Last active May 11, 2023 05:09
Leetcode: php 給一個陣列，裡面每個值代表容器兩旁的高度，要計算使用哪兩個高度，可以取得最大面積，並且顯示面積結果。
<?php
function maxArea($height) {
$result = 0;
// 第一個高度的位置
for ($i = 0; $i < sizeof($height); $i++) {
// 第二個高度的位置
for ($j = 1; $j < sizeof($height); $j++) {
// 相同高度不用和自己比較
if ($i === $j) {
continue;

* 至後台建立選單，並勾選 Mega menu，自訂的 Walker 會將第二層選項建成 .row .col 的形式
* 第二層選單的 css class 設為 mega-col，會自動註冊對應的「小工具容器」 (widget sidebar)
* 就能以小工具形式自訂 mega menu 的欄位內容。
