</td></tr>';}

I am trying to display dropdown list inside the table. However whenever I apply while(...) codes, it displays an error.

shouldn't HTML + '".PHP."' + HTML be the correct way?

Solution

Generate the select menu before entering the main loop that builds the table and then rewind the recordset so that the main loop can begin

<?php
    $html='<select name="mover">
        <option selected disabled hidden>Please select something';
        
    while( $row = mysqli_fetch_array( $result ) ){
        $html.=sprintf('<option>%s',$row['deptname'] );
    }
    
    $html.='</select>';
    $result->data_seek(0);
?>

Then build the table.

<table>
<?php
    while( $row = mysqli_fetch_array( $result ) ){
        printf('<tr><td>%1$s</td><td>%2$s</td></tr>',$row['deptname'],$html);
    }
?>
</table>
