如何从解密的字符串中读取数据[关闭]

Question

string(284) "a:4:{s:10:"session_id";s:32:"01a046827a00cf838a1b3ce585cc82fb";s:10:"ip_address";s:13:"124.43.56.156";s:10:"user_agent";s:120:"Mozilla/5.0 (Windows; U; Windows NT 6.2; en-US) AppleWebKit/533.20.25 (KHTML, like Gecko) Version/5.0.4 Safari/533.20.27";s:13:"last_activity";i:1371099813;}"

This is a decrypted cookie from CodeIgniter. I need to access data from this. Preferably convert to an array or something which is easily accessible like data -> session_id. Which would be the possible way to extract data from this?

Answer 1

Just unserialize it.

var_dump( unserialize('a:4:{s:10:"session_id";s:32:"01a046827a00cf838a1b3ce585cc82fb";s:10:"ip_address";s:13:"124.43.56.156";s:10:"user_agent";s:120:"Mozilla/5.0 (Windows; U; Windows NT 6.2; en-US) AppleWebKit/533.20.25 (KHTML, like Gecko) Version/5.0.4 Safari/533.20.27";s:13:"last_activity";i:1371099813;}'));
