企业不应该避免使用PHP开发应用。一些人认为,比起其它选择,PHP太不安全了。这种说法也很不客观。
WhiteHat Security(白帽安全)公司最近发布了研究,他们使用自动化的工具查看1700个web站点,看看安全bug的数量和建立站点使用的编程语言之间是否有任何关联。总体的结论是,没有一种语言是“最安全的”。研究表明,某些语言确实有益于结构化地编写,易于管理代码,且某些框架提供默认开启的安全控制。PHP可能名声更坏,因为它不仅被广泛地使用,而且垃圾邮件发送者们利用了许多不安全的PHP形式来发送垃圾邮件(通过邮件注入)。
甚至最忠实的PHP迷也会同意,对于一个未经培训的程序员来说,用像PHP一样的语言更容易写出不安全的代码。因特网上有数以千计的例子和教程来解释如何使用PHP将一个花哨的功能添加到开发的应用中,但是它们中的大多数没有涵盖如何确保这些功能安全,不让应用容易受到攻击,因此功能丰富的PHP应用通常没有以安全的思维进行开发。
培训你的开发人员,让他们带着安全的思维来写代码,这比起语言的选择来说更为重要。CERT(Computer Emergency Response Team,计算机应急响应团队)发现,大多数应用中的漏洞来自开发人员不断重复犯的、一些数量相对少的常见编程错误。通过消除不安全的编码,并专注于安全编码培训,你的软件开发人员可以迅速地减少或消除漏洞的数量,直到软件最终上线。你可以用因特网上的许多优秀且免费的资源和教程来发展他们(开发人员)在这个领域的技能。这个领域的领导者之一是OWASP站点(Open Web Application Security Project,开放Web应用安全项目),它提供了许多关于如何安全编码的例子。
CERT安全编码的出发点是为常用的编程语言建立安全编码标准,并促进安全编码的最佳实践。另一个提高你的开发人员安全编码技能的好资源,是微软的MSDN安全社区和编写安全代码部分。那里有许多由微软软件安全专家Michael Howard撰写的各种书,你可能感兴趣的包括“编写安全的代码(Writing Secure Code)”、“软件安全的24个致命过错(24 Deadly Sins of Software Security)”和“安全开发生命周期(The Security Development Lifecycle)”。许多涉及的主题可以应用到任何一种编程语言,并会帮助你理解如何带着安全思维来编码:那就是,正确地使用安全功能并编写能够经受攻击的代码。
如果你开始将从这些资源中学到的融合起来,并且将安全嵌入到整个应用生命周期,无论你选择使用哪种语言,但愿你的下个应用会更加强健并且能够经受攻击。

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 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.

The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

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 content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Although Notepad cannot run Java code directly, it can be achieved by using other tools: using the command line compiler (javac) to generate a bytecode file (filename.class). Use the Java interpreter (java) to interpret bytecode, execute the code, and output the result.

To view the Git repository address, perform the following steps: 1. Open the command line and navigate to the repository directory; 2. Run the "git remote -v" command; 3. View the repository name in the output and its corresponding address.
