note 80151 added to language.oop5.patterns

For anyone who reads: me at chrisstockton dot org The note being refered to by that post is actually correct. A singleton provides essentially the same functionality as a global variable refering to an object combined with code to create the object at first use or application initialization. Using them is just a much more involved and difficult to follow technique involving class instantiation. Although perhaps appropriate in some circumstances, for many uses the global variable approach makes more sense. The note being refered to is also correct regarding design patterns. Using design patterns and using interfaces should not be confused, they are nothing the same. Authors of 'pay-for software' (those 'large scale enterprise applications') have to get our laughs some way or another! One final point neither note writer seems to get. PHP 5 accommodates many architectures, and is quite valuable for building scalable applications, even though it is still (thank God) free. PHP is now one of the 'big guys', and it needs these object oriented capabilities, even though they might be confusing to some. ---- Server IP: 209.41.74.194 Probable Submitter: 66.214.49.84 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.patterns.php Edit -- https://master.php.net/note/edit/80151 Del: integrated -- https://master.php.net/note/delete/80151/integrated Del: useless -- https://master.php.net/note/delete/80151/useless Del: bad code -- https://master.php.net/note/delete/80151/bad+code Del: spam -- https://master.php.net/note/delete/80151/spam Del: non-english -- https://master.php.net/note/delete/80151/non-english Del: in docs -- https://master.php.net/note/delete/80151/in+docs Del: other reasons-- https://master.php.net/note/delete/80151 Reject -- https://master.php.net/note/reject/80151 Search -- https://master.php.net/manage/user-notes.php
