设置session用memcache来存储
方法I: 在 php.ini 中全局设置
session.save_handler = memcache
session.save_path = "tcp://127.0.0.1:11211"
方法II： 某个目录下的 .htaccess
php_value session.save_handler "memcache"
php_value session.save_path "tcp://127.0.0.1:11211"
方法III： 再或者在某个一个应用中
<span 1</span> <span ini_set</span>("session.save_handler", "memcache"<span );
</span><span 2</span> <span ini_set</span>("session.save_path", "tcp://127.0.0.1:11211");
使用多个 memcached server 时用逗号","隔开，并且和 Memcache::addServer() 文档中说明的一样，可以带额外的参数"persistent"、"weight"、"timeout"、"retry_interval" 等等，类似这样的："tcp://host1:port1?persistent=1&weight=2,tcp://host2:port2" 。
如果安装的PECL是memcached(依赖libmemcached库的那个扩展)，则配置应为
Php代码 收藏代码
ini_set("session.save_handler", "memcached"); // 是memcached不是memcache
ini_set("session.save_path", "127.0.0.1:11211"); // 不要tcp:[/b]
代码例子(不依赖libmemcached库的那个)
<span 1</span> <?<span php
</span><span 2</span> <span session_start</span><span ();
</span><span 3</span> <span if</span> (!<span isset</span>(<span $_SESSION</span>['TEST'<span ])) {
</span><span 4</span> <span $_SESSION</span>['TEST'] = <span time</span><span ();
</span><span 5</span> <span }
</span><span 6</span>
<span 7</span> <span $_SESSION</span>['TEST3'] = <span time</span><span ();
</span><span 8</span>
<span 9</span> <span print</span> <span $_SESSION</span>['TEST'<span ];
</span><span 10</span> <span print</span> "<br><br>"<span ;
</span><span 11</span> <span print</span> <span $_SESSION</span>['TEST3'<span ];
</span><span 12</span> <span print</span> "<br><br>"<span ;
</span><span 13</span> <span print</span> <span session_id</span><span ();
</span><span 14</span> ?>
用 sessionid 去 memcached 里查询一下：
<?php
$memcache = memcache_connect('localhost', 11211);
var_dump($memcache->get('19216821213c65cedec65b0883238c278eeb573e077'));
$memcache->set('aaaa', 'hello everyone');
var_dump($memcache->get('aaaa'));
?>
会看到
string(37) "TEST|i:1177556731;TEST3|i:1177556881;"
这样的输出，证明 session 正常工作。
