Archive x.htm
<form name="xx" method="post" action="probe.php">
<input type="checkbox" value="1" OnClick="javascript:document.xx.submit();" <?php if ($_POST[checkbox]==1) { print "CHECKED"; } ?>>
<iframe>
   <form name="xx" method="post" action="probe.php">
      <input type="checkbox" value="1" OnClick="javascript:document.xx.submit();" <?php if ($_POST[checkbox]==1) { print "CHECKED"; } ?>>
   </form>
</iframe>
</form>

probe.php 
<?php
print_r($_POST);
require("x.htm");
?>

When I execute this code in Apache 2 under windows 2000, then the result of the first time is correct, outside the iframe and inside it, but the second or the third time, the result it like this ARRAY(checkbox=1)ARRAY(checkbox=1)ARRAY(checkbox=1)ARRAY(checkbox=1)ARRAY(checkbox=1)ARRAY(checkbox=1)ARRAY(checkbox=1)..., and the the OS send me an apache memory error, but the apache still running.
