实时php项目显示场上谁更占优势？

wen PHP项目 227

我可以帮您设计一个实时PHP项目来显示比赛双方的占优情况,这需要前端实时通信（如WebSocket或轮询）和后端计算逻辑的结合。

实时php项目显示场上谁更占优势？

完整解决方案

数据库设计（MySQL）

CREATE TABLE matches (
    id INT PRIMARY KEY AUTO_INCREMENT,
    match_name VARCHAR(100),
    status ENUM('live', 'paused', 'ended') DEFAULT 'live',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
CREATE TABLE team_stats (
    id INT PRIMARY KEY AUTO_INCREMENT,
    match_id INT,
    team_name VARCHAR(50),
    score INT DEFAULT 0,
    possession FLOAT DEFAULT 50.0,  -- 控球率
    shots INT DEFAULT 0,           -- 射门次数
    shots_on_target INT DEFAULT 0, -- 射正次数
    corners INT DEFAULT 0,
    fouls INT DEFAULT 0,
    passes INT DEFAULT 0,
    pass_accuracy FLOAT DEFAULT 0, -- 传球成功率
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    FOREIGN KEY (match_id) REFERENCES matches(id)
);
CREATE TABLE match_events (
    id INT PRIMARY KEY AUTO_INCREMENT,
    match_id INT,
    team_name VARCHAR(50),
    event_type ENUM('goal', 'shot', 'corner', 'foul', 'card'),
    minute INT,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

优势计算逻辑（PHP类）

<?php
// AdvantageCalculator.php
class AdvantageCalculator {
    private $db;
    public function __construct($pdo) {
        $this->db = $pdo;

        if (!$stats || count($stats) < 2) {
            return ['team_a' => 50, 'team_b' => 50, 'details' => []];
        }
        $teamA = $stats[0];
        $teamB = $stats[1];
        // 各维度权重
        $weights = [
            'score' => 0.25,          // 比分权重
            'possession' => 0.20,     // 控球率

            'corners' => 0.10,        // 角球
            'pass_accuracy' => 0.10   // 传球成功率

        $scores['corners'] = $totalCorners > 0 ? 
            ($teamA['corners'] / $totalCorners) * 100 : 50;
        // 传球成功率
        $scores['pass_accuracy'] = $this->calculatePassAdvantage(

                'weights' => $weights
            ]
        ];
    }
    private function calculatePassAdvantage($accA, $accB) {
        // 将传球成功率转换为相对优势
        $diff = $accA - $accB;
        $advantage = 50 + ($diff * 5); // 每5%差距 = 25分差距
        return max(0, min(100, $advantage));
    }
    private function getTeamStats($matchId) {
