※ 引述《kenshieh ( )》之铭言： : 请问在 PHP 中是否有可能实现 connection pool ？ : 试了各式各样的方法，几乎都无法把 Resource #id 存起来，不知是否有其它解决方法 : 呢？ 谢谢。 :> pooling 应该是 apache 所做的事情吧 曾经看过一篇 Rasmus Lerdorf（php 之父）的 interview 对於 pooling 这个问题有以下的回应（SP为记者；RL则是 Rasmus Lerdorf)： [原文： http://www.sitepoint.com/article/phps-creator-rasmus-lerdorf/4 ] x x x SP: What about database connection pooling? Persistent connections are not nearly good enough - are there plans to implement connection pooling in the future? RL: A pool of connections has to be owned by a single process. Since most people use the Apache Web server, which is a multi-process pre-forking server, there is simply no way that PHP can do this connection pooling. It has to be done by a dedicated standalone process and is quite outside the scope of PHP itself. Both SQLRelay and SRM can be used to solve this problem. If/when the common architecture for PHP is a single-process multithreaded Web server, we might consider putting this functionality into PHP itself, but until that day it really doesn't make much sense. Even Apache 2 is still going to be a multi-process server with each process being able to carry multiple threads. So we could potentially have a pool of connections in each process. x x x 如果要达到类似 connection pooling 的效果，应该是使用 persistent connections； 至少它在连结之前，会先查看是否与资料库间已建有连结，若已建立便使用该连结， 若无才会建立新的。 --
