红色荷包蛋 2023-06-19 11:25关注答案参考ChapGPT Plus . 希望对你有帮助根据您提供的数组，每个学生的在自己学校所在排名可以通过以下方式计算：
首先，您需要按学校和总分对数组进行分组和排序，以获得每个学校按总分排好序的学生列表。
接下来，您可以遍历每个学生，在其所属学校的学生列表中查找其自己的排名。
以下是一个示例的PHP代码，展示了如何实现上述步骤：
// 原始数组 $students = array( array( 'id' => 72, 'name' => '学生LL', 'school' => '云校', 'zongfen' => 330, ), array( 'id' => 49, 'name' => '学生A', 'school' => '云校', 'zongfen' => 300, ), array( 'id' => 50, 'name' => '学生B', 'school' => '云校', 'zongfen' => 295, ), // 其他学生... ); // 按学校和总分排序 usort($students, function ($a, $b) { if ($a['school'] !== $b['school']) { return strcmp($a['school'], $b['school']); } return $b['zongfen'] - $a['zongfen']; }); // 计算每个学生在自己学校所在排名 $rankings = array(); $currentRank = 1; $currentSchool = $students[0]['school']; foreach ($students as $student) { if ($student['school'] !== $currentSchool) { $currentRank = 1; $currentSchool = $student['school']; } $rankings[$student['id']] = $currentRank; $currentRank++; } // 输出每个学生的在自己学校所在排名 foreach ($rankings as $studentId => $rank) { echo "学生ID: $studentId, 学校内排名: $rank\n"; }请注意，上述代码仅展示了计算每个学生在自己学校所在排名的基本逻辑，并假设了已知的数组结构。您可以根据实际情况进行适当的调整和修改。
