[RESOLVED] Append Iteration Number to Variable Name

[hskr74]

I'm drawing a blank on how to append the iteration number to the variable name..

if ( isset($_POST['multi_reg']) ) {
  for ($i=1; $i <= $_POST['multi_reg']; $i++) {
    echo "<LABEL FOR=lastname$i>Last name:</LABEL>";
    echo "<INPUT name=\"$lastname.$i\" value=\"
    if (isset($lastname.$i)) {
      echo $lastname.$i;
    }
    echo "\">";

basically, I ask the user how many people they want to register and then I want PHP to create that many text boxes and assign variables as such:
$lastname1
$lastname2
etc...

what syntax do I use to append the text "lastname" to the variable result $i and use it as a new variable name?

Thanks!

${'lastname' . $i}

But this is an often-seen newbie hack. Use arrays instead.
