在php表单模板变量中嵌入php函数

I'm trying to use a php function within a template html form that is being assigned as a php variable. I know that I can use standard $ variables and they will display ok, but I don't know how to use a function.

Essentially, I have a database with a set of values that I want to use to populate a drop down select form. I need to display the form in a couple of places so it makes sense to template the form with a variable.

So far I have the following PHP. Any help would be gratefully received! The array works fine - but displaying it within the form I'm struggling with.

$query = "SELECT 
  property.propertyid,
  property.reference,
  property.userid, 
  users.userid,
  users.username
FROM 
  property
    LEFT JOIN users ON property.userid = users.userid
WHERE 
  property.userid = ".$varuserid."
  ";

$result = mysql_query($query) or die(mysql_error());
$listarr=array();  
while($qy = mysql_fetch_array($result)){
$listarr[] = "<option value=\"".$qy['propertyid']."\">".$qy['reference']."</option>";
}

$form = <<<HTML
<form name="insert" method="post" action="?page=account&amp;a=insert&amp;form=1">
  <table width="100%" border="0" cellpadding="4" cellspacing="0">
    <tr> 
      <td width="24%" align="left" valign="top">Property ID</td>
      <td width="76%">      
        <select name="propertyid" size="1">

foreach($listarr as $key => $value) { echo $value }

        </select>
      </td>
    </tr>
    <tr> 
      <td align="left" valign="top">&nbsp;</td>
      <td>
      <input name="userid" type="hidden" id="userid" value=$varuserid />
      <input type="submit" name="submit" value="Insert transaction!" /></td>
    </tr>
  </table>
</form>
HTML;

Thanks, Simeonenter code here

    You cannot use a loop inside a heredoc but you can use variables.

    As you already have your list, what you can do is:

    while($qy = mysql_fetch_array($result)){
    $listarr[] = "<option value=\"".$qy['propertyid']."\">".$qy['reference']."</option>";
}
$list = implode(" ", $listarr);

    And in your heredoc:

    <select name="propertyid" size="1">
    {$list}
</select>

    Edit: Note that you need to do that for all variables you include in the heredoc, so:

    <input name="userid" type="hidden" id="userid" value={$varuserid} />
                                                     ^          ^
