CURL using GET method instead of POST - php

Question

I have a data submission system that post values via curl to a url like this:
$URL="http://some_url/";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$URL);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_HTTPHEADER, array ('Content-Type:application/x-www-form-urlencoded;application/xml'));
curl_setopt($ch, CURLOPT_POSTFIELDS, "First Name=".$firstname."&Last Name=".$lastname."&Daytime Phone=".$dayphone."&Evening Phone=".$evephone."&DeliveryCode=".$deliveryCode."&username=".$username."&password=".$password);
echo curl_exec ($ch);
curl_close ($ch);
When i inspect the network console, it shows that a GET request was performed instead of POST as desired. What can be the issue.

I don't know why your code does not work, but I give you a code that does work; It may not be the solution, but it will help you to understand cUrl;
Adapt the code as you need it;
