setting extra variables to Curl connection string - php

Question

I am using php/curl to make a connection to an external api. It is working fine but right now my connection string only references one variable from a form.
How can I make it references more than one?
This is how it looks like now
$curl_connection =curl_init('https://api.ssllabs.com/api/v2/analyze?host='.$_REQUEST['host']);
When making a call the above will look like this:
https://api.ssllabs.com/api/v2/analyze?host=www.yourdomain.com
My form has been updated and contains more input values which I want to reference as part of the curl connection and needs to look like this:
https://api.ssllabs.com/api/v2/analyze?host=www.yourdomain.com&s=69.54.183.66&ignoreMismatch=on
Each reference is seperated by the & symbol.
On my html form the input names are as follows:
host
s
ignoreMismatch
There are others aswell.. but the above is a sample
I hope that's clear enough for your to know what I am trying to do.
Here is a portion of my jquery / Ajax
var hostName = $("input#host").val();
var ignoreMismatch = $("#ignoreMismatch").val();
var fromCache = $("#fromCache").val();
dataString = "host=" + hostName + "&fromCache=" + fromCache + "&ignoreMismatch=" + ignoreMismatch;
enter code here
$.ajax({
type: "GET",
url: "api2.php",
data: dataString,
dataType: "json",
I can see this part is working. From my web console I can see the URL is built and posted to the api2.php file.
For example https://172.21.121.37/labs/api2.php?host=ocsp.verisign.com&fromCache=on&ignoreMismatch=on
Here is my api2.php file which is currently only setup to receive host= string.
<?php
header( "Content-Type: application/json" );
//create cURL connection
$curl_connection =curl_init('https://api.ssllabs.com/api/v2/analyze?host='.$_REQUEST['host']);
///set options
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);
//perform our request
$result = curl_exec($curl_connection);
echo $result;
//close the connection
curl_close($curl_connection);
?>
This is working code by the way but I just wanted to give you guys more context as I tried some of the suggestions provided and they didn't work. If someone can help update my api2.php file I will test the updates.

This should help you
foreach($_GET as $name => $value) {
$encoded .= urlencode($name).'='.urlencode($value).'&';
}
$encoded = substr($encoded, 0, strlen($encoded)-1);
$ch = curl_init("https://api.ssllabs.com/api/v2/analyze?" . $encoded);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
