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

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

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),
