From: Operating system: Linux Ubuntu 10.04 PHP version: 5.3.2 Package: Scripting Engine problem Bug Type: Bug Bug description:Functions cannot return an argument passed by reference as reference
Description: ------------ PHP does not behave as expected when passing arguments by reference into a function that are passed out again by reference. IMO, the below test script should behave equivalently to the following code (which produces the expected result): $b = 'foobar'; $a =& $b; $c =& $a; $c[2] = 'z'; var_dump($c); var_dump($b); Test script: --------------- function &ref(&$a) { return $a; } $b = 'foobar'; $c = ref($b); $c[2] = 'z'; Expected result: ---------------- string 'fozbar' (length=6) string 'fozbar' (length=6) Actual result: -------------- string 'fozbar' (length=6) string 'foobar' (length=6) -- Edit bug report at http://bugs.php.net/bug.php?id=52133&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52133&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52133&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52133&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52133&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52133&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52133&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52133&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52133&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52133&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52133&r=support Expected behavior: http://bugs.php.net/fix.php?id=52133&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52133&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52133&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52133&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52133&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52133&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52133&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52133&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52133&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52133&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52133&r=mysqlcfg
