php下memcache结合数据库

下面演示一个PHP实例:

<?php

$mem=new Memcache;

$mem->connect("127.0.0.1",11211);

$sql="select * from db_it168_cpu";

$key=substr(md5($sql),10,8);

$data=$mem->get($key);

if(!$data)

{

$mysqli=new mysqli("localhost","root","","computer");

$result=$mysqli->query($sql);

$data=array();

while($row=$result->Fetch_assoc()){

$data[]=$row;

}

$result->free();

$mysqli->close();

$mem->add($key,$data, MEMCACHE_COMPRESSED,3000);

echo $sql;

}

print_r($data);

$mem->close();

?>

这个代码很简单,只是一个说明例子,你懂的!
