Cake PHP - Controller action visibility

You can also change the visibility of controller methods in CakePHP by prefixing controller method names with underscores. If a controller method has been prefixed with an underscore, the method will not be accessible directly from the web but is available for internal use. For example:

<?php
class NewsController extends AppController {
 
	function latest() {
		$this->_findNewArticles();
	}
	
	function _findNewArticles() {
		//Logic to find latest news articles
	}
}

?>

1. <?php
2. class NewsController extends AppController {
3. function latest() {
4. $this->_findNewArticles();
5. }
7. function _findNewArticles() {
8. //Logic to find latest news articles
9. }
10. }
11. ?>

While the page http://www.example.com/news/latest/ would be accessible to the user as usual, someone trying to get to the page http://www.example.com/news/_findNewArticles/ would get an error, because the method is preceded with an underscore.
