#47836 [NEW]: array operator [] has inconsistency when the array has PHP_MAX_INT index value.

From: for-bugs at hnw dot jp Operating system: * PHP version: 5.2.9 PHP Bug Type: Arrays related Bug description: array operator [] has inconsistency when the array has PHP_MAX_INT index value. Description: ------------ The behavior of operator [] to the array is sometimes strange or hard to describe the specification. For instance, the array which has two index, 2147483647 and -2147483648 on 32bit environment gets strange results. See below example: Reproduce code: --------------- <?php $array=array(); $array[-2147483648]=2; $array[2147483647]=1; $array[]=3; var_dump($array); $array=array(); $array[2147483647]=1; $array[-2147483648]=2; $array[]=3; var_dump($array); Expected result: ---------------- It should be same behavior. I think, the substitution to $array[] shuold be both failed for this case. Actual result: -------------- PHP Warning: Cannot add element to the array as the next element is already occupied in ./array-maxint-test.php on line 5 array(2) { [-2147483648]=> int(2) [2147483647]=> int(1) } array(3) { [2147483647]=> int(1) [-2147483648]=> int(2) [-2147483647]=> int(3) } -- Edit bug report at http://bugs.php.net/?id=47836&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47836&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47836&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47836&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47836&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47836&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47836&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47836&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47836&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47836&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47836&r=support Expected behavior: http://bugs.php.net/fix.php?id=47836&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47836&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47836&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47836&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47836&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47836&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47836&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47836&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47836&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47836&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47836&r=mysqlcfg
