The serialization and deserialization of objects are often used in web development. The more mainstream ones are the serialization and deserialization of json format and xml format. Today I wanted to write a small demo of jsop, but I found that I can't use php serialization. I checked the information and made a note. Simple array json format serialization/deserialization

PHP provides json_encode and json_decode functions to serialize/deserialize objects in json format

$data=array(&#39;Name&#39;=>&#39;Byron&#39;,&#39;Age&#39;=>24,&#39;Sex&#39;=>&#39;Male&#39;,&#39;Friends&#39;=>array(&#39;Cas

Simple array xml format serialization/deserialization

PHP provides wddx_serialize_value and wddx_deserialize functions to serialize/deserialize objects in XML format

$data=array(&#39;Name&#39;=>&#39;Byron&#39;,&#39;Age&#39;=>24,&#39;Sex&#39;=>&#39;Male&#39;,&#39;Friends&#39;=>array(&#39;Cas

## Although the output format is strange due to HTML transcoding, the serialized string is actually like this

Compared with the json format, there are many more fields

Complex object json format serialization/deserialization. Many times when we are operating, the object we process is not a simple array, but a custom object. Arrays, json_encode and json_decode are also competent. Customize an object similar to the above array content

class Me { public $name; public $age; public $friends; function __construct($name,$age,$friends) { 
$this->name=$name; $this->age=$age; $this->friends=$friends; } }

$me1=new Me(&#39;Byron&#39;,24,array(&#39;Casper&#39;,&#39;Frank&#39;,&#39;Vincent&#39;)); 
$me2=new Me(&#39;Casper&#39;,25,array(&#39;Byron&#39;,&#39;Frank&#39;,&#39;Vincent&#39;)); 
$me3=new Me(&#39;Frank&#39;,26,array(&#39;Casper&#39;,&#39;Byron&#39;,&#39;Vincent&#39;)); 
//创建一个复杂的数组，子元素是自定义类，自定义类中包含数组字段 
$array_me=array($me1,$me2,$me3); $json=json_encode($array_me);
//序列化对象数组为json字符串 echo $json.&#39;<br/>&#39;; $a=json_decode($json);
//将json字符串反序列化为对象数组 foreach ($a as $aa) { echo $aa->name.&#39;<br/>&#39;; }

You can see that the serialized string format is very consistent with expectations. Complex object XML format serialization/deserialization. The same wddx_serialize_value and wddx_deserialize functions are also capable of XML format serialization/deserialization operations on complex objects. Use the object just now as an example

$me1=new Me(&#39;Byron&#39;,24,array(&#39;Casper&#39;,&#39;Frank&#39;,&#39;Vincent&#39;)); 
$me2=new Me(&#39;Casper&#39;,25,array(&#39;Byron&#39;,&#39;Frank&#39;,&#39;Vincent&#39;)); 
$me3=new Me(&#39;Frank&#39;,26,array(&#39;Casper&#39;,&#39;Byron&#39;,&#39;Vincent&#39;)); 
//创建一个复杂的数组，子元素是自定义类，自定义类中包含数组字段 
$array_me=array($me1,$me2,$me3); $xml=wddx_serialize_value($array_me);
//序列化对象数组为xml字符串 echo $xml.&#39;<br/>&#39;; 
$a=wddx_deserialize($xml);
//将xml字符串反序列化为对象数组 
foreach ($a as $aa) { echo $aa->name.&#39;<br/>&#39;; }
