为什么要用 yaml
因为 Yaml 简单,而且对人类友好;
Yaml: http://www.yaml.org/
在哪里会用到?
最基本的,在 ThinkPHP 的配置文件里面就可以选择 Yaml 的格式,你是愿意写 Yaml 的简洁格式配置呢?还是愿意写又长又臭又难写的 PHP array 呢?
http://document.thinkphp.cn/manual_3_2.html#config_format
问题来了
于是,我把配置格式改为 Yaml:
代码如下:
// /index.php
// 定义配置文件的格式为 yaml
define('CONF_EXT', '.yaml');
然后把 Application 目录下面的 config.php 全部改为 config.yaml。
这个时候,报错:
代码如下:
Class ‘Spyc' not found 错误位置 FILE: D:\app\think\ThinkPHP\Common\functions.php LINE: 90
然后找,发现这一段:
代码如下:
/**
* 解析yaml文件返回一个数组
* @param string $file 配置文件名
* @return array
*/
if (!function_exists('yaml_parse_file')) {
function yaml_parse_file($file) {
vendor('spyc.Spyc');
return Spyc::YAMLLoad($file);
}
}
貌似引入 Spyc 这个库没找到。
找了一下,Spyc 在这里:https://github.com/mustangostang/spyc/
然后,这个 vendor 是什么东东?
看这里:http://document.thinkphp.cn/manual_3_2.html#autoload
结论:
在上面的 Git 里面下载 Spyc.php 放进 /ThinkPHP/Library/Vendor/spyc/ 目录下,就一切正常!Done with the right way!

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.
