php A binary array is sorted by a value of a subarray
PHP： Sort according to a field in the two-dimensional array - Shenwenzhe - Blog Garden Let's first look at the following two functions ： 1.array_column() Returns the value of a single column in the input array . 2.array_multisort() Function returns a sorted array . You can enter one or more arrays . Function first arranges the first array https://www.cnblogs.com/wenzheshen/p/9455554.html

PHP Dynamic templates ob_start Nested variables ,foreach etc.

I changed the code , Look at the core js that will do （HTML Refer to the above “PHP Dynamic templates ob_start Nested variables ,foreach etc. ”）

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

// After the page is loaded, load the waterfall flow 
window.onload = function(){
    loadWaterfall('waterPool','waterBox');
}

// Load waterfall stream function 
function loadWaterfall(boxID,thumbnailClass){
    // Get the box outside the thumbnail 
    var box = document.getElementById(boxID);
    // Get the array of thumbnails 
    var thumbnail = box.getElementsByClassName(thumbnailClass);
    // Several thumbnails can be arranged in each row of the calculation box 
    var colCount = 3;
    // Create an array of heights to put each time 
    var thumbnailHeightArr = [];

    var spaceHeightBetween = 30; // px


    // console.log(thumbnail.length);


    for(var i = 0; i < thumbnail.length; i++){
        // console.log(i);
        // Get the first row height array 
        if(i < colCount){
            thumbnailHeightArr.push(thumbnail[i].clientHeight);
            // thumbnailHeightArr.push(thumbnail[i].offsetHeight);
            // console.log(JSON.stringify(thumbnailHeightArr));

        }else{
            // Get the previous minimum height 
            var minHeight = Math.min.apply(null,thumbnailHeightArr);
            // console.log(JSON.stringify('Min height: '+minHeight));

            // First row minimum height index 
            var minIndex = thumbnailHeightArr.indexOf(minHeight);
            // console.log(JSON.stringify('Min index: '+minIndex));

            // Place this thumbnail below the minimum height of the line above 
            thumbnail[i].style.position = 'absolute';
            // The length from the top is the length of the thumbnail above this thumbnail 
            let curHeightBegin = spaceHeightBetween + minHeight;
            thumbnail[i].style.top = curHeightBegin + 'px';

            // The length from the left is the length from the left of the thumbnail above this thumbnail 
            thumbnail[i].style.left = thumbnail[minIndex].offsetLeft + 'px';

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

            // Update minimum height 
            thumbnailHeightArr[minIndex] += thumbnail[i].offsetHeight;

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

    let currentMinHeight = Math.max.apply(null,thumbnailHeightArr) + 150;
