#39488 [NEW]: unserialize does not convert array keys to proper type

From: michaelw at darkhorse dot com Operating system: os x PHP version: 5.2.0 PHP Bug Type: *General Issues Bug description: unserialize does not convert array keys to proper type Description: ------------ When dealing with an incorrectly formatted serialized array (such as from a source other than PHP like a javascript, or hand-coded), unserialize() does not check and convert array keys that are stored as strings but should be integers. This makes it impossible to recover the value through any sort of type-casting. Reproduce code: --------------- $badly_serialized_array = 'a:1:{s:1:"0";s:1:"a";}'; $back_to_an_array = unserialize($badly_serialized_array); echo $back_to_an_array[0]; echo $back_to_an_array['0']; $v = (string)'0'; echo $back_to_an_array[$v]; Expected result: ---------------- a a a Actual result: -------------- nothing nothing nothing -- Edit bug report at http://bugs.php.net/?id=39488&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39488&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39488&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39488&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39488&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39488&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39488&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39488&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39488&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39488&r=support Expected behavior: http://bugs.php.net/fix.php?id=39488&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39488&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39488&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39488&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39488&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39488&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39488&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39488&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39488&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39488&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39488&r=mysqlcfg
