Three more that we discovered: == 1. No longer can re-assign $this == The follwoing example works under PHP4 (it outputs "OK"), but produces a fatal error under PHP5: <? class a { var $text; function a() { $this->text = 'OK'; } } class b { var $text = 'NOT OK'; function b() { $this = new a(); } } $myClass = new b(); echo $myClass->text; ?> == 2. No comments allowed after shorthand echo block == The follwoing example works under PHP4, but produces a sytax error under PHP5. <?=//comment?> == 3. Constructors return a reference as default == The follwoing example works under PHP4, but produces an E_NOTICE notice under PHP5. <? class MyClass { function MyClass() { echo('OK'); } } $myObj = null; $myObj &= new MyClass(); ?> Removing the ampersand solves the problem ---- Server IP: 203.16.234.19 Probable Submitter: 128.184.132.11 (proxied: 128.184.148.54) ---- Manual Page -- http://www.php.net/manual/en/migration5.incompatible.php Edit -- https://master.php.net/note/edit/81932 Del: integrated -- https://master.php.net/note/delete/81932/integrated Del: useless -- https://master.php.net/note/delete/81932/useless Del: bad code -- https://master.php.net/note/delete/81932/bad+code Del: spam -- https://master.php.net/note/delete/81932/spam Del: non-english -- https://master.php.net/note/delete/81932/non-english Del: in docs -- https://master.php.net/note/delete/81932/in+docs Del: other reasons-- https://master.php.net/note/delete/81932 Reject -- https://master.php.net/note/reject/81932 Search -- https://master.php.net/manage/user-notes.php
