PHP是一门高效的网络编程语言，由于它具有编写灵活、运行快速等优点，迅速成为Web程序员的首选语言。那么怎样才能成为一个优秀的PHP开发者呢?
要成为一名PHP编程高手并不容易，并不像很多人想象的那样，只要能够飞快地编写几条简单的代码去解决一个复杂的问题就是PHP编程高手了，真正的PHP高手还需要考虑更多的其它问题。以下三条准则是一名成熟的PHP程序员在编程中应该首先遵循的准则。
◆懒惰是金
◆编写漂亮的代码
◆追求程序的速度，而不是编程的速度
懒惰是金
做一个懒惰的程序员吗?这个想法太奇怪了!因为这个世界上最忙碌的人可能就是计算机程序员了。但正是因为程序员太忙了，所以才应该在编程时学会偷懒。对于一个程序员来说，懒惰的方法有两种：
其一，大胆使用现成的别人的程序代码，把这些代码融入到你自己的程序或者项目中去。其二是编写一些有用的代码建立一个函数库，在将来编写程序时可以顺手拈来，省去了许多重复的劳动，自然就可以懒惰一点了。这两种偷懒的方法都非常适合PHP程序员了。
首先，PHP是在自由开放的环境中诞生和成长的一门语言。在世界各地，有成千上万的程序员，他们一直在为PHP的完美而不断奋斗，他们也愿意和别人分享自己的聪明才智和自己编写的代码。你每天都可以从一些PHP网站、邮件列表、新闻组发现大量的优秀的程序代码。
这样说，我并不是鼓励你整天等着让别人为你编写代码，但是你可以“站在伟人的肩膀上”，充分发扬“拿来主义”，聪明地应用别人的程序代码可以节省你大量时间。其次，在PHP中，你可以方便地建立自己的函数库，这样可以在你以后编写程序时省去很多麻烦。
下面笔者为大家介绍几个通用的函数，这些函数有的来自网上的一些开放源代码的项目，有的精选自邮件列表。如果你能把它们加入到你自己的函数库中，迟早你将会发现自己受益无穷。
1.通用数据库处理函数
和其它的CGI函数相比，PHP的优点之一是具有很强大的数据库处理能力。但是，在PHP中，对于不同的数据库都使用一些特定的函数来专门处理，缺少通用的数据库处理函数。这大大降低了程序代码的可移植性，这也为初学编程的朋友带来了很多不便。

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
