Answer 1

In your question you have

    curl_setopt($curl, CURLOPT_FILE, $fp);

    curl_setopt($curl,  CURLOPT_RETURNTRANSFER, TRUE);

but from PHP's curl_setopt documentation notes...

It appears that setting CURLOPT_FILE before setting CURLOPT_RETURNTRANSFER doesn't work, presumably because CURLOPT_FILE depends on CURLOPT_RETURNTRANSFER being set.

So do this:



not this:

...stating "CURLOPT_FILE depends on CURLOPT_RETURNTRANSFER being set".
