php 二位数组按子数组某值排序
PHP：根据二维数组中的某个字段进行排序 - 申文哲 - 博客园首先了解下以下两个函数： 1.array_column() 返回输入数组中某个单一列的值。 2.array_multisort() 函数返回排序数组。您可以输入一个或多个数组。函数先对第一个数组进行排https://www.cnblogs.com/wenzheshen/p/9455554.html

PHP动态模板 ob_start 嵌套变量，foreach等

/**
 * component_tpl
 * 
 */
function component_tpl ($cName, $data = array()) 
    $return = '';
    $path = PATH_COMPONENTS . $cName . '.php';

    ob_start();
    $tpl_data = $data;
    require $path;
    $return = ob_get_contents();
    ob_end_clean();

    return $return;



=====================  模板 =================


<div class="myWaterPool">
    <div class="row" id="waterPool">
        <?php foreach($tpl_data['apps'] as $k=>$v): ?>
            <div class="col-sm-3 col-sm-offset-1 waterBox">
                <a href="<?php echo $v['urlApp']; ?>" style="text-decoration: none; color: gray;">
                    <div>

                        <div class="text-center">
                            <?php echo $v['title']; ?>
                        </div>

瀑布流 （直接看最下面的js部分）

https://www.cnblogs.com/mazey/p/15647609.htmlhttps://www.cnblogs.com/mazey/p/15647609.html

我改过的代码，看核心js即可（HTML参考上面的“PHP动态模板 ob_start 嵌套变量，foreach等”）

// https://www.cnblogs.com/mazey/p/15647609.html

//页面加载完之后再加载瀑布流
window.onload = function()
    loadWaterfall('waterPool','waterBox');


//加载瀑布流函数
function loadWaterfall(boxID,thumbnailClass)
    //获取装缩略图外部的盒子
    var box = document.getElementById(boxID);
    //获取装缩略图的数组
    var thumbnail = box.getElementsByClassName(thumbnailClass);
    //计算盒子内每行可以排列几个缩略图
    var colCount = 3;
    //创建放每次整理好的高度数组
    var thumbnailHeightArr = [];

    var spaceHeightBetween = 30; // px


    // console.log(thumbnail.length);


    for(var i = 0; i < thumbnail.length; i++)
        // console.log(i);
        //获取第一行高度数组
        if(i < colCount)
            thumbnailHeightArr.push(thumbnail[i].clientHeight);
            // thumbnailHeightArr.push(thumbnail[i].offsetHeight);
            // console.log(JSON.stringify(thumbnailHeightArr));

        else
            //获取之前最小高度
            var minHeight = Math.min.apply(null,thumbnailHeightArr);
            // console.log(JSON.stringify('Min height: '+minHeight));

            //第一行最小高度索引
            var minIndex = thumbnailHeightArr.indexOf(minHeight);
            // console.log(JSON.stringify('Min index: '+minIndex));

            //将此缩略图放在上面那行最小高度下面
            thumbnail[i].style.position = 'absolute';
            //距离顶部长度为这个缩略图上面那个缩略图的长度
            let curHeightBegin = spaceHeightBetween + minHeight;
            thumbnail[i].style.top = curHeightBegin + 'px';

            //距离左边长度为这个缩略图上面那个缩略图距离左边的长度
            thumbnail[i].style.left = thumbnail[minIndex].offsetLeft + 'px';

            // col-sm-offset-1
            thumbnail[i].classList.remove('col-sm-offset-1');

            //更新最小高度
            thumbnailHeightArr[minIndex] += thumbnail[i].offsetHeight;

            // console.log(JSON.stringify(thumbnailHeightArr));
        
    

    /* 父dom高度塌陷 - https://blog.csdn.net/wangjun5159/article/details/102527004 */
    let currentMinHeight = Math.max.apply(null,thumbnailHeightArr) + 150;
    box.style.minHeight = currentMinHeight + 'px';
