Unserialize through query at database level itself

Question

I have a column value stored in the database as:

a:2:{i:0;s:2:\"US\";i:1;s:2:\"19\";}

I want to unserialize it during the mysql

Answer 1

How about this? This is a MySQL user-defined function with embedded php:

CREATE FUNCTION unserialize_php RETURNS STRING SONAME 'unserialize_php.so';

Usage example:

SELECT unserialize_php('O:8:"stdClass":2:{s:1:"a";s:4:"aaaa";s:1:"b";s:4:"bbbb";}', "$obj->a") 
AS 'unserialized';

+--------------+
| unserialized |
+--------------+
| aaaa         |
+--------------+
1 row in set (0.00 sec)

drop function unserialize_php;

You can create a MySQL user-defined function and call zend_eval_string inside of the function so that you can bring back PHP variables to a MySQL result. I implemented a sample program. You can try it.
