Question

I am using PHP http_post_data() call to send data to a cakephp controller.I do it like this:

$response=http_post_data($url, $xml_data_encoded);

The data arrives ok to the destination and I get a response which holds the response status.In my case the status is number 1 which means -data delivered ok.As you can see from the code below I get not only the status number (which is at the bottom of the message) but also the whole http post header.How can I strip this message off the header code so that eventually the response message holds only the status number?

HTTP/1.1 100 Continue
HTTP/1.1 200 OK

Btw, I also tried this:

 HttpMessage::getBody(http_post_data($url, $xml_data_encoded));

and got no response at all.
Any help will be highly appreciated.

Answer 1

$response = http_post_data($url, $data);
preg_match_all('~HTTP/1\.[01]\s(\d{3})~', $response, $codes);

$codes would store all matches. Just print_r the array and look for desired keys.
