php项目统计伤病停赛影响数据对比？

系统架构设计
高级功能扩展建议

我来帮你设计一个PHP项目统计伤病停赛影响数据对比的系统,这个系统可以帮助分析伤病对球队成绩的影响。

系统架构设计

数据库表结构

-- 球员表
CREATE TABLE players (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(100) NOT NULL,
    position VARCHAR(50),
    team_id INT,
    status ENUM('active', 'injured', 'suspended') DEFAULT 'active',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
-- 伤病记录表
CREATE TABLE injuries (
    id INT PRIMARY KEY AUTO_INCREMENT,
    player_id INT,
    injury_type VARCHAR(100),
    injury_date DATE,
    recovery_date DATE,
    severity ENUM('minor', 'moderate', 'severe'),
    matches_missed INT DEFAULT 0,
    description TEXT,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    FOREIGN KEY (player_id) REFERENCES players(id)
);
-- 比赛数据表
CREATE TABLE matches (
    id INT PRIMARY KEY AUTO_INCREMENT,
    match_date DATE,
    team_id INT,
    opponent_id INT,
    goals_for INT,
    goals_against INT,
    result ENUM('win', 'draw', 'loss'),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
-- 球队表
CREATE TABLE teams (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(100),
    league VARCHAR(50),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

使用示例

<?php
// 使用示例
require_once 'config/database.php';
require_once 'controller/InjuryController.php';
require_once 'InjuryImpactAnalyzer.php';
$db = new mysqli('localhost', 'username', 'password', 'football_db');
$controller = new InjuryController($db);
// 获取对比数据
$teamId = 1; // 球队ID
$viewData = $controller->compareAction($teamId);
// 加载视图
extract($viewData);
include 'views/injury_comparison.php';
?>

高级功能扩展建议

可视化图表

使用 Chart.js 或 ECharts 生成折线图、柱状图
展示伤病趋势和成绩变化

预测分析

基于历史数据预测未来伤病影响
使用线性回归或机器学习算法

位置价值分析

public function getPositionValueAnalysis($teamId) {
    // 分析不同位置球员伤病对成绩的影响权重
    // 前锋受伤影响得分
    // 后卫受伤影响失球
}

赛程密度分析

public function analyzeScheduleLoad($teamId, $seasonStart, $seasonEnd) {
    // 分析密集赛程期间的伤病频率
}

这个系统可以帮助球队管理层和教练组更好地理解伤病对球队成绩的影响,从而做出更科学的轮换决策和转会策略。
