php的数据对象、构造的存储

php的数据对象、结构的存储

1.使用序列化和反序列化函数, 然后将序列化结果$result存储到文件或者数据库中进行持久存储

$result = serialize($data);

 

$data = unserialize($result) 

 

2.使用分布式内存对象缓存系统 memcached

2.1安装memcached客户端 将数据存储在该客户端的内存中

win32版memcached http://code.jellycan.com/memcached/

可安装为服务

 

memcached -d install

memcached -d start

 

2.2安装php扩展

下载 http://shikii.net/blog/downloads/php_memcache-cvs-20090703-5.3-VC6-x86.zip

编辑php.ini extension=php_memcache.dll

示例代码：

 

 

<?php

$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");

$version = $memcache->getVersion();
echo "Server's version: ".$version."<br/>\n";

$tmp_object = new stdClass;
$tmp_object->str_attr = 'test';
$tmp_object->int_attr = 123;

$memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server");
echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";

$get_result = $memcache->get('key');
echo "Data from the cache:<br/>\n";

var_dump($get_result);

?>
