#32536 [Csd]: Unserialize() and booleans

ID: 32536 User updated by: AxelLuttgens at swing dot be Reported By: AxelLuttgens at swing dot be Status: Closed Bug Type: Documentation problem Operating System: n/a PHP Version: 4.3.10 New Comment: And many thanks to both of you, vrana and didou! Axel Previous Comments: ------------------------------------------------------------------------ [2005-04-04 11:19:54] vrana@php.net This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. "FALSE is returned both in the case of an error and if unserializing the serialized FALSE value. This special case can be catched by comparing str parameter with serialize(false) or by catching the issued E_NOTICE." ------------------------------------------------------------------------ [2005-04-01 17:30:45] didou@php.net I think we really should add the last sentence of Axel before closing the bug. ------------------------------------------------------------------------ [2005-04-01 17:14:38] vrana@php.net This bug has been fixed in the documentation's XML sources.

But it may also return a boolean: $bool = TRUE; $serbool = serialize($bool); $unserbool = unserialize($serbool); echo $serbool, '/', gettype($unserbool), '/', $unserbool? 'TRUE': 'FALSE'; --> b:1;/boolean/TRUE Changing TRUE to FALSE in the above yields: --> b:0;/boolean/FALSE The problem is that a FALSE value is by itself undistinguishable from an unserialization error, not that unserialize() cant' return a boolean.
