PHP循环通过JSON多维数组并在按钮单击时加载数据

Question

Basically I'm retrieving a JSON content from a php call using some custom API. The arrays are all social posts. The code I'm using at the moment displays all of them at once when the page is loaded. I Would like to show them 10 or 20 at time, depending on my need, I'm using a PHP foreach loop to put the data on the page. I would like to get the first 10 indexes (from [0] to [10]) and setup a button to load the next indexes [11], [12], [13]..., let's say 10 at time( from [11] to [20], from [21] to [30] ) at each click. Is this possible?

The JSON content looks like this:

 Array

  (

    [comments] => Array

      (

        [0] => Array

          (

             [type] => instagram

             [author] => Rick B.

             [message] =>

<?php

function doMyStuff()
{
    // Doing all your other stuff in here.. 
    $currentIndex = 30;
    getData($currentIndex);
}    

function getData(currentIndex) {
    $maxIndex = currentIndex + 10;
    for($x = $currentIndex; $x < maxIndex; $x++) {
        echo '<div class="'. $comment['content{$x}'] .'"><p>Content..'..'</p></div>';
    }

}

This may or may not be what you are looking for, but basically.. pass the getData function with the current index of the array, say 30 - getData(30); then the function will echo the next 10 contents based on the current index and the max index being 10 more than the current.

['content{$x}'] is a neat little way of directly inserting a variable / object into a string.
