PHP连接memcached

 

##########################telnet连接

telnet 192.168.3.3 11211

stats

add abc 0 60 5

hello

add 是指令名  

abc是key的名字 (是以key/value存放), 

0 标志, 

60 表示数据存放 60s   

5表示 放入多大数据  

如果一个key已经存在，再放入是失败的

get abc

#######################php测试脚本

<?php

//连接

$mem = new Memcached;

$mem->addServer("192.168.16.31", 11211) or die ("Could not connect");

//$mem = memcache_connect('192.168.16.31', 11211);

//保存数据

$mem->set('key1', 'This is first value', 0, 60);

$val = $mem->get('key1');

echo "Get key1 value: " . $val ."</br>";

//替换数据

$mem->replace('key1', 'This is replace value', 0, 60);

$val = $mem->get('key1');

echo "Get key1 value: " . $val . "<br>";

//保存数组

$arr = array('aaa', 'bbb', 'ccc', 'ddd');

$mem->set('key2', $arr, 0, 60);

$val2 = $mem->get('key2');

echo "Get key2 value: ";

print_r($val2);

echo "<br />";

//删除数据

$mem->delete('key1');

$val = $mem->get('key1');

echo "delete key1<br>";

echo "Get key1 value: " . $val . "<br />";

//清除所有数据

$mem->flush();

echo "delete all<br>";

$val2 = $mem->get('key2');

echo "Get key2 value: ";

print_r($val2);

echo "<br />";

//关闭连接

$mem->quit();

?>

PS：memcached 连接服务器改成：

public bool addServer ( string $host , int $port [, int $weight = 0 ] )

public bool addServers ( array $servers )

关闭连接改成：

public bool Memcached::quit ( void )
