在PHP中根据计数和百分比选择候选人

$candidates = [
    ['name' => 'Candidate A', 'votes' => 100],
    ['name' => 'Candidate B', 'votes' => 200],
    ['name' => 'Candidate C', 'votes' => 150],
    // 添加更多候选人信息
];

function selectCandidate($count, $percentageThreshold) {
    global $candidates;
    
    // 根据得票数排序候选人数组
    usort($candidates, function($a, $b) {
        return $b['votes'] - $a['votes'];
    });
    
    // 计算总得票数
    $totalVotes = array_sum(array_column($candidates, 'votes'));
    
    // 计算百分比阈值对应的得票数
    $thresholdVotes = $totalVotes * $percentageThreshold / 100;
    
    // 选择候选人
    $selectedCandidates = [];
    $selectedVotes = 0;
    foreach ($candidates as $candidate) {
        $selectedCandidates[] = $candidate['name'];
        $selectedVotes += $candidate['votes'];
        
        // 判断是否达到计数和百分比要求
        if (count($selectedCandidates) >= $count || $selectedVotes >= $thresholdVotes) {
            break;
        }
    }
    
    return $selectedCandidates;
}

$selectedCandidates = selectCandidate(2, 50); // 选择2个候选人，百分比阈值为50%
print_r($selectedCandidates);
