From: stochnagara at hotmail dot com Operating system: windows xp PHP version: 5.0.4 PHP Bug Type: Class/Object related Bug description: Wrong private method virtual behaviour Description: ------------ When a private method is overriden and the visibility is increased to public or protected, then this method loses its non-virtual behaviour in methods of classes where the method is private. So in the example bellow ext2::abc is called instead of base::abc and ext::abc. Also when the function prototype is different warning appear. Reproduce code: --------------- class base { public function test() { $this->abc(); } public function test2() { $this->abc(); } private function abc() { echo "base::abc<br/>"; } } class ext extends base { public function test2() { $this->abc(null); } private function abc ($param1) { echo "ext::abc<br/>"; } } class ext2 extends ext { protected function abc ($param1, $param2) { echo "ext2::abc<br/>"; } } $base = new base(); $base->test(); $base->test2(); $ext = new ext(); $ext->test(); $ext->test2(); $ext2 = new ext2(); $ext2->test(); $ext2->test2(); Expected result: ---------------- base::abc base::abc base::abc ext::abc base::abc ext::abc Actual result: -------------- base::abc base::abc base::abc ext::abc Warning: Missing argument 1 for ext2::abc() in c:\program files\apache group\Apache\htdocs\php5\pproject4\test.php on line 12 Warning: Missing argument 2 for ext2::abc() in c:\program files\apache group\Apache\htdocs\php5\pproject4\test.php on line 12 ext2::abc Warning: Missing argument 2 for ext2::abc() in c:\program files\apache group\Apache\htdocs\php5\pproject4\test.php on line 12 ext2::abc -- Edit bug report at http://bugs.php.net/?id=34018&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34018&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34018&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34018&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34018&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34018&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34018&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34018&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34018&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34018&r=support Expected behavior: http://bugs.php.net/fix.php?id=34018&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34018&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34018&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34018&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34018&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34018&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34018&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34018&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34018&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34018&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34018&r=mysqlcfg
