When fetching an object, be aware that the class you want to fetch is declared earlier. Just like the session.

mem1.php

  $mem= new Memcache ();if($mem->connect (' 127.0.0.1 ',11211)){Echo' Connection succeeded
';}Else{Echo' Connection failed
';} Increase//1. Add a string/*if($mem->add (' Key1 ',' Shanghai ', memcache_compressed, -)){Echo' Add success

';} *///3Add an array//when adding an array, as needed, you want to deposit after serialization. serialize//can also Json_encode ()/* if required$arr= Array (' AAA ',' BBB ',' CCC ');if($mem->add (' Key1 ',$arr, memcache_compressed, -)){Echo' Add success

mem2.php

    
     //在这个文件去 memcache 对象$mem = new Memcache();classDog{public$name;    public$age;    publicfunction__construct($name,$age)    {$this->name = $name;        $this->age = $age;    }}if ($mem->connect('127.0.0.1',11211)){    echo'连接成功
';}else{    echo'连接失败
';}//在另外文件取对象$dog = $mem->get('key1');var_dump($dog);

index.php

   !--? php    class   Dog     {  public   $name ;  Public      $age ;  Public    function   __construct   ( $name ,  $age )  {         $this ->name =  $name ;     $this ->age =  $age ; }}  $dog 2  =  new  Dog ( ' small ha ' ,  + ); //Save this object to disk--serialize, the string can be transmitted online  //Traditional methods  //file_put_contents ('./dog.log ', $dog 2);//cannot be saved, is empty  //Serialization  file_put_contents ( './dog.log ' , serialize ( $dog 2 )); //Can be saved, and can be deserialized when taken out   Echo   ' Save OK

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

The above describes the 4 PHP operation Memcached1, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
