I'd probably just put the information in the form like this...

<input type="text" name="userfirstname"
value="<?=$_POST['userfirstname']?>">


With regard to "<select>" form fields, I'd put the options into an array,
then use a "for" loop to test is the submitted information matched

$array = array('1','2','3');
$size=sizeof($array);
<select name="option1">
<?
for($i = 0; $i < $size; $i++)
{
echo("<option value=\"" . $array[$i] .
$select = ($_FORM['option1'] == $array[$i]) ? ' selected':'';
echo($select . "\">");
}
?>
