Strange Upload Problem

[Ian Hardcastle]

I am creating a php script that I can call from a delphi program, this
itself is easy as I have already done this. The problem lies within
the php script, here is the code that DOESN'T work:

<?
$temp = $_POST['userid'];
$uppath = "users/$temp";
clearstatcache();
if(file_exists($uppath)){
unlink($uppath);
}
if(copy($imgname, $uppath)){
print("done_upload");
}else{
print("failed_upload");
}
?>

KEY: userid will be something like '5.jpg' without quotes, so uppath
will be something like 'users/5.jpg'.

This is the error responce from the script, sorry its in a raw state:

<br />
<b>Warning</b>: copy(users/5.jpg
): failed to open stream: Invalid argument in <b>C:\Program
Files\Apache Group\Apache2\htdocs\messenger\up.php</b> on line
<b>8</b><br />
failed_upload

NOW, if I hardcode the uppath to 'users/5.jpg' NOT using userid to
complete the path this works - Weird, example below:

<?
//$temp = $_POST['userid'];
$uppath = "users/5.jpg";
clearstatcache();
if(file_exists($uppath)){
unlink($uppath);
}
if(copy($imgname, $uppath)){
print("done_upload");
}else{
print("failed_upload");
}
?>
I can't understand why I can hardcode the path, which is the same as
the one made up using the userid, and it works perfect.

The path I make using userid when printed out is correct and the file
exists cos I have checked this using a file_exists() check.

Any help is appreciated

Thanks

Ian

Maybe there's some extra characters in the POST variable
$temp = trim($temp);

$uppath = "users/$temp";

Thanks Pedro the trim() function seemed to fix the problem. There must
have been some invalid characters or blank space that didn't show up
when output so the comparison looked the same.

Thanks again, if only all problems were as simple to fix.
