PHP Online Judge System Abstract
ACM / ICPC (ACM International Collegiate ProgrammingContest, International Collegiate Programming Contest) is a long history and quite authoritative organization ACM (Association for Computing Machinery International Computer Association) sponsored, recognized as the world's largest and highest level of international Collegiate Programming Contest, which aims to help college students improve the use of computer analysis of issues and problem-solving abilities of the
ACM Online Assessment System is a transaction processing platform, the contest judge, is based on B / S structure of the multi-user online system that allows users to problem solving and their code submitted online, the system automatically compiles and runs the referee gives the results of problem solving based on the number of users and the use of rank when discharged.
System architecture using the current Internet, the popular Web site architecture approach: LAMP (Linux + Apache + MySQL + PHP), that the use of Linux as a server operating system, Apache as the Web server, MySQL as a database, PHP as server-side script interpreter . ZHBIT ACM Online Judge System development environment is set up under Ubuntu Linux Web server, Apache, MySQL as the database server simultaneously, PHP as server-side script interpreter, the integrated use of this platform PHP, C language, html, database technology for system development. Since this software is to follow the four open source GPL software, so do not spend a penny to use this approach can establish a stable, free web site system. That when built up after the system put into use immediately, without regard to copyright or other issues.原文请+QQ3249,114辣.文^论,文'网h
