缓存PHP数组 [英] Caching a PHP Array

问题描述

我的问题是IM创造了大量的嵌套PHP数组是解析从多个外部来源的信息。

My problem is im creating a large nested PHP array which is parsing information from multiple external sources.

在第一回，我想缓存此数据。

On the first return I would like to cache this data.

林pretty新缓存所以真的不知道我应该寻找，任何好的或坏的方法或即使这是常见的做法！用Google搜索，但没有真正发现任何像样的缓存小白。

Im pretty new to caching so don't really know what I should be looking for, any good or bad methods or even if this is common practise! Have googled but not really found anything decent for a cache noob.

林已经在使用Smarty的缓存我的网页内容（不含动态位），完成apache的调整，污染减量等，以提高性能，但页面加载仍远长。有时高达8秒！

Im already using smarty to cache my page content (excluding the dynamic bits), done apache tweaks, minifying etc to increase performance but page loading is still far to long. Sometimes upto 8 seconds!

使用PHP5与Smarty的。使用cURL解析，然后存储到阵列的XML。

Using PHP5 with Smarty. Using cURL to parse the XML which is then being stored into the array.

推荐答案

您可以尝试缓存到一个文件：

You could try to cache to a file:

file_put_contents("cache_file", serialize($myArray));

然后加载缓存：

$myArray = unserialize(file_get_contents("cache_file"));

这将工作，如果你的数组中的东西都序列化：没有DB连接或文件句柄，或者类似的东西。字符串和数字就好了。

This will work if the things in your array are serializable: no DB connections or file handles, or things like that. Strings and numbers are just fine.

如果你需要的东西票友可以使用基于内存的缓存就像memcached的。

If you need something fancier you can use a memory-based cache like memcached.
