#39337 [NEW]: Array creation when using overloading (__get) does not work (NULL)

From: phpbugs at thequod dot de Operating system: Ubuntu Linux PHP version: 5CVS-2006-11-01 (CVS) PHP Bug Type: Arrays related Bug description: Array creation when using overloading (__get) does not work (NULL) Description: ------------ Creating an array through $obj->a[] or $obj->a[$index] does not create an array, if you use overloading through the "__get()" method. This happens with PHP_5_2 and 5.1.6 from Ubuntu, which I've also tested. The workaround seems to be to initialize the member explicitly to "array()". Reproduce code: --------------- <?php class A { function __get($v) { // note: even returning array() here won't fix it } } $A = new A(); $A->foo[1] = 1; var_dump( $A->foo ); $A->foo[] = 2; var_dump( $A->foo ); $A->foo['a'] = 3; var_dump( $A->foo ); $A->foo = array(); var_dump( $A->foo ); $A->foo = 1; var_dump( $A->foo ); ?> Expected result: ---------------- array(1) { [1]=> int(1) } array(2) { [1]=> int(1) [2]=> int(2) } array(3) { [1]=> int(1) [2]=> int(2) ["a"]=> int(3) } array(0) { } int(1) Actual result: -------------- NULL NULL NULL array(0) { } int(1) -- Edit bug report at http://bugs.php.net/?id=39337&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39337&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39337&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39337&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39337&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39337&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39337&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39337&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39337&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39337&r=support Expected behavior: http://bugs.php.net/fix.php?id=39337&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39337&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39337&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39337&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39337&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39337&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39337&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39337&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39337&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39337&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39337&r=mysqlcfg
