PhpIniDir的应用 php源程序中 php.ini-dist和php.ini-recommended的区别
PhpIniDir的应用(转载)
PhpIniDir是PHP的初始化文件php.ini的路径,过去大家将php.ini放在windows目录下,在PHP5中,PHP.ini的查找路径不再限于PHP4时代的%SystemRoot%,PHP5会按以下顺序查找PHP.ini:
1、PHPIniDir(Apache 2 module only,这个指令仅仅用于当PHP作为Apache模块时使用,不支持CGI运行的PHP)
2、注册表键值:HKEY_LOCAL_MACHINE/SOFTWARE/PHP/IniFilePath
3、环境变量:%PHPRC%
4、PHP5的目录(for CLI),或者web服务器目录(for SAPI modules)
5、Windows目录(C:/windows or C:/winnt)
这五个方案中,配合Apache2时最好使用PHPIniDir,即在apache2/conf/httpd.conf文件中加入:
# configure the path to php.ini
PHPIniDir " C:/php"
另外,NTFS上记得给服务器开PHP.ini的读权限。

附:php.ini-dist与php.ini-recommended的区别
根据php.ini-dist的说明,二者不同之处在于php.ini-dist适合开发程序使用,而php.ini-recommended 拥有较高的安全性设定,适合上线当产品使用。因此,出于安全和效率的考虑,建议使用php.ini-recommended作为php.ini的蓝本,而 不要使用php.ini-dist。
官方说明如下:
This is the default settings file for new PHP installations.By default, PHP installs itself with a configuration suitable for development purposes, and *NOT* for production purposes.For several security-oriented considerations that should be taken before going online with your site, please consult php.ini-recommended and http://php.net/manual/en/security.php.

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),
