Get Header from PHP cURL response
79,464
Solution 1
It converts all headers into an array
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "example.com");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//enable headers
curl_setopt($ch, CURLOPT_HEADER, 1);
//get only headers
curl_setopt($ch, CURLOPT_NOBODY, 1);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
$headers = [];
$output = rtrim($output);
$data = explode("\n",$output);
$headers['status'] = $data[0];
array_shift($data);
foreach($data as $part){
//some headers will contain ":" character (Location for example), and the part after ":" will be lost, Thanks to @Emanuele
$middle = explode(":",$part,2);
//Supress warning message if $middle[1] does not exist, Thanks to @crayons
if ( !isset($middle[1]) ) { $middle[1] = null; }
$headers[trim($middle[0])] = trim($middle[1]);
}
// Print all headers as array
echo "<pre>";
print_r($headers);
echo "</pre>";
Solution 2
For the first answer note that the code:
$middle=explode(":",$part);
will produce wrong results with string data containing :
, like for example:
Sat, 14 Jan 2017 01:10:01 GMT
The correct code to split the fields to build the array would be like:
$middle=explode(":",$part,2);

I am new to PHP. I am trying to get the Header from the response after sending the php curl POST request. The client sends the request to the server and server sends back the response with Header. Here is how I sent my POST request.
$client = curl_init($url); curl_setopt($client, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($client, CURLOPT_POSTFIELDS, $data_string); curl_setopt($client, CURLOPT_HEADER, 1); $response = curl_exec($client); var_dump($response);
Here is the Header response from server that I get from the browser
HTTP/1.1 200 OK Date: Wed, 01 Feb 2017 11:40:59 GMT Authorization: eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1c2Vycy9CYW9CaW5oMTEwMiIsIm5hbWUiOiJhZG1pbiIsInBhc3N3b3JkIjoiMTIzNCJ9.kIGghbKQtMowjUZ6g62KirdfDUA_HtmW-wjqc3ROXjc Content-Type: text/html;charset=utf-8 Transfer-Encoding: chunked Server: Jetty(9.3.6.v20151106)
How can I extract the Authorization part from the Header ?. I need to store it in the cookies
