You have to look at the headers
Exactly...submit the form and the HEADER version of the string returns "a:0:{}"
But, a print() of the same string variable correctly returns
"a:1:{s:3:"foo";s:3:"bar";}"
Dig deeper into it :) I had to use the Developer tools plugin in Firefox to get the
HTTP Headers that were returned :)
Compare those two, and boggle the mind ;)
Thanks!
Eric

Exactly what part of this is confusing you?
When you first request the page, $_POST is empty, so you end up with a serialized
value of "a:0:{}" which has a length of 6.
When you submit the form, you end up with a serialized value of:
a:1:{s:3:"foo";s:3:"bar";}
which has a length of 26. Maybe I missed something in this thread, but what's the
issue here?

for some reason and I'm too lazy to add them myself. :)

Check this out:
bash-2.05$ cat test.php
<?php
function jpcache_debug2($s2)
{
$length = strlen($s2);
$length++;
$headers = "X-CacheDebug-five: $length";
header($headers);
print $length . "\n";
print strlen($s2);
}
$myVariable = serialize($_POST);
jpcache_debug2($myVariable);
?>
<html>
<body>
<form method="POST" action="test.php" enc-type="multipart/form-data">
<input type="hidden" name="foo" value="bar">
<input type="submit" value="blah">
</form>
</body>
</html>
bash-2.05$

How the bloody hell is $length being treated differently?
Thanks,

Try to use unserialize();
