get_headers() Fails If PHP Configuration Sets allow_url_fopen == Off

It's probably obvious but the actual line number is 129 due to a debugging line I threw into the file.

Here's a patch that resolves the failing call to get_headers(). I implement a new function, private_upload_is_publicly_accessible($url) which uses cURL to test the 200 & 302 HEAD status codes.

Here's the driver code I used to test:

// test
$url_array[0]="http://lalalala.com/aosenuthasonetuh"; // fail
$url_array[1]="http://yourwebsite.com/files/favicon.ico"; // succeed

foreach ($url_array as $value) {
  echo "Processing $value\n";
  $result = private_upload_is_publicly_accessible($value) ? 1 : 0;
  print "result is $result\n";
}

Peace

UPDATE: See below for latest patch.

Bug fixes in the latest patch:

1) Status codes now recorded properly as strings and not integers
2) While(!feof($fp)) loop removed since comparing against headers other than the very first one might lead to incorrect results. It's also efficient.

Peace

Hi starbow,

You're welcome.

Honestly, I regret the confusion above (and in the patch) between the libCurl and PHP implementation. This represents my first foray into this functionality and the documentation represents my own confusion. I appreciate you letting me know it wasn't cURL--aside from minor embarrassment I've corrected a mistaken assumption.

Peace
