#41214 [NEW]: referencing a reference parameter on a function-local variable does not work

From: php at warhog dot net Operating system: Linux (Ubuntu 6.10/Linux 2.6.17) PHP version: 5.2.1 PHP Bug Type: Variables related Bug description: referencing a reference parameter on a function-local variable does not work Description: ------------ When having a reference-variable as parameter in a function and referencing it on a local variable (inside the function) the variable will keep the referenced value inside the function but not outside. That's not the way I understand references in PHP. Reproduce code: --------------- <?php function yet_another_function(&$foo) { $_foo = 3; $foo =& $_foo; var_dump($foo); } yet_another_function($bar); var_dump($bar); ?> Expected result: ---------------- int(3) int(3) Actual result: -------------- int(3) NULL -- Edit bug report at http://bugs.php.net/?id=41214&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41214&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41214&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41214&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41214&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41214&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41214&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41214&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41214&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41214&r=support Expected behavior: http://bugs.php.net/fix.php?id=41214&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41214&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41214&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41214&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41214&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41214&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41214&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41214&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41214&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41214&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41214&r=mysqlcfg
