Convert a string to a readable form?

Cannot determine how to convert this string into an array, or other readable form, at first I thought that json.
There is such a line:
a:39:{s:15:"curr_session_id";s:32:"33c9067723114ad7e5a0f1b6503b5c5b";s:18:"start_session_time";s:19:"2016-06-09 20:37:43";s:4:"hash";s:32:"954c2c4075093e3068ab7f418c7c1fa0";s:2:"id";s:1:"1";s:6:"ulogin";s:5:"admin";s:5:"email";s:5:"admin";s:5:"ugrps";a:1:{i:0;s:3:"z24";}s:10:"login_time";i:1465493863;s:2:"ip";s:13:"188.163.37.90";s:7:"expired";i:0;s:5:"token";s:18:"ac5951f258ef0cc0da";s:5:"login";s:5:"admin";s:4:"name";s:5:"admin";s:7:"surname";s:0:"";s:7:"midname";s:0:"";s:3:"fio";s:5:"admin";s:3:"sex";s:1:"1";s:6:"avatar";s:11:"8779438.jpg";s:7:"blocked";s:1:"0";s:14:"blocked_reason";s:0:"";s:5:"admin";s:1:"1";s:7:"balance";s:6:"731.00";s:4:"role";s:1:"1";s:9:"activated";s:1:"1";s:3:"pro";s:1:"0";s:10:"pro_expire";s:19:"2013-05-15 09:51:40";s:6:"master";s:1:"0";s:13:"master_expire";s:19:"0000-00-00 00:00:00";s:11:"rent_expire";s:19:"0000-00-00 00:00:00";s:3:"adv";s:1:"0";s:14:"opinions_cache";s:181:"+1 0 -0";s:3:"icq";s:6:"123456";s:5:"skype";s:8:"domuspro";s:6:"emails";s:35:"a:1:{i:0;s:17:"admin@domuspro.ru";}";s:6:"phones";s:34:"a:1:{i:0;s:16:"8-800-0000-00-00";}";s:5:"sites";s:29:"a:1:{i:0;s:11:"domuspro.ru";}";s:7:"city_id";s:4:"2341";s:10:"city_title";s:22:"Novosibirsk";s:18:"curr_db_session_id";s:32:"f8cf525f5a91fa5668760390e03eb3f7";}
