Get Header from PHP cURL response
提问by Tuan Dinh
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.
我是 PHP 新手。我试图在发送 php curl POST 请求后从响应中获取 Header。客户端向服务器发送请求，服务器返回带有 Header 的响应。这是我发送 POST 请求的方式。
$client = curl_init($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

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
它将所有标题转换为数组
// 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>";

For the first answer note that the code:
对于第一个答案，请注意代码：
$middle=explode(":",$part);
will produce wrong results with string data containing :, like for example:
使用包含 的字符串数据会产生错误的结果，:例如：

The correct code to split the fields to build the array would be like:
拆分字段以构建数组的正确代码如下：
$middle=explode(":",$part,2);

You just include this coding into your curl request
您只需将此编码包含在 curl 请求中
curl_setopt($curl_exec, CURLOPT_HEADER, true);
curl_setopt($curl_exec, CURLOPT_NOBODY, true);
after your curl execution use $header_data= curl_getinfo($curl_exec);
在 curl 执行使用后 $header_data= curl_getinfo($curl_exec);
Then you get all the headers
然后你得到所有的标题
print_r($header_data);
or use the shell_exec
或使用shell_exec
echo shell_exec("curl -I http://example.com ");

just use simple code to convert curl response to array.
只需使用简单的代码将 curl 响应转换为数组。
$response = curl_exec($ch);
$header_data= curl_getinfo($ch);
print_r($header_data);
