Refer to the PHP reference manual for specific studies:

Several ways to manipulate memcached:

BOOL Memcache::add (String $key, mixed $var [, int $flag [, int $expire]])

If the quote expire is set to 0 , it never expires . just memcache without restarting, it will always be in Mem in )

Exprie directly to the number of seconds, the maximum 30*3600*24

If you want to keep time longer than () + days *3600*24

When you remove an object from another file, there is a note that the corresponding php5.2 version will prompt for errors,
This version of php5.3 will prompt for incomplete information, and the workaround is to declare the class definition

mem2.php

<?php//this file to operate the Memcached service//Create a Mem object instance $mem=new Memcache;     if (! $mem->connect ("127.0.0.1", 11211)) {die (' Connection failed! ');} In the other file to remove the object, there is a note that the corresponding php5.2 version will prompt the error,//php5.3 This version will prompt incomplete information, the workaround is to declare the class definition can class Dog{public $name;p ublic $ Age;public function __construct ($name, $age) {$this->name= $name; $this->age= $age;}} $dog = $mem->get (' Key1 '); Var_dump ($dog);
