注释一下这些代码$students = name = Lily Lucy Tom Jim sex = female female male male;for $i = 0; $i count$studentsname; $i++ echo $studentsname$i is $studentssex$i PHP_EOL;

// 定义一个关联数组，包含姓名和性别两个键，每个键对应一个数组 $students = ['name' => ['Lily', 'Lucy', 'Tom', 'Jim'], 'sex' => ['female', 'female', 'male', 'male']];

// 循环遍历学生姓名数组，直到数组末尾 for ($i = 0; $i < count($students['name']); $i++) { // 输出每个学生的姓名和性别 echo $students['name'][$i] . ' is ' . $students['sex'][$i] . PHP_EOL; }
