From: eric dot daspet at survol dot net Operating system: MS Windows XP PHP version: 5.1.4 PHP Bug Type: SPL related Bug description: first call to unset() fails with ArrayObjet on a multidimensionnal superglobal Description: ------------ When a multidimentional superglobal is used to feed ArrayObjet, the first unset of a sub-index is ignored. - it is ok with a "normal" array, I've seen this only with $_REQUEST and $_GET - it is ok with $_GET as a simple array (one dimension) - the second call to unset() succeed, either if is the exact same call or if I try to unset another index, only the first fails Reproduce code: --------------- <?php // call the script with ?index[i]=1&index[j]=2 $ao = new ArrayObject( $_GET ) ; unset( $ao['index']['i'] ) ; // ignored var_dump($ao) ; unset( $ao['index']['j'] ) ; // ok var_dump($ao) ; unset( $ao['index']['i'] ) ; // ok var_dump($ao) ; Expected result: ---------------- object(ArrayObject)#1 (1) { ["index"]=> array(2) { ["i"]=> string(1) "1" ["j"]=> string(1) "2" } } object(ArrayObject)#1 (1) { ["index"]=> array(1) { ["i"]=> string(1) "1" } } object(ArrayObject)#1 (1) { ["index"]=> array(0) { } } Actual result: -------------- object(ArrayObject)#1 (1) { ["index"]=> array(1) { ["j"]=> string(1) "1" } } object(ArrayObject)#1 (1) { ["index"]=> array(0) { } } object(ArrayObject)#1 (1) { ["index"]=> array(0) { } } -- Edit bug report at http://bugs.php.net/?id=37742&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37742&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37742&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37742&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37742&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37742&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37742&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37742&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37742&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37742&r=support Expected behavior: http://bugs.php.net/fix.php?id=37742&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37742&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37742&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37742&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37742&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37742&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37742&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37742&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37742&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37742&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37742&r=mysqlcfg
