If it isn't already obvious, you can create an object of a class above the class declaration if it does NOT implement an interface. However, when a class DOES implement an interface, PHP will throw a "class not found" error unless the instantiation declaration is _below_ the class definition. <?php $bar = new foo(); // Valid class foo { } ?> <?php $bar = new foo(); // Invalid - throws fatal error interface foo2 { } class bar implements foo2 { } $bar = new foo(); // Valid, since it is below the class declaration ?> Also, @Jeffrey -- Lol? What? Is that a joke? PHP interfaces have nothing to do with connecting to "peripheral devices" or "cameras", etc. Not even in the least sense. This is a very common miscommunication with the word "interface", as interfaces in programming are not at all like interfaces in electronics or drivers, etc. ---- Server IP: 69.147.83.197 Probable Submitter: 70.56.151.147 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.interfaces.php Edit -- https://master.php.net/note/edit/101723 Del: integrated -- https://master.php.net/note/delete/101723/integrated Del: useless -- https://master.php.net/note/delete/101723/useless Del: bad code -- https://master.php.net/note/delete/101723/bad+code Del: spam -- https://master.php.net/note/delete/101723/spam Del: non-english -- https://master.php.net/note/delete/101723/non-english Del: in docs -- https://master.php.net/note/delete/101723/in+docs Del: other reasons-- https://master.php.net/note/delete/101723 Reject -- https://master.php.net/note/reject/101723 Search -- https://master.php.net/manage/user-notes.php
