 | |
|  * We have already parsed the server path into App::$argc and App::$argv
 | |
|  *
 | |
|  * App::$argv[0] is our module name. Let's call it 'foo'. We will load the
 | |
|  * Zotlabs/Module/Foo.php (object) or file mod/foo.php (procedural)
 | |
|  * and use it for handling our URL request to 'https://ourgreatwebsite.something/foo' .
 | |
|  * The module file contains a few functions that we call in various circumstances
 | |
|  * and in the following order:
 | |
|  * @code{.php}
 | |
|  * Object:
 | |
|  *    class Foo extends \Zotlabs\Web\Controller {
 | |
|  *        function init() { init function }
 | |
|  *        function post() { post function }
 | |
|  *        function get()  { normal page function }
 | |
|  *    }
 | |
|  *
 | |
|  * Procedual interface:
 | |
|  *        foo_init()
 | |
|  *        foo_post() (only called if there are $_POST variables)
 | |
|  *        foo_content() - the string return of this function contains our page body
 | |
|  * @endcode
 | |
|  * Modules which emit other serialisations besides HTML (XML,JSON, etc.) should do
 | |
|  * so within the module init and/or post functions and then invoke killme() to terminate
 | |
|  * further processing.
