在WEB开发世界里,PHP是最流行的语言之一,从PHP里,你能够很容易的找到你所需的脚本,遗憾的是,很少人会去用“最佳做法”去写一个PHP程序。这里,我们向大家介绍PHP的10种最佳实践,当然,每一种都是经过大师们证明而得出的。 1. 在合适的时候使用PHP – Rasmus Lerdorf 没有谁比PHP的创建者Rasmus Lerdorf明白PHP用在什么地方是更合理的,他于1995年发布了PHP这门语言,从那时起,PHP就像燎原之火,烧遍了整个开发阵营,改变了互联网的世界。可是,Rasmus并不是因此而创建PHP的。PHP是为了解决WEB开发者的实际问题而诞生的。 和许多开源项目一样,PHP变得流行,流行的动机并不能用正常的哲学来进行解释,甚至流行得有些孤芳自赏。它完全可以作为一个案例,一个解决各种Web问题的工具需求所引起的案例,因此当PHP刚出现的时候,这种工具需求全部聚焦到PHP的身上。 但是,你不能奢望PHP可以解决所有问题。Lerdorf是第一个承认PHP只是一种工具的人,并且PHP也有很多力所不能及的情况。 根据工作的不同来选择合适的工具。我跑了很多家公司,为了说服他们部署和使用PHP,但是这并不意味着PHP对所有问题都适用。它只是可以一个解决大部分问题的front-end脚步语言。 作为一个web开发者,尝试用PHP解决所有问题是不科学的,同时也会浪费你的时间。当PHP玩不转的时候,不要犹豫,试用一下其他的语言吧。 2. 使用多表存储提高规模伸缩性 – Matt Mullenweg 没有人愿意质疑Matt Mullenweg在PHP方面的权威性,他开发了这个星球上最流行的blog系统,(依靠一个强大的社区力量支持): WordPress. 创建Wordpress以后,Matt和他的团队启动了WordPress.com平台,一个基于WordPress MU的免费blog站点。现在,Wordpress.com已经拥有大约400万用户, 这些用户每天提供超过 140,000篇的日志。 (要查看更多Wordpress.com的统计情况,请点击这里.) 如果有人知道如何让网站的规模伸缩自如,这个人一定是Matt Mullenweg。2006年的时候 Matt对Wordpress的数据结构进行了前瞻性的改进,并且解释了为什么Wordpress MU对每个blog使用独立的MYSQL表格, 而不是把所有的blog数据都塞进一个巨大的表格。 我们测试过这个方法,但是发现如果要扩展它的伸缩性,代价太高。如果用一个整体的数据结构,在大流量面前,你将会面临服务器硬件的问题。在MU里面。用户们都被分布到独立的表格当中,并且可以轻易地组织起来。举个例子,WordPress.com把用户的数据分散存储到4096个数据库中,这些数据库可以分散大规模的数据访问,实现流量和压力分流。 数据表的可迁移性让代码(blog)可以运行得更快,并且让系统具备更强的伸缩性。依靠强大的缓存策略和灵活的数据库运用策略, Matt向人们展示了时下最流行的Facebook和Wordpress.com都可以在PHP下稳定运行,并且处理惊人的访问量。 3. 千万不要相信用户 – Dave Child Dave Child是Added Bytes (previously ilovejackdaniels.com) 网站的核心人物,这个网站以他出色的《cheat sheets for many programming languages》而闻名。 Dave为很多英国的公司服务,并且已经在编程世界里树立起相当的权威。 […]
