#26921 [NEW]: Redefined property in child class modified out of context in parent class

From: jamie at sailor dot org dot uk Operating system: Win2K PHP version: 4.3.4 PHP Bug Type: Class/Object related Bug description: Redefined property in child class modified out of context in parent class Description: ------------ I define variable A within parent class cFoo, and initialise it within the class Constructor. I redefine variable A within child class cBar, and initialise it within the class Constructor which then calls the parent class Constructor. The parent constructor modifies the child instance of property A rather than the parent instance. Reproduce code: --------------- <?php /* Inheritance test2. Inherited Vars */ class cFoo { var $A; function cFoo() /* constructor */ { $this->A = "cFoo_A"; } function Display() { print("Within cFoo::Display; property A = '$this->A'; should be 'cFoo_A'<br>\n"); } }; class cBar extends cFoo { var $A; // redefines A function cBar() /* constructor */ { $this->A = "cBar_A"; $this->cFoo(); /* parent constructor */ } function Display() { print("Within cBar::Display; property A = '$this->A'; should be 'cBar_A'<br>\n"); } }; $foo1 = new cFoo; $foo1->Display(); $bar1 = new cBar; $bar1->Display(); exit; ?> Expected result: ---------------- Within cFoo::Display; property A = 'cFoo_A'; should be 'cFoo_A' Within cBar::Display; property A = 'cBar_A'; should be 'cBar_A' Actual result: -------------- Within cFoo::Display; property A = 'cFoo_A'; should be 'cFoo_A' Within cBar::Display; property A = 'cFoo_A'; should be 'cBar_A' -- Edit bug report at http://bugs.php.net/?id=26921&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=26921&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=26921&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=26921&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=26921&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=26921&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=26921&r=needscript Try newer version: http://bugs.php.net/fix.php?id=26921&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=26921&r=support Expected behavior: http://bugs.php.net/fix.php?id=26921&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=26921&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=26921&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=26921&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=26921&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=26921&r=dst IIS Stability: http://bugs.php.net/fix.php?id=26921&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=26921&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=26921&r=float
