I have tried and this is my code
function get_exam_mode_of_study() {
$xml_data = '<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:v1="http://schemas.conversesolutions.com/xsd/dmticta/v1">
<soapenv:Header/>
<soapenv:Body>
<v1:GetOnGoingVehicleNo>
<v1:vehicleCategory>1</v1:vehicleCategory>
</v1:GetOnGoingVehicleNo>
</soapenv:Body>
</soapenv:Envelope>';
$URL = "http://api.lankagate.gov.lk:8280/GetOnGoingVehicleNoDMT/1.0";
$ch = curl_init($URL);
// curl_setopt($ch, CURLOPT_MUTE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml_data");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
print_r($output);
exit;
curl_close($ch);
// }
}
and it gives following error
<ams:fault xmlns:ams="http://wso2.org/apimanager/security"><ams:code>900902</ams:code><ams:message>Missing Credentials</ams:message><ams:description>Required OAuth credentials not provided. Make sure your API invocation call has a header: "Authorization: Bearer ACCESS_TOKEN"</ams:description></ams:fault>

Answer 1

You need to add the Authorization header
CURLOPT_HTTPHEADER for curl_setopt() takes an array with each header as an element.
You can use below $header array.
$header = array();
$header[] = 'Content-length: 0';
$header[] = 'Content-type: application/json';
$header[] = 'Authorization: Bearer OAuthAccess_TokenThatIReceived';
curl_setopt($ch, CURLOPT_HTTPHEADER,$header);
