使用PHP从MSSQL数据填充选择框

Question

I've searched and found some answers that are close, but not quite what I need. I'm hoping someone here can point me in the right direction.

I have a work assignment that I don't fully know how to do. I have a basic knowledge of PHP and SQL, but a solid understanding of HTML and CSS.

SO, I built a beautiful web form with lots of select boxes. Some will pull data right from a MS SQL database. When submitted, some will push data back into the database. For this question I wan to focus on pulling from the DB.

I did get the PHP page connected to the database, but getting the select boxes to populate is giving me a real hard time. I want to learn how to do this.

My form page is calling a config.php file with the connection info like this:

<?php
//Require config file with DB connection details
require_once('config.php');
?>

My config file looks like this:

<?php
$serverName = "xxxxxxxxx\xxxxxx"; //serverName\instanceName
$connectionInfo = array( "Database"=>"xxxxx", "UID"=>"xxxxx", "PWD"=>"xxxxx");
$conn = sqlsrv_connect( $serverName, $connectionInfo);

if( $conn ) {
 echo "Congratulations! Your DB connection has been established.<br />";
}else{
 echo "Connection could not be established.<br />";
 die( print_r( sqlsrv_errors(), true));
}
?>

My page displays the message that the connection is successful. My big question is this, what else to I have to put on my form page to get it to display data in a select box?

Here what i was trying but isnt working...

<?php
//Require config file with DB connection details
require_once('config.php');

$result = mssqli_query($con,"SELECT * FROM Auditors ORDER BY ID");

while($row = mssqli_fetch_array($result))
  {
  echo $row['AuditorName'];
  echo "<br>";
  }

mysqli_close($con);
?>

And then the select box code:

<select name="auditor" id="auditor">
<?php foreach ($result as $row): ?>
    <option><?=$row["Auditor"]?></option>
    <?php endforeach ?>
</select>

Can anyone tell me what I'm doing wrong and maybe post an example of what WILL work? Once I get this part figured out, I have several other select boxes to apply it to, so this will be a great help.

The above code gets me a blank page with only my successful DB connection message. My whole form disappears and there is no error message.

Thanks in advance for your time, Jason

Instead of using both while and foreach you can make it work by bringing your while loop down

<select>
<?php
while($row = mssqli_fetch_array($result))
{  
   echo '<option>' . $row["Auditor"] . '</option>';
}
?>
</select>

<?php
   mysqli_close($con);
?>
