From: matthew_kay at ml1 dot net Operating system: Linux 2.4.22 (Mandrake 9.2) PHP version: 5.0.0RC1 PHP Bug Type: Zend Engine 2 problem Bug description: Cannot serialize/unserialize non-finite numeric values
Description: ------------ It appears that unserialize() does not unserialize numerics that are "non-finite", such as NAN and INF. Instead, it simply fails and returns (bool)false. If a NAN value is encountered anywhere during an unserialize() (for example, in an array or an object), the entire operation fails and unserialize will return false. Reproduce code: --------------- $testNan = (float)NAN; var_dump($testNan); //outputs float(NAN) $testNan2 = unserialize(serialize($testNan)); var_dump($testNan2); //outputs bool(false) $testInf = (float)INF; var_dump($testInf); //outputs float(INF) $testInf2 = unserialize(serialize($testInf)); var_dump($testInf2); //outputs bool(false) Expected result: ---------------- float(NAN) float(NAN) float(INF) float(INF) Actual result: -------------- float(NAN) bool(false) float(INF) bool(false) -- Edit bug report at http://bugs.php.net/?id=27646&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27646&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27646&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27646&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27646&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27646&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27646&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27646&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27646&r=support Expected behavior: http://bugs.php.net/fix.php?id=27646&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27646&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27646&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27646&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27646&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27646&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27646&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27646&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27646&r=float
