SOAP request in PHP with CURL

Php code to soap action via curl:

<?php
$xml = '<?xml version="1.0" encoding="utf-8"?>'.
    '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"'.
    ' xmlns:xsd="http://www.w3.org/2001/XMLSchema"'.
    ' xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'.
        '<soap:Body>'.
            '<GetShirtInfo xmlns="http://api.soap.website.com/WSDL_SERVICE/">'.
                '<ItemId>15</ItemId>'.
            '</GetShirtInfo>'.
        '</soap:Body>'.
    '</soap:Envelope>';

$url = "https://api.soap.website.com/soap.asmx?wsdl";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

$headers = array();
array_push($headers, "Content-Type: text/xml; charset=utf-8");
array_push($headers, "Accept: text/xml");
array_push($headers, "Cache-Control: no-cache");
array_push($headers, "Pragma: no-cache");
array_push($headers, "SOAPAction: http://api.soap.website.com/WSDL_SERVICE/GetShirtInfo");
if($xml != null) {
    curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml");
    array_push($headers, "Content-Length: " . strlen($xml));
}
curl_setopt($ch, CURLOPT_USERPWD, "user_name:password"); /* If required */
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
?>

And output would be like this:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <ShirtInfoResponse
            xmlns="http://api.soap.website.com/WSDL_SERVICE/">
            <ShirtInfo>
                <ItemId>15</ItemId>
                <ItemName>Some Item Name</ItemName>
                <ItemPrice>658.7</ItemPrice>
                <ItemCurrency>AUD</ItemCurrency>
            </ShirtInfo>
        </ShirtInfoResponse>
    </soap:Body>
</soap:Envelope>
