title: $_FILES['myfile']['error'] is zero, but there's no file uploaded
body: <p>I'm trying to copy a production server onto an old Mac running 10.5. Everything works great, except uploading files.</p>
  
  <p>Unfortunately, there are no errors being reported either by PHP or apache, just no file at the end. I've been setting permissions of everything I can find to 777, but no luck - even the simplest uploader tutorial produces a $_FILE['myfile']['error'] of zero, but when I look for the file listed in $_FILE['myfile']['tmp_name'] the file does not exist.  </p>
  
  <p>Any suggestions?</p>
  
  <p>I've tried the built-in OSX versions of apache and PHP 5.2, and I've tried installing apache2 and PHP 5.3.4 from MacPorts. Both have the same results.</p>
  
  <p>I figure this must be a permissions problem some place, but why don't I get an error?</p>
