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
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>";
