Summary of mathematics teaching work in second grade of primary school Summary of 20 commonly used PHP class libraries

Chart Library

The following class library allows you to easily create complex charts and pictures. Of course, they require support from the GD library.

• pChart - A library for creating statistical charts.
• Libchart - This is also a simple statistical gallery.
• JpGraph - An object-oriented image creation class.
• Open Flash Chart - This is a Flash-based statistical chart.

RSS parsing

• MagpieRSS - an open source PHP version of the RSS parser, said to be powerful but not verified.
• SimplePie - This is a very fast and easy-to-use RSS and Atom parsing library.

Thumbnail generation

• phpThumb - The function is very powerful, you have to experience it yourself.

Payment

• PHP Payment Library - Supports Paypal, Authorize.net and 2Checkout (2CO)

OpenID

• PHP-OpenID - A PHP library that supports OpenID. OpenID is a solution that helps you log into different websites using the same username and password. If you are not familiar with OpenID, you can take a look here: http://openid.net.cn/

Data is abstraction/object relational mapping ORM

• ADOdb - database abstraction
• Doctrine - Object relational mapper (ORM), requires PHP 5.2.3+ version, a very powerful database abstraction layer (DBAL).
• Propel - Object Relational Mapping Framework - PHP5
• Outlet - is also a tool for object-relational mapping.

Note: Object Relational Mapping (ORM) is a technology designed to solve the mismatch between object-oriented and relational databases. Simply put, ORM automatically persists objects in a program into a relational database by using metadata that describes the mapping between objects and databases. Essentially, it converts data from one form to another. This also implies additional execution overhead; however, if the ORM is implemented as a middleware, there are many opportunities for optimizations that do not exist in a hand-written persistence layer. More importantly, the metadata used to control transformations needs to be provided and managed; but again, these costs are less than maintaining a handwritten solution; and even ODMG-compliant object databases still require class-level metadata.

PDF Generator

• FPDF - This is a pure PHP library that allows you to generate PDF.

Excel related

• php-excel - This is a very simple Excel file generation class.
• PHP Excel Reader - can parse and read data in XLS files.

E-Mail related

• Swift Mailer - Free super versatile PHP email library.
• PHPMailer - Super powerful email sending class.

Unit Testing

If you are using a test-driven approach to develop your program, the following class libraries and frameworks will definitely help you in your development.

• SimpleTest - A PHP unit testing and web page testing framework.
• PHPUnit - From the xUnit family, it provides a framework that allows you to easily carry out unit test case development. And its test results can be analyzed very easily.

The above introduces the summary of the mathematics teaching work of the second grade of primary school and the summary of 20 commonly used PHP class libraries, including the summary of the mathematics teaching work of the second grade of primary school. I hope it will be helpful to friends who are interested in PHP tutorials.
