// In this example, we are getting the base URL of the current application and storing it in a variable $baseUrl = getBaseUrl(); echo "The base URL of this application is: $baseUrl"; // Output: The base URL of this application is: http://example.com/
// In this example, we are getting the base URL of a different application and storing it in a variable $baseUrl = getBaseUrl('http://example.com/path/to/app/'); echo "The base URL of the application is: $baseUrl"; // Output: The base URL of the application is: http://example.com/path/to/app/This example uses the getBaseUrl function with an argument, which returns the base URL of the application with the specified URI.
