In the function myimport the author uses 'foo.bar.*' in an attempt to then use JLoader::import to import all files from a directory. However, JLoader does not resolve the wildcard character to list all of the files in the given directory, so it is necessary to individually import each file from the directory. It is possible to work around this problem by designing a separate function to iterate the directories contents and then use JLoader to import them. Agreed, this was deprecated, I don’t think this was ever actually used in the stable releases of 1.5. Here’s a suggested alternative: How do we use the myimport() function? This example demonstrates how we would import the file in mylibrary/foo/bar/baz: JPluginHelper::importPlugin('mylibrary', 'base'); myimport('foo.bar.baz');
