How PHP can serialize and deserialize data

This article mainly introduces how to serialize and deserialize the data of PHP, the interested friend's reference, I hope to help you.

PHP actually uses two functions,serialize and Unserialize, to serialize and deserialize data.
serialize formatting an array into an ordered string
unserialize to restore an array to a group
For example:

$user =array (' Moe ', ' Larry ', ' Curly '); $user =serialize ($stooges); Echo ' <pre> '; Print_r ($user); echo ' <br/> '; Print_r (Unserialize ($user));

Results:

A:3:{i:0;s:3: "Moe"; I:1;s:5: "Larry"; I:2;s:5: "Curly";} Array ([0] = Moe [1] = Larry [2] = Curly)

Note that when the array values contain characters such as double quotes, single quotes, colons, or Chinese, they are deserialized, and the problem of garbled or scrambled formatting can occur.

To solve garbled problems, you can use base64_encode and Base64_decode two functions.
For example:

$user =array (' Moe ', ' Larry ', ' Curly '); $user =base64_encode (Serialize ($user)); $user =unserialize (Base64_decode ($user));

This will not show the problem of garbled class, but the base64 encoding increases the length of the stored string .

From the above we can summarize one of our own serialization and deserialization functions , as follows:

function my_serialize ($obj _array) {   return Base64_encode (gzcompress (Serialize ($obj _array))}//Deserialization function my _unserialize ($str) {   return unserialize (gzuncompress (Base64_decode ($STR)));}

Summary: The above is the entire content of this article, I hope to be able to help you learn.
