如何在php中按字母键顺序对数组数据排序

$fruits = array("banana", "apple", "orange", "grape");
sort($fruits);

foreach ($fruits as $fruit) {
    echo $fruit . " ";
}

apple banana grape orange

$students = array(
    array("name" => "John", "age" => 20),
    array("name" => "Alice", "age" => 18),
    array("name" => "Bob", "age" => 22)
);

// 获取学生姓名列的列表
foreach ($students as $key => $row) {
    $names[$key] = $row['name'];
}

// 按字母键顺序对学生姓名进行排序
array_multisort($names, SORT_ASC, $students);

// 输出排序后的学生姓名和年龄
foreach ($students as $student) {
    echo $student['name'] . " - " . $student['age'] . "<br>";
}

Alice - 18
Bob - 22
John - 20
