Generally, the unserialize() function takes two parameters, str and options the str is one of the parameters it contains serialized strings waiting for to be deserialized, and options are one of the arrays it contains for the control for certain function behaviors it accepts only for valid users particularly inbuilt classes like allowed_classes.It also secured with the code injections and even db end it will avoid some sql injections attacks for untrusted malware sites. So it will be avoided for some other malwares, viruses from the outside of the machine. Using these serialize and unserialize() functions always return the Boolean conditions it will be to secure and more protected on the unserializing objects, or we can call it as untrusted datas. Then only we accessed the data it is also used for the file concepts. If we want to access the data, we want to deserialize the datas or unserialize the datas in the code. The unserialize function depends on the serialize function whatever the datas are called and used on that function, it will be fully serialized with keys.
