#48171 [Bgs]: Unserialize converts string to integer in case of numeric properties

ID: 48171 Updated by: jani@php.net Reported By: csnyder at fcny dot org Status: Bogus Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 5.2.9 New Comment: See bug #45959 Previous Comments: ------------------------------------------------------------------------ [2009-05-06 18:43:19] csnyder at fcny dot org Bogus really? If serialize handles numeric property names correctly, why shouldn't unserialize? Also, would be interested in actual citation in the manual as to why this bug is bogus. Thanks. ------------------------------------------------------------------------ [2009-05-06 18:39:06] jani@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php ------------------------------------------------------------------------ [2009-05-06 18:36:32] csnyder at fcny dot org Description: ------------ When unserializing a string like O:8:"stdClass":3:{s:5:"22387";s:1:"a";s:5:"22386";s:1:"a";s:5:"22368";s:1:"a";}, the resulting object will have integers as property names instead of strings. This may be regression of #43614, marked fixed in CVS but that was a year ago. Reproduce code: --------------- <?php // an object with some numeric keys $keys = array( "1", "2", "3" ); foreach( $keys AS $key ) { $obj->{$key} = 'a'; } var_dump( $obj ); $s = serialize( $obj ); $u = unserialize( $s ); var_dump( $u ); ?> Expected result: ---------------- object(stdClass)#1 (3) { ["1"]=> string(1) "a" ["2"]=> string(1) "a" ["3"]=> string(1) "a" } object(stdClass)#2 (3) { ["1"]=> string(1) "a" ["2"]=> string(1) "a" ["3"]=> string(1) "a" } Actual result: -------------- object(stdClass)#1 (3) { ["1"]=> string(1) "a" ["2"]=> string(1) "a" ["3"]=> string(1) "a" } object(stdClass)#2 (3) { [1]=> string(1) "a" [2]=> string(1) "a" [3]=> string(1) "a" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48171&edit=1
