PHP8中调换数组中的键值和元素值-PHP8知识详解

<?php
    $stu =array("子涵"=> 001,"欣怡"=> 002,"梓涵"=>003,"晨曦"=> 004);
    $newstu = array_flip($stu);
    echo "原始数组为：<br />";
	echo "<pre>"; 
    print_r($stu);
    echo "<br />调换后的数组为：<br />";
	echo "<pre>"; 
    print_r($newstu)
?>

原始数组为：
Array
(
    [子涵] => 1
    [欣怡] => 2
    [梓涵] => 3
    [晨曦] => 4
)

调换后的数组为：
Array
(
    [1] => 子涵
    [2] => 欣怡
    [3] => 梓涵
    [4] => 晨曦
)
