PHP: Set custom headers with cURL.
In this guide, we will show you how to set custom request headers with PHP’s cuRL extension.
We can change header values pretty easily using the CURLOPT_HTTPHEADER option.
For example, we could modify the Referer, Cookie, User-Agent or Accept-Encoding headers.
Take a look at the following cURL request:
//The URL you're sending the request to. $url = 'http://localhost/test/file.php'; //Create a cURL handle. $ch = curl_init($url); //Create an array of custom headers. $customHeaders = array( 'Accept-Encoding: gzip, deflate, br', 'Cookie: PHPSESSID=ciqas3vp82m514iubpr1b0md3o;', 'Referer: https://www.google.com/' ); //Use the CURLOPT_HTTPHEADER option to use our //custom headers. curl_setopt($ch, CURLOPT_HTTPHEADER, $customHeaders); //Set options to follow redirects and return output //as a string. curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); //Execute the request. $result = curl_exec($ch); echo $result;
In the PHP code above, we sent a GET request to a localhost URL.
We also created a PHP array called $customHeaders, which contains all of the custom headers that we want to send.
In this case, we set three custom headers using the CURLOPT_HTTPHEADER option:
- We set the “Accept-Encoding” header to gzip, deflate and br (Brotli).
- We provided a PHPSESSID value as the “Cookie” header.
- Finally, we set the HTTP referer to a Google search URL. This is called referrer spoofing.
If you send this cURL request to a PHP script that prints out the $_SERVER array, you will see something like this:
In the screenshot above, you can see that the script has received our headers:
- The “Accept-Encoding” header is HTTP_ACCEPT_ENCODING.
- Cookie is HTTP_COOKIE.
- Referer is HTTP_REFERER.
Using an array as request headers in PHP
I need to add API keys to the headers of my request, I’m storing these in an array so I easily edit them later and use them in multiple functions. Is there any method to send data without curl on third party server which receiving on headers parameters.
Using an array as request headers in PHP
I’m trying to send a GET request to an API using PHP stream_context_create and file_get_contents .
I need to add API keys to the headers of my request, I’m storing these in an array so I easily edit them later and use them in multiple functions. What is a good way to include these arrays as headers?
In this case the key of the array would be the header keys and the value of the array the value of the header.
Some code to explain the problem
"id", "X-Api-Key" => "key", "X-Api-Secret" => "secret" ); $options = array( "http" => array( "header" => "Content-type: application/x-www-form-urlencoded\r\n", // here I need to add the $api array "method" => "GET" ) ); return file_get_contents("example.com", FALSE, stream_context_create($options)); ?> Simply add the info to the header.
'id', 'X-Api-Key' => 'key', 'X-Api-Secret' => 'secret', ]; $headerData['Content-type'] = 'application/x-www-form-urlencoded'; $headerData = array_merge($headerData, $api); array_walk($headerData, static function(&$v, $k) < $v = $k.': '.$v; >); $options = array( 'http' => [ 'header' => implode("\n", $headerData), 'method' => 'GET' ] ); return file_get_contents('example.com', FALSE, stream_context_create($options)); ?> To encode the data you can use http_build_query(). To add it to the header options you should be able to do something like:
$options = array( "http" =>array( 'method' => 'POST', // GET in your case(?) 'header' => 'Content-type: application/x-www-form-urlencoded', 'content' => http_build_query($api) ) ); PHP GET Request, sending headers, If you’re using cURL, you can use curl_setopt ($handle, CURLOPT_USERAGENT, ‘browser description’) to define the user-agent header of the

Get Cookie Value From HTTP GET Request Header String
I’m trying to get the cookie value from the HTTP get request string. How can I handle the request header string and get the cookie value in it? Is there any method to use or any different solution to handle it?
= 1) < $data = unmask($data); $data = json_decode($data); $action = $data->action; if (isset($data->action) && $action == 'connect') < foreach ($agents as $key =>$value) < if ($key == $agentid && $value != $accept) < socket_close($value); $agents[$key] = $accept; >> > break; //exist this loop > > while (true); This is the way that I’m getting the header string from the HTTP get request.
This is the method that how I parse the header string.

How to send data in http headers in php for calling another server Api
I have to call third party API which I need to send data in headers I am trying in cURL.
Is there any method to send data without curl on third party server which receiving on headers parameters.
This is what am trying but not succeed:
$MobileNo=$_POST['MobileNo']; $SMSText=$_POST['SMSText']; $remarks=$_POST['remarks']; $RequestNo=$_POST['RequestNo']; $headers = array ( 'MobileNo', $MobileNo, 'RequestNo', $RequestNo, 'SMSText', $SMSText, 'Content-Type: application/text' ); $ch = curl_init(); curl_setopt( $ch,CURLOPT_URL, 'http://example.com/api/SendEnglishSMS' ); curl_setopt( $ch,CURLOPT_POST, true ); curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers ); curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true ); curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false ); $result = curl_exec($ch ); curl_close( $ch ); echo $result; I want to send data as well as receive the response from the third server request.
You can try below code. Hope, it will help you.
$headers = array ( 'MobileNo:'.$MobileNo, 'RequestNo:'.$RequestNo, 'SMSText:'.$SMSText, 'Content-Type: application/json' ); How do I send a GET request with a header from PHP?, You may use file_get_contents if you don’t want to use curl but not sure about speed but it’s php ‘s built in function where curl is not.
Setting custom headers with PHP.
This is a guide on how to set custom HTTP response headers using PHP. This can be useful if you need to tell the client something without outputting it in the body response.
Take a look at the following example:
//Setting a custom header with PHP. header('HeaderName: HeaderValue'); In the code above, we created a HTTP response header called “HeaderName” and gave it the value “HeaderValue”. If you open up your developer tools and inspect the request, you should see something like this:
A screenshot from Google Chrome’s developer tools showing our custom header.
Note that this header will not be available in the $_SERVER superglobals array. This is because in most case, the web server has already finished processing the incoming request by the time your PHP code is executed.
However, you will see it if you use the headers_list function like so:
//Setting a custom header with PHP. header('HeaderName: HeaderValue'); //var_dump the headers_list() function. var_dump(headers_list()); If you run the PHP script above, you will see that the headers_list function returns an array of headers that were sent to the browser.
Custom headers can be especially useful if you have a caching system in place and you’d like to tell the client if they are retrieving a cached resource or not. For example: Was the data retrieved from Memcached or was it retrieved from MySQL? Did the file exist already or did your PHP script have to generate it dynamically?
These are just a few examples of why a custom header might come in handy.
