Hello all,
I am trying to write a script in PHP. A simple calculator! (Just learning PHP)
anyways,
I think my code is fine (I think)but I still get the following error:

Parse error: parse error, unexpected $ in /home/virtual/site2/fst/var/www/html/calculate.php on line 33

Can someone help me out to figure out the problem? I am running this code off my servers that is supposed to have PHP installed.
Thanks

here is the code:

<?
if (($val1=="") || ($val2=="") || ($calc=="")) {
header("Location: http://www.sefati.com/test.html");
exit;

if ($calc=="add")
{
$results=$val1+$val2;
}
else if ($calc=="subtract")
{
$results=$val1-$val2;
}
else if ($calc=="multiply<")
{
$results=$val1*$val2;
}
else if ($calc=="divide")
{
$results=$val1/$val2;
}
?>

Calculation Results

The result of calculation is: <? echo "$result"; ?>

just something for you to consider: speed and efficiency. if this isn't something where you're calculating something that you store based on user input, it's faster to use javascript.

php is very strong, but there are times when it's not the best tool for the job. any calculating you don't need to store, chances are javascript is better.

POSIX. because a stable os that doesn't have memory leaks and isn't buggy is always good.

a word of advice, don't get in the habit of relying on register_globals. fetch your query info yourself:

<?php
    $val1 = &$_GET['val1'];
    $val2 = &$_GET['val2'];
    $calc = &$_GET['calc'];
?>
