PHP Serialization and deserialization

PHP serialization simply means compressing a complex data type into a string in which the PHP object is converted to a string, and deserialization is the conversion of the variable into an object.

In general, when you place these serialized data in a URL and pass between pages, you need to call UrlEncode () on the data to ensure that the URL metacharacters are processed

More often, we will try to make an array stored in an array with serialization, compared to the need to store multiple fields, more practical

　　$arr = Array (' AC ', ' AC ', ' ad ', ' BB ');

　　$ser = serialize ($arr);//serialization

　　$ser = Unserialize ($ser);//deserialization
