在PHP中缓存对象的最佳方法？ [英] Best method to cache objects in PHP?
问题描述
我目前正在开发一个大型网站来处理用户注册。为了争辩而建立的社交网站。但是，我注意到页面加载存在滞后，并认为是在页面上创建对象使事情变慢。
I'm currently developing a large site that handles user registrations. A social networking website for argument's sake. However, I've noticed a lag in page loads and deciphered that it is the creation of objects on pages that's slowing things down.
例如，我有一个Member对象，当使用作为构造参数传递的ID实例化时，它将在数据库中查询成员数据库表中该成员的行。不错，但这是在每次加载页面时创建的；然后说了不止一次，说了一次，调用了该特定成员的朋友的数组，因为为每个朋友创建了一个新的Member对象。
For example, I have a Member object, that when instantiated with an ID passed as a construct parameter, it queries the database for that members' row in the members database table. Not bad, but this is created each time a page is loaded; and called more than once when say, calling an array of that particular members' friends, as a new Member object is created for each friend.
因此，我在单个页面上最多可以有七个相同的对象，但是包含不同的属性。
So on a single page I can have upwards of seven of the same object, but containing different properties.
我要做的就是找到一种减少数据库负载的方法，并允许页面加载之间的持久对象。例如，要在登录时创建登录用户的对象（我可以这样做），然后将其存储在某个地方以供检索，这样我就不必在页面加载之间继续创建对象。
What I'm wanting to do is to find a way to reduce the database load, and to allow persist objects between page loads. For example, the logged in user's object to be created on login (which I can do) but then stored somewhere for retrieval so I don't have to keep re-creating the object between page loads.
什么是最佳解决方案？我看过Memcache，但由于它是第三方模块，因此我无法让网络托管服务商在此情况下安装它。在我的情况下，我有什么选择和/或最佳做法？
What is the best solution for this? I've had a look at Memcache, but with it being a third-party module I can't have the web host install it on this occasion. What are my alternatives, and/or best practices in my case?
预先感谢。
推荐答案
我认为通常最好缓存从数据库接收的数据，而不是PHP对象本身。无论哪种方式， APC ， Memcache 或 XCache 是存储它的方式。
I believe it's generally better to cache the data received from the database, not the PHP object itself. Either way, APC, Memcache or XCache would be the way to store it.
