What are common challenges faced when working with SOAP/WSDL in PHP?

One common challenge when working with SOAP/WSDL in PHP is dealing with complex data structures or nested arrays in the SOAP request or response. To solve this, you can use the SoapVar class to create custom SOAP variables with specific data types. 

// Creating a SoapVar object for nested arrays
$nestedArray = array('key1' => 'value1', 'key2' => 'value2');
$soapVar = new SoapVar($nestedArray, SOAP_ENC_ARRAY, 'Array', 'http://www.w3.org/2001/XMLSchema', 'item', array('key1' => 'xsd:string', 'key2' => 'xsd:string'));

// Using the SoapClient to make a SOAP request
$client = new SoapClient("example.wsdl", array('trace' => 1));
$response = $client->__soapCall("exampleMethod", array($soapVar));

// Accessing the SOAP response
var_dump($response);
