$post_data = 'var1=123&var2=456';

$content_length = strlen($post_data);

header('POST http://localhost/testing/test.php HTTP/1.1');

header('Host: localhost');

header('Connection: close');

header('Content-type: application/x-www-form-urlencoded');

header('Content-length: ' . $content_length); 

header($post_data);

but my code doesn't work properly. help me...

Answer 1

POST data forms the body of an HTTP request, it isn't a header, and the header method is used in making HTTP responses.

askapache has an example of making a POST request from PHP using the curl library.

Answer 2

You're trying to put request headers into answer. Client just don't know what to do with it.

What you are trying to achieve is impossible.

What is the task you're trying to accomplish? There can be another way.

Answer 3

If you're trying to post a request to remote server, you'll need to use a tool like cUrl. Here's an exmple:

// Create a curl handle to a non-existing location
$ch = curl_init('http://localhost/testing/test.php');

// Set options
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute
$page = curl_exec($ch); 

Alternatively, if you really want to put data in the headers, you can set custom headers using something like this:

curl_setopt($ch, CURLOPT_HTTPHEADER, array('field: value', 'field2: value') );
