There are many questions on here asking how to separate the header of a cURL response from the body and the two methods I've seen are:
Use the length of the header and substr()
Use explode(" ", $response, 2)
However, the first method doesn't work when a proxy server is being used, and the second doesn't work when a 302 redirect is performed by the server and FOLLOW_LOCATION is set.
Therefore, my following code is insufficient, as the additional headers end up in $body:
$data = explode("
", $response, 2);
$header = $data[0];
$body = $data[1];
My current line of thought is to put the above code in a loop and after each iteration check if the first part of $body is HTTP, as the headers always look like:
HTTP/1.1 100 Continue
HTTP/1.1 302 Moved Temporarily
HTTP/1.1 200 OK
If the first part of $body is HTTP/, then I would keep iterating, otherwise I would know that the headers had all been separated from the body. However, the downside I see to this is that if the body starts with HTTP/ (which I suppose is unlikely), then that would cause a major issue.
Is there a better solution than the one I'm currently thinking of pursuing?
As a side note, I'm doing this because I need to retrieve both the response body and header(s).
