#33537 [NEW]: assignment of $this to another var

From: bo at theaddedones dot com Operating system: OS X PHP version: 5CVS-2005-07-01 (dev) PHP Bug Type: Class/Object related Bug description: assignment of $this to another var Description: ------------ i can understand this error from inside a class class Foo{ function bar(){ $this =& $something_else; } } but i should think one can assign a ref to $this to another var. class Foo{ function bar(){ $this_dupe =& $this; //fails to compile $this_dupe = $this; //compiles okay } } the reason i bring this up, is in php4 and 5.0 this is allowed .. if code needs to run on php4 without silly performance hits (i.e. data copy on assignment), would be nice to keep that. from the error it seems it is trying to do this $this =& $this_dupe .. but that is not what is being done Reproduce code: --------------- <?php class Foo{ function bar(){ $this_dupe =& $this; //fails to compile $this_dupe = $this; //works a okay } } Expected result: ---------------- hopefully it should compile fine Actual result: -------------- Fatal error: Cannot re-assign $this in {test.php} on line 4 -- Edit bug report at http://bugs.php.net/?id=33537&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33537&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33537&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33537&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33537&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33537&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33537&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33537&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33537&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33537&r=support Expected behavior: http://bugs.php.net/fix.php?id=33537&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33537&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33537&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33537&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33537&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33537&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33537&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33537&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33537&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33537&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33537&r=mysqlcfg
