How can PHP version compatibility, such as using PHP 5.3, affect the functionality of SoapClient requests and timeouts?

When using an older PHP version like 5.3, it may not support some of the newer features and functions required by SoapClient requests. This can lead to compatibility issues and potential timeouts due to the inability to establish a connection or process the request properly. To solve this issue, it is recommended to upgrade to a newer PHP version that supports the required features for SoapClient requests.

// Example of setting a timeout for SoapClient requests in PHP 5.3
$soapClient = new SoapClient("http://example.com/soap.wsdl", array('connection_timeout' => 10, 'timeout' => 10));
