How to serialize and deserialize data in php

This article mainly introduces how to serialize and deserialize data in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

php actually uses two functions to serialize and deserialize data, serialize and unserialize.
serialize Format the array into an ordered string
unserialize Restore the array into an array
For example:

$user=array('Moe','Larry','Curly'); 
$user=serialize($stooges); 
echo &#39;<pre class="brush:php;toolbar:false">&#39;; 
print_r($user); 
echo &#39;<br />&#39;; 
print_r(unserialize($user));

Result:

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 value contains characters such as double quotes, single quotes, colons or Chinese characters, they may be deserialized after being deserialized. There will be problems with garbled characters or disrupted formatting.

To solve the problem of garbled characters, you can use the two functions base64_encode and base64_decode .
For example:

$user=array('Moe','Larry','Curly'); 
$user=base64_encode(serialize($user)); 
$user=unserialize(base64_decode($user));

This way there will be no garbled code problems, but base64 encoding increases the length of the stored string.

From the above we can summarize a own serialization and deserialization function, as follows:

function my_serialize($obj_array){ 
  return base64_encode(gzcompress(serialize($obj_array))); 
} 
//反序列化 
function my_unserialize($str){ 
  return unserialize(gzuncompress(base64_decode($str))); 
}

Summary: The above is The entire content of this article is hoped to be helpful to everyone's study.
