What are the potential causes of a Fatal Error when making a SOAP request in PHP?

A Fatal Error when making a SOAP request in PHP can be caused by various issues such as incorrect endpoint URLs, missing required parameters, or server-side errors. To solve this issue, ensure that the endpoint URL is correct, all required parameters are included in the request, and handle any potential server-side errors gracefully.

try {
    $client = new SoapClient("http://example.com/soap.wsdl");
    $response = $client->someFunction(['param1' => 'value1', 'param2' => 'value2']);
    // Process the response
} catch (SoapFault $e) {
    echo "Error: " . $e->getMessage();
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}
