近期处理多个Highcharts图标时，碰到重复操作，所以编写了一个流程控制器

HTML选择页面

 

第一部分：<?php

第一部分进入分流（例举其一）：
　　

<?php
/**

 * Date: 2018/9/4
 * Time: 9:50
 */
include('common/common.php');
    if(empty($_SESSION['data_num']) || "null" == $_SESSION['data_num']) {

        echo "<script>window.location.href='log_num.php?Pass=3;'</script>";
    } else {
        $data = $_SESSION['data_num'];;
    }
include('tpl/chart_pie_num.html');
