PHP / MSSQL在下拉列表中显示存储的字段值

Question

I use the following code to create a number of drop-down lists with the same values. The values are brought in from an MSSQL table via a query written elsewhere.

<?php
 $select = '';
 while($row = $data->fetch(PDO::FETCH_BOTH))
 {
   $select .= "<option value='".$row['Code']."'>".$row['Code']."</option> ";
 }
 echo "<select name=\"proj1[]\">";
 echo $select;
 echo "</select>";
?>

The user makes his selections, then submits the form and the record is written to the PROJECTS table in the PROJ DB (fields: Proj1, Proj2, Proj3, Proj4). The original drop-down values are held in a separate table (CODES). When the record is called up in a browser, a prepared SELECT statement runs against PROJECTS to load it. I would like to show the user the drop-down selections he made when the completed form is loaded, ie, the values of Proj1-Proj4 for a given record in PROJECTS. How can I do this? I'm not sure where to put my 'option selected'.

Hope this help

 $select = '';
    while($row = $data->fetch(PDO::FETCH_BOTH))
    {
        $select .= "<option value='".$row['Code']."' '".$row['Code'] == $_POST['proj1'] ? ' selected="selected"' : ''."'  >".$row['Code']."</option> ";
    }
    echo "<select name=\"proj1[]\">";
    echo $select;
    echo "</select>";
