If you create an array with large integers as the keys, serialize the array, and unserialize the array, (so you can pass it through a session) the array key value is not being type promoted to a data type that can store the large integer. Instead you get a different value back as the key after unserializing the array. This is happening with the 64 bit versions of 5.0.3 and 4.3.2. Reproduce code: --------------- $array["1234567891011"] = 'test'; print "The array:<br/>"; var_dump( $array); $array_serialized = serialize($array); $array_unserialized = unserialize($array_serialized); print "<br/>The unserialized array:<br/>"; var_dump($array_unserialized); Expected result: ---------------- The array: array(1) { [1234567891011]=> string(4) "test" } The unserialized array: array(1) { [1234567891011]=> string(4) "test" } *Note: this is what you get back in the 32 bit version of php. Actual result: -------------- The array: array(1) { [1234567891011]=> string(4) "test" } The unserialized array: array(1) { [1912277059]=> string(4) "test" } *Note: this is what you get back in the 64 bit version of php. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32213&edit=1
