From: pornel at despammed dot com Operating system: * PHP version: 5.1.0RC1 PHP Bug Type: Feature/Change Request Bug description: late binding for static calls
Description: ------------ In PHP it is not possible to write base class for singleton and similar programming patterns. I know it is intended behavior and backwards compatibility may make changes difficult, but there is significant number of complaints about current implementation: http://bugs.php.net/bug.php?id=30235 http://bugs.php.net/bug.php?id=30934 http://bugs.php.net/bug.php?id=30423 http://bugs.php.net/bug.php?id=19376 http://bugs.php.net/bug.php?id=26930 http://bugs.php.net/bug.php?id=28442 http://bugs.php.net/bug.php?id=29647 and I'd like to add another one. I'm trying to write functionality that works similar to ActiveRow implementation in RubyOnRails, but the way in which PHP handles static methods and inheritance makes such implementation impossible. I hope you could implement late binding for static calls and fields. It could be used with this:: construct instead of self::, which may be emulated for backwards compatiblity. Reproduce code: --------------- class Base { static function test1() {self::test2();} static function test2() {echo 'failure';} } class Child { static function test2() {echo 'success';} } Child::test(); Expected result: ---------------- success Actual result: -------------- failure backtrace doesn't contain reference to Child class (that would be enough for a workaround). -- Edit bug report at http://bugs.php.net/?id=34703&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34703&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34703&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34703&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34703&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34703&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34703&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34703&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34703&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34703&r=support Expected behavior: http://bugs.php.net/fix.php?id=34703&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34703&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34703&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34703&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34703&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34703&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34703&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34703&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34703&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34703&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34703&r=mysqlcfg
