Php code to execute payment using xml api

$result = makeCurlCall(
    $testNab, /* CURL URL */
    "POST", /* CURL CALL METHOD */
    array( /* CURL HEADERS */
        "Content-Type: text/xml; charset=utf-8",
        "Accept: text/xml",
        "Pragma: no-cache",
        "Content_length: ".strlen(trim($nabXml))
    ),
    null, /* CURL GET PARAMETERS */
    $nabXml /* CURL POST PARAMETERS AS XML */
);

makeCurlCall function

function makeCurlCall($url, $method = "GET", $headers = null, $gets = null, $posts = null) {
    $ch = curl_init();
    if($gets != null)
    {
        $url.="?".(http_build_query($gets));
    }
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    if($posts != null)
    {
        curl_setopt($ch, CURLOPT_POSTFIELDS, $posts);
    }
    if($method == "POST") {
        curl_setopt($ch, CURLOPT_POST, true);
    } else if($method == "PUT") {
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
    } else if($method == "HEAD") {
        curl_setopt($ch, CURLOPT_NOBODY, true);
    }
    if($headers != null && is_array($headers))
    {
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    }
    $response = curl_exec($ch);
    $code = curl_getinfo($ch,CURLINFO_HTTP_CODE);

    curl_close($ch);
