I don't exactly understand what you want to do but I hope this will
help ypu getting your values:
<!-- *snip* -->
<html>
<form action="NewFile.php" method="POST">
<?
for($i=0;$i<5;$i++){
echo"<select name=\"test[]\">";
echo"<option value=\"1\">1</option>";
echo"<option value=\"2\">2</option>";
echo"<option value=\"3\">3</option>";
echo"</select>";
}
?>
<INPUT type="submit">
</form>
<?
# this will show you all values that are in $_POST
echo '<pre>', print_r($_POST), '</pre>';
# extract the array that contains all 5 values of the drop downs
$your_data = $_POST["test"];
# display the array
echo '<pre>', print_r($your_data), '</pre>';
# run through the array
foreach ($your_data as $value_from_array)
{
# ...and do with the values whatever you want to do
if ($value_from_array==5)
{
// instructions
# :-)
}
}
?>
</html>
