"基于PHP的C语言网络课程设计与实现研究"

requires teachers and students to agree on time and location in advance, which to some extent restricts educators and learners. When face-to-face teaching is not convenient, online courses become particularly important. This system takes C language programming content as the carrier, combined with PHP and MySQL database technology, and implements a relatively complete online learning website. Using PHP technology for front-end interface design and MySQL for backend database design, the system interface is user-friendly and easy to operate. This website implements the functions commonly found in learning websites, such as user registration, login, online student answering questions, teacher posting and modifying questions, and administrator managing members and website content. Through this website, students can not only learn freely but also communicate with teachers through messages. Additionally, the system also includes features such as Flash demonstrations and video explanations. Through testing, this website runs stably and reliably, with certain practical value.
