PHP Load Balancer Session Shared _php Tutorial

It's been a long time since I've been working on the fourth edition of the Taiwan Lottery, so it's been a while since I've been writing something and sharing it with you today.

First of all, I believe we all know that the load balance can be very good to solve the problem of large traffic network, load balance is to the user's request to the multi-state PC to go to the processor, Since the division has been made, please consider the process of dealing with the session. In the case of PHP, the session will be stored in the temporary file of the machine, but in this case the session is lost, the simplest solution is to use memcache to entrust, A single set of services for the Memcache service (the best is a big one), the next job to the PHP code to do it, I do not want to modify the php.ini, because every change is too tired, and I am more lazy

Or maybe you'll tell me that directly modifying the php.ini session storage location can be written into the memcache, yes, no wrong, but this way does not adjust the GC release of the session, and today we have to say not only to let him, but also let him release the conversation.

Since to do, it is necessary to achieve perfection, the next side is my code, do not know how to read the explanation:

$_env=array (' SYS ' =>array (' memip ' = ' 127.0.0.1 ',//memcache's IP ' mempt ' =>11211,//memcache ' port ' memtim ' = >10,//memcache);//The session to Memcache, if you open the failure, it is said that Memcache is not configured to the final class s{public static function open () {/ /disable Session Auto-start session_write_close (); Ini_set (' Session.auto_start ', 0);//use one-fiftieth probability to activate GC cleanup session ini_set (' Session.gc_ Probability ', 1); Ini_set (' session.gc_divisor '); Ini_set (' session.use_cookies ', 1);//session's Life//ini_set (' Session.gc_maxlifetime ', $_env[' sys ' [' memtim ']);//ini_set (' Session.cookie_lifetime ', $_env[' sys ' [' memtim ']);// Ini_set (' Session.save_handler ', ' files '),//ini_set (' Session.save_path ', Run.        _tmp ');//ini_set (' Session.save_handler ', ' memcache ');//ini_set (' Session.save_path ', ' tcp://127.0.0.1:11211 '); $_env[' S_tim ' = Ini_get (' session.gc_maxlifetime ');//Establish Memcache-like $_env[' S_mem ']=new memcache;$_env[' s_mem ']-        >connect ($_env[' sys '] [' MEMIP '],$_env[' sys ' [' mempt ']) or Die (' Memcache connection failed! ');    return TRUE; }/** Read back: Read content/**/public static FuNction Read ($id) {return $_env[' S_mem ']->get (' S_ '. $id); }/** write-In return: bool/**/public static function write ($id, $data) {return $_env[' S_mem ']->set (' S_ '. $id, $data, MEMCACHE    _compressed,$_env[' SYS ' [' Memtim ']); }/** closed return: bool/**/public static function close () {$_env[' S_mem ']->close (); unset ($_env[' s_mem '],$_env[' SYS '] [' Memtim ']); return TRUE;}    /** Delete return: bool/**/public static function Destroy ($ID) {return $_env[' S_mem ']->delete (' S_ '. $id); }/** cleanup return: bool/**/public static function gc () {return TRUE;}} Session_set_save_handler (' S::open ', ' s::close ', ' s::read ', ' s::write ', ' S::d Estroy ', ' s::gc '); $_env[' SessionID ']= ( Isset ($_request[' SessionID '))? Trim ($_request["SessionID"]): session_id (); if ($_env[' SessionID ']!= ') {session_id ($_env[' SessionID ']);} Session_Start ();
