也谈PHP面向对象编程_PHP

昨天转贴了一篇卢占斌写的关于PHP的OOP的文章~ 然后想说说自己对PHP面向对象编程的感受~

曾看见有人说PHP和PERL简直一模一样有了PERL还要PHP干吗

那么我就要问他了人都是一样的既然已经有那么多人了要你干吗~也许你要说每一个人都是不一样的就是啦事物都是不一样的而且即使一样既然已然现世何必不好好得活一场来证明自己比另一个或另一些好呢



对于PERL我确实接触很好也从没有认真去使用过他只是很久以前看过一些基本的东西在我看来他是及不上Python的~Python已经有10几年的历史只是他似乎不在意推广但事实上Python在很多地方都有应用比如大名鼎鼎的RedHat Lunix的安装脚本就是他制作的而且他早于JAVA前不知道多久就使用虚拟机了~



PHP很纯粹
我一直这么认为从一开始的简单到现在的复杂他虽然也在走大合……的路但怎么说在许多网络上的引用还是局限于脚本于是他真的很纯粹……很讨人喜欢。但有时候也会很不爽因为不够强大当然如果你实力够你完全可以自己开发PHP的模块……但这样做显然不怎么值得……



翻开PHP的PEAR
哇~



我曾很愚蠢的对人说PHP没有构造函数~看来真是想毛主席说的不懂就不要瞎说……



PHP不仅带有构造函数
而且~还能方便的重载构造函数~~

如下
:






class MyClass {



var $MyVar;



function MyClass() {



$this->MyVar = "I am iZzzzzzzzzzzzz";



}



}





$test = new MyClass;



echo $test->MyVar;



?>









关于重载构造
见前几天的那篇文章~



PHP中对封装
继承多态都做的非常好~



一些人可能会说PHP不是一个真正的面向对象的语言
这是事实。PHP是一个混合型语言你可以使用OOP也可以使用传统的过程化编程。然而对于大型项目你可能想/需要在PHP 中使用纯的OOP去声明类而且在你的项目只用对象和类。随着项目越来越大使用OOP可能会有帮助OOP代码很容易维护容易理解和重用。这些就是软件工程的基础。在基于web的项目中应用这些概念就成为将来网站成功的关键。



事实上就虽然OOP是软件工程的核心
但假如你连面向过程都做不好~那么你是肯定写不好OOP的代码的~肯定



前几天贴的那文章真的很不错……很值得大家一看

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Best Practices for Dependency Injection in PHPBest Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
