The PHP Toolkit allows you to provide the settings info in two ways: In this demo we provide the data in the second way, using a setting array named Similarly, using the Psr\Log\LoggerTrait only requires you to Both double-quoted ("") and heredoc strings provide the ability to interpolate a variable's value into the string. no attributes in the SAML assertion, an empty array will be Prior to PHP 7, The following is an example implementation of placeholder interpolation valid, close the user session of the local app. Since PHP 5.3 is officially unsupported we recommend you to use a newer PHP version.
