note 54550 added to language.oop5.patterns

Please use design patterns as they were intended: Design patterns are designs that are known to solve common problems, such as having only 1 instance of a class. Design patterns are are not code libraries. Most design patterns, if not all, have alternate implementations but common to them all is that the recommended implementation solves the problem. Singleton should not be made as a class and then extended. Nor shuld __autoload be used. Autoloading is very PHP-specific (and there might be nothing wrong with that, but design patterns are general patterns that are abstracted from the implementing language). Making a class that you extend is very ugly. What if you have to extend that class too? You will have to make a dummy that extends your singleton class, just so you can extend the class you want. This is a very "ugly" solution that completely overrules the idea of well known design patters: A thought-though idea that works the way intended. The manual shows a PHP implementation of the standard Singleton-pattern without "nifty" modifications. To finish off this lesson on design patterns, I would like to ackknowledge that there is nothing wrong in tweaking patterns to suit your needs. But remember: "If it isn't broken - don't fix it". ---- Manual Page -- http://www.php.net/manual/en/language.oop5.patterns.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54550 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54550&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54550&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54550&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54550&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54550&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54550&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54550&report=yes Search -- http://master.php.net/manage/user-notes.php
