How to properly send and receive XML using curl?
(2 answers)
Closed 9 years ago.
I have fetched data from server using this code, `$server = 'LOCALHOST:9000';
$headers = array(
"Content-type: text/xml"
,"Content-length: ".strlen($requestXML)
,"Connection: close"
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $server);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $requestXML);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$data = curl_exec($ch);
if(curl_errno($ch)){
print curl_error($ch);
echo " something went wrong..... try later";
}else{
echo " request accepted";
print $data;
curl_close($ch);
}`
Now I have to do reverse, how to send the data into server using php? curl method is the only way or is there any other method to do the same. Give me some example.

Sending/Receiving using cURL is the exact same thing. cURL is based on sending data to an given URL and possibly receiving a response. Let's take a simple example of getting a user and sending a user.
Getting a user would be
$data = array(
'user_id' => 1
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.site.com/getUser.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);
getUser.php does nothing more than search for a user and return the data found.
$response would possibly contain data of the user, perhaps just a text-response containing the name. A serialized PHP array, an XML response with a full user profile.. etc.
Inserting/Sending data
$data = array(
'user_name' => 'Joshua',
'user_email' => 'my#email.com'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.site.com/addUser.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);
addUser.php performs some validation of the fields and if validated inserts a user in the database
$response in this case does not contain the userdata (however: it's a possibility), but more likely the $response contains a result. An ok textresponse, a json/xml response or perhaps a '200 OK' header response
It's all basically the same. There is no difference in getting/sending data using cURL. It's all based on sending a request and in most cases do something with the outcome.
