Possible to add data to the body of a HTTP request using cURL in PHP?

Question

I would like to add some data to the body of a http request using cURL in PHP.

Is this possible? How?

I'm sending a HTTP request to a remote server. I have added all the headers I want, but now I need to add some more data to the HTTP body but I cant figure out how to do it.

It is supposed to look something like this:

Host: stackoverflow.com
Authorization: Basic asd3sd6878sdf6svg87fS
User-Agent: My user agent
... other headers...  

I want to add data to the request here

Answer 1

You'll want to look at curl and more specifically curl_setopt.

If you can be more exact about your needs, I can provide an example for you, although the examples on the manual page are quite good to get you started also.

Answer 2

You can only add the post values when sending a post request with the CURLOPT_POSTFIELDS option.

Answer 3

Not 100% sure what you mean...

If you want to grab a page, and replace the content/insert some content to it - you could do something like this:

$ch = curl_init("http://stackoverflow.com/questions/1361169/possible-to-add-data-to-the-body-of-a-http-request-using-curl-in-php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
$output = curl_exec($ch);

$output = str_replace('Possible to add data to the body of a HTTP request using cURL in PHP?', 'I have just changed the title of your post...', $output);

echo $output;

This would print this page...

EDIT:

With the new information added, I do think you should be able to use the POSTFIELDS.. Just remember to set the POST to 1..

E.g. (something like this - not tested)

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://stackoverflow.com");
curl_setopt($ch, CURLOPT_USERAGENT, "My user agent"); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $myOtherHeaderStringVariable); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "I want to add data to the request here");
$output = curl_exec($ch);
