PHP uses memcache to store session method summary

Set session to use memcache to store

Method I: Set globally in php.ini
session.save_handler = memcache
session.save_path = "tcp://127.0.0.1:11211"

Method II: A certain directory .htaccess under
php_value session.save_handler "memcache"
php_value session.save_path "tcp://127.0.0.1:11211"

Method III: Or in a certain application

1 ini_set("session.save_handler", "memcache"); 
2 ini_set("session.save_path", "tcp://127.0.0.1:11211");

When using multiple memcached servers, separate them with commas ",", and as explained in the Memcache::addServer() document, you can take additional parameters "persistent", "weight", "timeout", "retry_interval", etc. , similar to this: "tcp://host1:port1?persistent=1&weight=2,tcp://host2:port2".

If the installed PECL is memcached (the extension that relies on the libmemcached library), the configuration should be
Php code collection code
ini_set("session.save_handler", "memcached"); // It is memcached, not memcache
ini_set(" session.save_path", "127.0.0.1:11211"); // Don't tcp:[/b]

Code example (the one that does not depend on the libmemcached library)

 1 <?php 
 2 session_start(); 
 3 if (!isset($_SESSION['TEST'])) { 
 4 $_SESSION['TEST'] = time(); 
 5 } 
 6 
 7 $_SESSION['TEST3'] = time(); 
 8 
 9 print $_SESSION['TEST']; 
10 print "<br><br>"; 
11 print $_SESSION['TEST3']; 
12 print "<br><br>"; 
13 print session_id(); 
14 ?>

Use sessionid to check in memcached:

<?php $memcache= memcache_connect('localhost', 11211); var_dump($memcache->get('19216821213c65 cedec65b0883238c278eeb573e077')); $ memcache->set('aaaa', 'hello everyone'); var_dump($memcache->get( 'aaaa' )); ?> sion normal Work. The above introduces the summary of PHP's use of memcache to store session methods, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
