PHP循环数据

Question

I want to make the first row 'update' button link to A page and second row 'update' button link to B page, but when the PHP function loops it keep showing that both row 'update' button link to the same page.

<?php
    $conn = mysql_connect("localhost","root","");
    mysql_select_db("smart_train",$conn);
    $result = mysql_query("SELECT * FROM detail");
>
<table id="example1" class="table table-bordered table-striped">
    <thead>
          <tr>
             <th>Station Place</th>
             <th>Line1</th>
             <th>Line2</th>
             <th>Line3</th>
             <th>Station Code</th>
             <th>Opening Hours</th>
             <th>Parking</th>
             <th>Content Control</th>
          </tr>
    </thead>

<?php
                        $i=0;
                        while($row = mysql_fetch_array($result)) {
                        if($i%2==0)
                        $classname="evenRow";
                        else
                        $classname="oddRow";
                   ?>
                  <tr class="<?php if(isset($classname)) echo $classname;?>">   
                    <td> <?php echo $row["place"]; ?> </td>
                    <td id="station_line1"> <?php echo $row["line1"]; ?> </td>
                    <td id="station_line2"> <?php echo $row["line2"]; ?> </td>
                    <td id="station_line3"> <?php echo $row["line3"]; ?> </td>
                    <td id="station_code"> <?php echo $row["code"]; ?> </td>
                    <td id="station_opening"> <?php echo $row["opening"]; ?> </td>
                    <td id="station_parking"> <?php echo $row["parking"]; ?> </td>
                    <td>
                        <div class="btn-group">
                          <a href="station_detail _update1.php">
                          <button onclick="myFunction()" type="button" class="btn btn-warning">Update</button>
                          </a>
                          <a><button type="button" class="btn btn-default" id="content_control_or">or</button></a>
                          <a><button type="button" class="btn btn-warning">Delete</button></a>
                          <?php if(isset($message)) { echo $message; } ?>
                      </div>
                    </td>
                  </tr>
                   <?php
                    $i++;
                    }
                   ?>
</tbody>

Can someone help me to solve this problem? I'm quite new to programming.

You need to pass variable in anchor of that button to redirect on page where page name will be dependent of $i's value.

if($i%2==0){
{ 
   $classname="evenRow";
   $goesToPage='Page1.php';
 }
else{
   $classname="oddRow";
   $goesToPage='Page2.php';
}

     <a href="<?php echo $goToPage; ?>">
