From: Marcel dot Glacki at stud dot fh-swf dot de Operating system: any PHP version: 5.2.9 PHP Bug Type: Arrays related Bug description: Generated index is reset due to integer overflow
Description: ------------ The generated index normally has the highest integer value regarding all integers it has encountered as indexes before. (And is automatically increased by +1) It is possible to reset this index (the internal pointer) not only by the functions intended to do so (like reset()) but also by increasing it above integers' max value (integer overflow). Reproduce code: --------------- <?php $max_int = 2147483647; // Max value for integer on a 32-bit system $arr = array(); $arr[1] = 'one'; // New index: 2 $arr[ $max_int ] = 'two'; // New index: -2147483648 $arr[0] = 'three'; // New index: 1 (already occupied with value 'foo') $arr[] = 'failure here'; // Warning: Cannot add element to the array as the next element is already occupied. ?> -- Edit bug report at http://bugs.php.net/?id=48093&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48093&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48093&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48093&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48093&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48093&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48093&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48093&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48093&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48093&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48093&r=support Expected behavior: http://bugs.php.net/fix.php?id=48093&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48093&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48093&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48093&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48093&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48093&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48093&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48093&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48093&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48093&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48093&r=mysqlcfg
