Working with Joomla and Wordpress CMSs, I found weird rows in both of them, for example WordPress has a row in wp_options table called wp_user_roles which filled with a:8:{s:13:"administrator";a:2:{s:4:"name";s:13:"Administrator"... which i don't call it JSON but obviously its something very similar, I just want to know what it is, also I couldn't find any function to parse it in php easily.
This is not JSON, but serialized
As commented by Nigel Ren, in this Question (How to use php serialize() and unserialize()) serialize and unserialize are explained
