And what exactly do you have in the extra.php script??

Replace that script with this:

<?php

var_dump($_FILES);

?>

And post the output here (when you upload the problem file to it)

I created a simplified version with the code you wanted.
Here are the links, with the source.

I got the same results.

Works just fine, I've uploaded "a b.html" and it worked perfectly.

Actually ilia, your test case doesn't match his bug report, but I did a test case which did:

Uploaded a file from  C:\Documents and Settings\pollita\Desktop\test.png

I got exactly what I'd have expected from the form.

array(1) { 
  ["userfile"]=> array(5) { 
    ["name"]=> string(8) "test.png" 
    ["type"]=> string(10) "text/plain" 
    ["tmp_name"]=> string(14) "/tmp/phpuuE33H" 
    ["error"]=> int(0) 
    ["size"]=> int(11) 
  } 
}

Try the same test whith an image.

I mean a .jpg.

The extension on the file name would make absolutely no difference (and I invite you to read RFC 1867 to learn why), but to humor you I'll give it a shot.

Uploading: C:\Documents and Settings\pollita\Desktop\php_logo.jpg

<?php print_r($_FILES); ?>

array(1) { 
  ["userfile"]=> array(5) { 
    ["name"]=> string(8) "php_logo.jpg" 
    ["type"]=> string(10) "image/jpeg" 
    ["tmp_name"]=> string(14) "/tmp/phpiwC27H" 
    ["error"]=> int(0) 
    ["size"]=> int(1469) 
  } 
}


Something is wrong with your script, or with an assumption you've made in processing your file.  Please post your question to the generals mailing list for further assistance.
