This article mainly introduces the implementation code of PHP using Echarts to generate data statistical reports. Friends who need it can refer to it. I hope it can help everyone.

echarts statistics, simple example

Look at the renderings first

##Look at the code

HTML page is ECharts Prepare a Dom, custom width and height

<p class="panel panel-info">
　　<p class="panel-body">
　　　　<p id="echart_show" style="height:500px"></p>
　　</p>
</p>

js file can refer to the official website, or download it here, introduce

The following is the specific method

<script type="text/javascript">

  var date = [],num = [];
  $(document).ready(function () {
    // 绘制反馈量图形
    var init_echarts = function () {
      var refreshChart = function (show_data) {
        my_demo_chart = echarts.init(document.getElementById(&#39;echart_show&#39;));

        my_demo_chart.showLoading({
          text: &#39;加载中...&#39;,
          effect: &#39;whirling&#39;

        };
        my_demo_chart.hideLoading();
        my_demo_chart.setOption(echarts_all_option);
      };

      // 获取原始数据
      $.ajax({
        url:"__CONTROLLER__/getRes",
        async:false,
        dataType:&#39;json&#39;,
        type:&#39;post&#39;,

        success:function(msg){
          var result = msg.result;
          if(msg.code == 200){
            for(var i = 0 ; i < result.length; i++){
              date.push(result[i].date);
              num.push(result[i].count);
              msg[0] = num;
              msg[1] = date;
              refreshChart(msg);
            }
          }
        }
      });
    };

    // 默认加载
    var default_load = (function () {
      init_echarts();
    })();
  });


</script>

Query the data you need in the controller (the date queried here and the corresponding quantity)

//折线统计
  public function getRes(){
    $user = M('account');
    $sql = "SELECT date(createTime) AS date,count(*) as count FROM t_account GROUP BY date ";
    $result = $user->query($sql);
    $this->ajaxReturn(array('code'=>200,'result'=>$result));
  }

At this point, a simple echarts statistical chart has come out
