根据php项目，客队客场表现如何评估？

注意事项

在PHP项目中评估客队客场表现,通常需要结合数据采集、指标计算和可视化展示，下面从评估维度、PHP实现思路、代码示例三个方面说明。

评估维度

客队客场表现可从以下指标综合评估：

维度	指标	说明
战绩	客胜率、客平率、客负率	客场胜平负占比
进攻	场均客场进球	客场进球数/客场场次
防守	场均客场失球	客场失球数/客场场次
净胜球	客场净胜球	进球-失球
稳定性	客场连续不败/连败场次	状态波动
对手强度	对手平均排名	加权修正
主客场差异	客场表现 vs 主场表现	差异系数

PHP实现思路

数据表设计（MySQL）

CREATE TABLE matches (
    id INT PRIMARY KEY AUTO_INCREMENT,
    home_team_id INT,
    away_team_id INT,
    home_goals TINYINT,
    away_goals TINYINT,
    match_date DATE,
    league_id INT
);

核心计算类

class AwayPerformanceEvaluator
{
    private PDO $pdo;
    public function __construct(PDO $pdo)
    {
        $this->pdo = $pdo;
    }
    /**
     * 获取客队客场统计数据
     */
    public function getAwayStats(int $teamId, int $limit = 10): array
    {
        $sql = "SELECT 
                    COUNT(*) AS played,
                    SUM(CASE WHEN away_goals > home_goals THEN 1 ELSE 0 END) AS wins,
                    SUM(CASE WHEN away_goals = home_goals THEN 1 ELSE 0 END) AS draws,
                    SUM(CASE WHEN away_goals < home_goals THEN 1 ELSE 0 END) AS losses,
                    SUM(away_goals) AS goals_for,
                    SUM(home_goals) AS goals_against,
                    AVG(away_goals) AS avg_goals_for,
                    AVG(home_goals) AS avg_goals_against
                FROM (
                    SELECT * FROM matches 
                    WHERE away_team_id = :team_id
                    ORDER BY match_date DESC
                    LIMIT :limit
                ) AS recent";
        $stmt = $this->pdo->prepare($sql);
        $stmt->bindValue(':team_id', $teamId, PDO::PARAM_INT);
        $stmt->bindValue(':limit', $limit, PDO::PARAM_INT);
        $stmt->execute();
        return $stmt->fetch(PDO::FETCH_ASSOC) ?: [];
    }
    /**
     * 计算综合客场评分（0-100）
     */
    public function calculateAwayScore(int $teamId): array
    {
        $stats = $this->getAwayStats($teamId);
        if (empty($stats) || $stats['played'] == 0) {
            return ['score' => 0, 'detail' => $stats];
        }
        $played = (int)$stats['played'];
        $winRate = $stats['wins'] / $played;
        // 胜率得分（40%权重）
        $winScore = $winRate * 100 * 0.4;
        // 进攻得分（30%权重，场均进球/3 封顶）
        $attackScore = min($stats['avg_goals_for'] / 3, 1) * 100 * 0.3;
        // 防守得分（30%权重，场均失球越少越高）
        $defenseScore = max(0, 1 - $stats['avg_goals_against'] / 3) * 100 * 0.3;
        $total = round($winScore + $attackScore + $defenseScore, 2);
        return [
            'score' => $total,
            'win_rate' => round($winRate * 100, 2) . '%',
            'avg_goals_for' => round($stats['avg_goals_for'], 2),
            'avg_goals_against' => round($stats['avg_goals_against'], 2),
            'detail' => $stats,
        ];
    }
}

使用示例

$pdo = new PDO('mysql:host=localhost;dbname=football', 'user', 'pass');
$evaluator = new AwayPerformanceEvaluator($pdo);
$result = $evaluator->calculateAwayScore(123);
echo "客场综合评分: {$result['score']}\n";
echo "客胜率: {$result['win_rate']}\n";
echo "场均客场进球: {$result['avg_goals_for']}\n";
echo "场均客场失球: {$result['avg_goals_against']}\n";
