以下是一个简单的PHP评委计分系统的实现，该系统允许评委为参赛者打分，并计算总分。
```php
// 初始化评委分数数组
$scores = [
'评委1' => 0,
'评委2' => 0,
'评委3' => 0,
'评委4' => 0,
'评委5' => 0
];
// 假设这是参赛者的分数
$contestant_scores = [
'参赛者A' => [
'评委1' => 10,
'评委2' => 9,
'评委3' => 8,
'评委4' => 7,
'评委5' => 6
],
'参赛者B' => [
'评委1' => 8,
'评委2' => 9,
'评委3' => 10,
'评委4' => 7,
'评委5' => 8
],
'参赛者C' => [
'评委1' => 6,
'评委2' => 7,
'评委3' => 8,
'评委4' => 9,
'评委5' => 10
]
];
// 更新评委分数
foreach ($contestant_scores as $contestant => $score) {
foreach ($score as $judge => $score_value) {
$scores[$judge] += $score_value;
}
}
// 计算平均分
foreach ($scores as $judge => $total_score) {
$scores[$judge] = $total_score / count($contestant_scores);
}
// 打印评委分数表格
echo "
