关于PHP文件树的问题,求解释。
PHP scripts that are used to connect to the database need access to the password for
that user.This can be done reasonably securely by putting the login and password in a
file called, for example, dbconnect.php, that you then include when needed.This script
can be carefully stored outside the web document tree and made accessible only to the
appropriate user.
我初学网页编程,看的是PHP和MySQL Web开发,我想问下这句话怎么理解。
This script can be carefully stored outside the web document tree and made accessible only to the appropriate user.
不把脚本放在文件树下,那上传到虚拟空间后,怎么访问这个脚本呢?
------解决方案--------------------
需要的时候全路径包含,
基于安全方面的原因。
------解决方案--------------------
文件数,就是除了敏感文件之外的所有网站运行需要的文件.
这个敏感文件包括, 连接数据库的用户名和密码等.
MYSQL文件夹是数据库层面的,这个可以通过导入导出来完成数据的初始化和备份操作,不在这个讨论范围之内.
------解决方案--------------------
首先,这句话是给有服务器控制权的建议――放到网站目录以外,用绝对路径引入
这主要是防止意外的情况匿名访问者能看到php源代码,例如php解析突然出现问题,php文件原文显示了
又或者忘了加容错和隐藏错误信息,连接数据库的php文件名暴露了
虚拟空间的数据库一般都不允许外来访问,只能本地127.0.0.1连接,所以密码外泄在短时间内还是不用担心的,尽快改密码就行
至于黑客行为,就不是这里所能解决的事了
------解决方案--------------------
安全是相对的
虽然 dbconnect.php这个包含密码 但也要进入到文件系统才能看到
如果入侵者能够进入虚拟空间的文件系统,那么他有什么不可以做的呢。即便你的dbconnect.php没放在web管辖范围,不还是一样能看到吗。更何况数据库里面还有一份呢?
------解决方案--------------------
如果你的密码用php语句赋值,而不是一个txt或ini,这样用http连接是看不出来的,只有php解析出错才会显示
因为虚拟空间通常限制只能本机连接数据库,所以外面知道密码也连不上,短时间内尽快更换密码就是了
虚拟空间要做好一些相关的处理事项,例如更多容错、一键闭站等等

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.
