Php处理与Apache RewriteRules和RegExp：哪一个更快？

2022-10-03 07:39:58

我已经阅读了this,但它没有回答我的问题.

这是我的场景：我一直致力于我自己的框架,我为此感到自豪(多语言,模板等).
但我不得不面对一个问题：多语言和模板处理是在Php中完成的. 800行代码,分析主机,看看哪里看模板等等.虽然我没有测试它的效率,但它很混乱,我很确定它效率不高.它正在处理很多数组(array_push(),array_key_exists()等)

我已经重写了整个Php文件,现在它创建了自己的“缓存”文件,几乎所有工作都是由Apache完成的,然后再转到Php文件. Php文件只分析_GET中的内容.

但我担心一件事：RegExp快吗？在我以前的Php文件中,我使用array_xx()函数玩了很多,但之前绝对没有Apache RewriteRules.

我不知道RegExp性能,我不知道Apache RewriteRules和初始化环境变量所花费的时间.我做了很多(见后).所以,也许,在那些解释之后,有人可以告诉我“没问题,你的RegExp不复杂,Apache快速处理”,或“立即停止,你可能会遇到RegExp的麻烦”等等.

这是关于“Apache RegExp RewriteRules”和“Php处理URL而不是Apache”的性能的建议和警告.

这是我的所有RewriteRule,我只是想知道他们是否可能比我以前的Php文件更慢地减慢我的Apache Web服务器.

解决方法:

它将取决于您的服务器,内存等.唯一可以确定的方法是运行性能基准测试,看一下httperf.

主观上,我可以告诉你,我们的.htaccess工作中有大约450行重写规则,尽管最好尽可能少,但重写规则并不是应用程序的瓶颈(我们提供服务)每秒几千个请求).

所以,考虑到这一点,我不会太担心它.在重写规则是系统中最慢的部分之前,您更有可能遇到未经优化的数据库,缓存不足以及许多其他问题.

你的重写规则集似乎有点混乱,所以我会花一些时间将它组织成一个更有意义的url结构(并从旧的URL添加301重定向).您可以了解如何在常见的HMVC框架(如Kohana,Codeigniter或Symfony)中处理路由.
