PHP memcached 基础应用

<?php

//连接
$mem = new Memcache;
$mem->connect("127.0.0.1", 11211) or die ("Could not connect");
//显示版本
$version = $mem->getVersion();
echo "Memcached Server version: ".$version."<br>";
//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>";

//对数组进行序列化,在网络传输的时候，为了保证，数据类型的不丢失，先序列化，再发生.
$arr1=serialize($arr);
$arr2=json_encode($arr1);

print_r($arr2);

//删除数据
$mem->delete('key1');
$val = $mem->get('key1');
echo "<br>Get key1 value: " . $val . "<br>";
//清除所有数据
$mem->flush();
$val2 = $mem->get('key2');
echo "Get key2 value: ";
print_r($val2);
echo "<br>";
//关闭连接
$mem->close();
