How can the SOAP request be debugged when encountering errors like "Server was unable to read request" in PHP?

When encountering errors like "Server was unable to read request" in PHP when making a SOAP request, it is likely due to an issue with the SOAP request itself. To debug this issue, you can enable error reporting and capture the SOAP request and response for further analysis. This can help identify any formatting or data issues causing the server to be unable to read the request.

// Enable error reporting to help debug SOAP request issues
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Create a SOAP client
$client = new SoapClient("http://example.com/soap.wsdl");

// Capture SOAP request and response for debugging
$soapRequest = $client->__getLastRequest();
$soapResponse = $client->__getLastResponse();

// Output SOAP request and response for analysis
echo "SOAP Request: " . $soapRequest . "\n";
echo "SOAP Response: " . $soapResponse . "\n";
