How to remove HTTP headers from CURL response?

Question

I have a php script that returns just plain text without any html. Now I want to make a cURL request to that script and I get the following response:

<

Answer 1

Just for a later use if anyone else needs. I was into same situation, but just need to remove header text, not content. The response i was getting in the header was (including white space):

HTTP/1.1 200 OK
Cache-Control: private, no-cache, no-store, must-revalidate
Content-Language: en
Content-Type: text/html
Date: Tue, 25 Feb 2014 20:59:29 GMT
Expires: Sat, 01 Jan 2000 00:00:00 GMT
Pragma: no-cache
Server: nginx
Vary: Cookie, Accept-Language, Accept-Encoding
transfer-encoding: chunked
Connection: keep-alive

I wanted to remove starting from HTTP till keep-alive with white space:

$contents = preg_replace('/HTTP(.*)alive/s',"",$contents);

that did for me.

Answer 2

If someone already saved the curl response to a file (like me) and therefore don't know how big the header was to use substr, try:

$file = '/path/to/file/with/headers';
file_put_contents($file, preg_replace('~.*\r\n\r\n~s', '', file_get_contents($file)));

Answer 3

Update the value of CURLOPT_HEADER to 0 for false

curl_setopt($ch, CURLOPT_HEADER, 0);

Answer 4

Make sure you put set the header flag:

        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_HEADER, true );
        curl_setopt($ch, CURLOPT_TIMEOUT, Constants::HTTP_TIMEOUT);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, Constants::HTTP_TIMEOUT);
        $response = curl_exec($ch); 

Do this after your curl call:

$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$headerstring = substr($response, 0, $header_size);
$body = substr($response, $header_size);

EDIT: If you'd like to have header in assoc array, add something like this:

    $headerArr = explode(PHP_EOL, $headerstring);
    foreach ($headerArr as $headerRow) {
        preg_match('/([a-zA-Z\-]+):\s(.+)$/',$headerRow, $matches);
        if (!isset($matches[0])) {
            continue;
        }
        $header[$matches[1]] = $matches[2];
    }

Result print_r($header):

(
    [content-type] => application/json
    [content-length] => 2848
    [date] => Tue, 06 Oct 2020 10:29:33 GMT
    [last-modified] => Tue, 06 Oct 2020 10:17:17 GMT
)

Don't forget to close connection curl_close($ch);

Answer 5

Just set CURLOPT_HEADER to false.

Answer 6

Just do not set the curl_header in the curl request or set it to z or false
like this
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_HEADER, false);
