#44181 [NEW]: extract($a, EXTR_OVERWRITE|EXTR_REFS) can fail to create references to $a

From: robin_fernandes at uk dot ibm dot com Operating system: Windows PHP version: 5.2CVS-2008-02-20 (snap) PHP Bug Type: Arrays related Bug description: extract($a, EXTR_OVERWRITE|EXTR_REFS) can fail to create references to $a Description: ------------ Using extract() with EXTR_OVERWRITE|EXTR_REFS does not create references to the array elements if the following conditions are true: - $a is referenced by some other variable (its is_ref flag is true). - A variable already exists in the current scope with a name matching the key. This is reproducible on 5.2, 5.3 and 6.0 snaps. Reproduce code: --------------- <?php $a = array('foo' => 'original.foo'); $foo = 'test'; $ref = &$a; extract($a, EXTR_OVERWRITE|EXTR_REFS); $foo = 'changed.foo'; var_dump($a['foo']); //expecting changed.foo ?> Expected result: ---------------- string(11) "changed.foo" Actual result: -------------- string(12) "original.foo" -- Edit bug report at http://bugs.php.net/?id=44181&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44181&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44181&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44181&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44181&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44181&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44181&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44181&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44181&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44181&r=support Expected behavior: http://bugs.php.net/fix.php?id=44181&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44181&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44181&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44181&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44181&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44181&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44181&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44181&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44181&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44181&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44181&r=mysqlcfg
