note 62575 added to language.oop5.patterns

I don't get the point of using the Singleton pattern in PHP. I have created and ran these example (class Example "Example.php" and the test page "examplepage.php"). I've commented out the lines that would issue errors (new Example & clone). When I call and reload examplepage.php in the browser, I *always* get the same response: "I am constructed Woof!", which means it's *always* creating a new instance of class Example. I expected that, starting from the second call to the page (reload), the response would be just "Woof". Am I doing something wrong? ---- Server IP: 66.163.161.117 Probable Submitter: 200.199.23.121 (proxied: 172.27.139.229, 172.27.139.1) ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.patterns.php Edit -- http://master.php.net/note/edit/62575 Del: integrated -- http://master.php.net/note/delete/62575/integrated Del: useless -- http://master.php.net/note/delete/62575/useless Del: bad code -- http://master.php.net/note/delete/62575/bad+code Del: spam -- http://master.php.net/note/delete/62575/spam Del: non-english -- http://master.php.net/note/delete/62575/non-english Del: in docs -- http://master.php.net/note/delete/62575/in+docs Del: other reasons-- http://master.php.net/note/delete/62575 Reject -- http://master.php.net/note/reject/62575 Search -- http://master.php.net/manage/user-notes.php
