Status: Bogus
Bug Type: PHP options/info functions
Operating System: Linux
PHP Version: 5.2.12
New Comment:
Then this function is no better than the safe mode, magic quotes and
similar fiascos of PHP - useless and will be avoided, at least by me.
The purpose of this function is to protect the server from DOS attacks.
Does the server need many resources to process the empty files? I would
guess not.
On the other hand this is very limiting for forms that wish to have
many _optional_ file upload input fields (which was how I stumbled
across this bug).
Anyway, I'll just be careful to choose a host with this "feature"
turned off in the future, the same as I did with safe mode. :(
Oh, and by the way, turning it on by default in the very first
incarnation of this option is not very nice IMHO. It took me quite some
time to figure out what is going on since there are almost no pages with
this setting described yet. :(

Of course it does, that's exactly it's purpose: to limit maximum number
of uploads. And yes, even "empty" upload is an upload.

Description:
------------
Setting max_file_uploads limits the number of file input fields on HTML
page instead of limiting the number of actually uploaded files.
Reproduce code:
---------------
<form name="formData" action="" enctype="multipart/form-data"
method="post">
<?php
for ($i=0;$i<30;$i++)
{
echo "File ".($i+1).":<br />\n".
'<input name="file_'.$i.'" type="file" /><br />'."\n";
};
?>
<input value="OK!" type="submit" />
</form>
<pre>
<?php var_dump($_FILES) ;?>
</pre>
Expected result:
----------------
When you upload a single file (in the LAST!!! input box) and hit "OK!",
you should see the uploaded file.
Actual result:
--------------
Instead you see just 20 empty file uploads. (if max_file_uploads is set
to 20, as per default)
The max_file_uploads setting should never count empty files.
