#44043 [NEW]: Enforcing a method without specifying the arguments

From: j dot boggiano at seld dot be Operating system: Windows/Linux PHP version: 6CVS-2008-02-04 (snap) PHP Bug Type: Class/Object related Bug description: Enforcing a method without specifying the arguments Description: ------------ The purpose of this is to allow an abstract class or an interface to enforce the implementation of a method, without however enforcing the arguments signature. This is -as I understand it- not a bug, but a feature request. Reproduce code: --------------- /*** * This works in PHP5 but does not anymore in PHP6 */ class Parnt { public function foo() {} } class Child extends Parnt { public function foo($arg){} } /*** * Those don't work in either 5 or 6 */ abstract class Abst { abstract public function foo(); } class Child2 extends Abst { public function foo($arg){} } interface Int { public function foo(); } class Child3 implements Int { public function foo($arg){} } Expected result: ---------------- /*** * Proposal for a solution */ abstract class AbstFixed { abstract public function foo; } class Child4 extends AbstFixed { public function foo($arg){} } // => Declaring the method without parenthesis (which currently throws a parse error) would allow the implementations of this method to use any argument signature they please. Actual result: -------------- At the moment those three examples throw a fatal error in PHP6 with : Declaration of Child::foo() must be compatible with that of Parnt::foo() I don't think it is a bug, but I think having the capability to allow variable function signatures would definitely be a plus, especially with PHP6 coming that prevents the first example to work. -- Edit bug report at http://bugs.php.net/?id=44043&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=44043&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44043&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44043&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44043&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44043&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44043&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44043&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44043&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44043&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44043&r=support Expected behavior: http://bugs.php.net/fix.php?id=44043&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44043&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44043&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44043&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=44043&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=44043&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44043&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44043&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44043&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44043&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44043&r=mysqlcfg
