Php cUrl как вывести возвращаемые заголовки?

После curl_setopt($ch, CURLOPT_HEADER, true) при curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) HTTP-header возвращается в теле ответа $html = curl_exec($ch) . Вот оттуда его и доставайте через

$html = curl_exec($ch); if ($html !== false)

curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($ch, CURLOPT_USERPWD, "name:password"); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST'); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($json)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_MAXREDIRS, 10); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.9.0.4) Gecko/2008102920 AdCentriaIM/1.7 Firefox/3.0.4"); curl_setopt($ch, CURLOPT_AUTOREFERER, 1); curl_setopt($ch, CURLOPT_HEADER, true); //curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY); // возможно curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt'); curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt'); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_TIMEOUT, 200); $result = json_decode(curl_exec($ch), true); $code = curl_getinfo($ch, CURLINFO_RESPONSE_CODE); $new_url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

Retrieve response headers from PHP cURL

There are two ways to get response headres from PHP cURL.

1. Using CURLOPT_HEADER option

With the curl_setopt() method, when CURLOPT_HEADER is set to true, curl_exec will output response header. At this time, if CURLOPT_NOBODY is set to false, curl_setopt() will return the response header and content body, otherwise only the response header will be returned.

We can use curl_getinfo($ch, CURLINFO_HEADER_SIZE) method to return total size of all headers received.

$url = "https://www.google.com"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 1); // TRUE to exclude the body from the output. curl_setopt($ch, CURLOPT_NOBODY, 0); $response = curl_exec($ch); // After curl_exec $header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE); $header = substr($response, 0, $header_size); $body = substr($response, $header_size); echo $header; // echo $body;

2. Using CURLOPT_HEADERFUNCTION option

With the CURLOPT_HEADERFUNCTION option, we can set a callback function.

$headers = []; $url = "https://www.google.com"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADERFUNCTION, function ($curl, $header) use (&$headers)  $len = strlen($header); $header = explode(':', $header, 2); if (count($header)  2) // ignore invalid headers return $len; $headers[strtolower(trim($header[0]))][] = trim($header[1]); return $len; > ); $response = curl_exec($ch); print_r($headers);
