SOAP authentication with PHP

Question

I need to connect to a web service that requires authentication credentials in the form of a plain text user name and password.

I have a basic understanding of SOAP

Answer 1

If you have the SOAP extension enabled in php (php version >= 5.0.1), you can use the SoapClient class to process your request. To authenticate, you can pass the username and password to the class with the target URL:

$soapURL = "https://www.example.com/soapapi.asmx?wsdl" ;
$soapParameters = Array('login' => "myusername", 'password' => "mypassword") ;
$soapFunction = "someFunction" ;
$soapFunctionParameters = Array('param1' => 42, 'param2' => "Search") ;

$soapClient = new SoapClient($soapURL, $soapParameters);

$soapResult = $soapClient->__soapCall($soapFunction, $soapFunctionParameters) ;

if(is_array($soapResult) && isset($soapResult['someFunctionResult'])) {
    // Process result.
} else {
    // Unexpected result
    if(function_exists("debug_message")) {
        debug_message("Unexpected soapResult for {$soapFunction}: ".print_r($soapResult, TRUE)) ;
    }
}

If you're not sure about the functions you can call, you can view the target URL (e.g. ending in ".asmx?wsdl") in your browser. You should get an XML response that tells you the available SOAP functions you can call, and the expected parameters of those functions.
