本文目录导读：
我来为您设计一个PHP项目,用于统计和分析球队伤病停赛对比赛成绩的影响数据对比。
数据库设计
-- 球员表

);
-- 球队表
CREATE TABLE teams (

-- 比赛记录表
CREATE TABLE matches (

这个完整的PHP项目提供了：
- 数据库设计：支持球员、球队、比赛、缺席记录的完整数据模型
- 核心分析功能：多维度统计对比（按缺席人数、位置、球员重要性等）
- 高级对比分析：赛前后对比、主客场对比、受伤vs停赛对比
- 可视化展示：使用Chart.js展示统计图表
- 预测功能：预测伤病对下一场比赛的影响
- 数据导出：支持Excel和PDF格式导出
您可以根据实际需求调整统计维度和展示方式,需要我详细解释某个部分的具体实现吗？
