Description:
------------
On requesting POST data using $_POST or $_REQUEST that
is being sent using Macromedia Flash MX, the last
character of the last request is missing. Work around
is to send a dummy variable as the last request.

Reproduce code:
---------------
<?
$filePath = stripslashes($_REQUEST["cmsFilePath"]);
$fileDataTotal = stripslashes($_REQUEST["cmsFileDataTotal"]);
$fileData = " ";
for ($counter = 0; $counter < $fileDataTotal; $counter ++){
$newPart = stripslashes($_REQUEST["cmsFileData".$counter]);
$fileData = $fileData.$newPart;
}
$fileName = stripslashes($_REQUEST["cmsFileName"]);
$test = stripslashes($_REQUEST["cmstest"]);
$start = time();
while (time()<($start +5)) {
}
$tfile = $filePath."/".$fileName;
touch($tfile);
chmod($tfile, 0666);
$handle = fopen($tfile, "wb");
fwrite($handle, $fileData.$test);
fclose($handle);
?>

Expected result:
----------------
the $test variable should contain the string "hello"

Actual result:
--------------
the $test variable actually contains "hell"
All other variables are ok.

<?php
var_dump(ini_get("register_globabls"));

Will tell you if you have register_globals enabled.

As for the space, make sure you have no spaces before the <?php (or <?)
in your script.

thanks for your help on this;
1) I am using it as CGI already.
2) The first charater is present and correct. I am
getting an un-asked-for " " at the beginning of my
file, though.
3) Not sure about this. I haven't been using PHP for
very long. how can I check for it?

1) Are you using as isapi module or CGI, if you are using the isapi
module try CGI and see if the problem persists.
2) Is the 1st character of the last variable missing when you use
$_POST?
3) Do you have register_globals enabled or disabled?

have just tried this but seems to make no difference.
Any ideas? It's IIS 5.1 if that helps.

Try to make a simple script just to see if the bug is particular to the
script you are using or any POST request. I find it extremely unusual
that _POST contains correct data while _REQUEST does not, since
_REQUEST is built using data from _POST.

no, still open. That Doh! was for something else.

There is still a problem with the last POST variable
requested missing it's last character.

I could, of course just add an extra character, or
dummy variable, but I'd rather know if I'm working
around a feature or a bug, or if I'm simply doing
something wrong?

register globals is Off

Worked out the space thing. Doh!
had a line specifically adding it:
$fileData = " ";
