PHP provides two functions: serialize serialization and unserialize deserialization. What is the use of these two functions? Serialization can serialize any data type in PHP into a string except resource. Here, we take an object as an example to define a class Vb {private $ A; private $ B; function _ construct ($ A = 'peng', $ B = 'luo') {$ this-> A = $ A; $ this-> B = $ B ;} public Function speak () {return $ this->. $ this-> B ;}}$ OBJ = new VB (); We serialize $ OBJ $ c = serialize ($ OBJ); after printing $ C, we get o: 2: "VB": 2 {s: 5: "VBA"; s: 4: "peng"; s: 5: "vBB"; s: 3: "Luo";} We Will deserialize this string, $ c = unserialize ($ C); print print_r ($ C); Vb object ([: private] => Peng [B: Private] => LUO) Now we get an object. We can call the attributes and methods of the object echo $ C-> speak (); in fact, these two functions are not difficult, but many people do not know when to use them. What is the use of these functions, when you want to save a complex data type to a file or database, you can see its role.
