1:下载
curl -sS https://getcomposer.org/installer | php
或者
php -r "readfile('https://getcomposer.org/installer');" | php
2:移动到bin目录下,以后每次使用直接使用composer命令
mv composer.phar /usr/local/bin/composer
查看版本
composer -V
3.composer.json 在项目中安装monolog
composer.json文件内容如下
{ "require": { "monolog/monolog": "1.0.*" }}
使用composer install 安装,在当前目录下回创建vendor/monolog/monolog 目录
Composer 生成了一个 vendor/autoload.php 文件。你可以简单的引入这个文件,你会得到一个免费的自动加载支持。
这使得你可以很容易的使用第三方代码。项目依赖 monolog,你就可以像这样开始使用这个类库,并且他们将被自动加载。
$log = new Monolog\Logger('name');$log->pushHandler(new Monolog\Handler\StreamHandler('app.log', Monolog\Logger::WARNING));$log->addWarning('Foo');
4:下载thinkphp框架并安装monolog
composer create-project topthink/thinkphp myProjectNamecd myProjectNamevim composer.json
找到require
修改为:
"require": { "php": ">=5.3.0", "monolog/monolog": "1.0.*" }, 找到http://packagist.phpcomposer.com改为https://packagist.phpcomposer.com
保存退出
composer install
当前目录会
在当前目录下回创建vendor/monolog/monolog 目录
可在框架入口文件中引入 vendor/autoload.php
就可在框架中使用了
5.获取依赖的最新版本
composer update
如果你只是想更新几个包
composer update vendor/package vendor/package2
用通配符进行批量更新
composer update vendor/*

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),
