Question

我从数据库中获取数据。成功执行查询后，结果如下。对于每个BRANCH，有4个值。

    <?php
     $data = 
    '{"8":{"SDATE":"01-APR-2013","BRANCH":"MEDICAL","FEES":"16000","PER_INC":".68","CLG_RANK":"7"},
     "9":{"SDATE":"01-AUG-2012","BRANCH":"MEDICAL","FEES":"14000","PER_INC":".047","CLG_RANK":"6"},
     "10":{"SDATE":"01-DEC-2012","BRANCH":"MEDICAL","FEES":"15500","PER_INC":".87","CLG_RANK":"7"},
     "11":{"SDATE":"01-FEB-2013","BRANCH":"MEDICAL","FEES":"17500","PER_INC":".72","CLG_RANK":"7"},
     "12":{"SDATE":"01-JAN-2013","BRANCH":"ELECTRICAL","FEES":"12200","PER_INC":".18","CLG_RANK":"7"},
     "13":{"SDATE":"01-JUL-2012","BRANCH":"ELECTRICAL","FEES":"17000","PER_INC":".071","CLG_RANK":"6"},
     "14":{"SDATE":"01-JUL-2013","BRANCH":"ELECTRICAL","FEES":"15700","PER_INC":".044","CLG_RANK":"8"},
     "15":{"SDATE":"01-JUN-2013","BRANCH":"ELECTRICAL","FEES":"13000","PER_INC":".78","CLG_RANK":"8"},
     "16":{"SDATE":"01-MAR-2013","BRANCH":"MECHANICAL","FEES":"13200","PER_INC":".95","CLG_RANK":"7"},
     "17":{"SDATE":"01-MAY-2013","BRANCH":"MECHANICAL","FEES":"16000","PER_INC":".27","CLG_RANK":"8"},
     "18":{"SDATE":"01-NOV-2012","BRANCH":"MECHANICAL","FEES":"14000","PER_INC":".82","CLG_RANK":"7"},
     "19":{"SDATE":"01-OCT-2012","BRANCH":"MECHANICAL","FEES":"17500","PER_INC":".32","CLG_RANK":"7"},
     "20":{"SDATE":"01-SEP-2012","BRANCH":"CIVIL","FEES":"13500","PER_INC":".67","CLG_RANK":"6"},
     "21":{"SDATE":"01-APR-2013","BRANCH":"CIVIL","FEES":"14700","PER_INC":".56","CLG_RANK":"8"},
     "22":{"SDATE":"01-AUG-2012","BRANCH":"CIVIL","FEES":"18000","PER_INC":"0","CLG_RANK":"7"},
     "23":{"SDATE":"01-DEC-2012","BRANCH":"CIVIL","FEES":"15000","PER_INC":"0","CLG_RANK":"8"}}';
      ?>

我必须将数据转换为数组并将数组值传递给图形。请查看此图http://www.highcharts.com/demo/area-stacked。 x轴值必须是SDATE值，即日期。 y轴值必须为FEES。在我发布的链接中，可以在图表中和x轴下方看到的国家/地区将替换为BRANCH的值。

    $(function () {
       var data = new Array();
       data = '<?php echo $data; ?>'; 
       // code to be written
     });

总结是我在上面的URL中提到的图表将被BRANCH的$ data值替换，即基于分支x轴和y轴值是显示。

我该怎么办？请任何人帮忙。我试了一整天。但由于我不擅长数组，我无法做到这一点。 Atleast告诉如何根据BRANCH值

将值转换为数组

通常问题是它不是JSON /正确的字符串。所以在开始时我建议你注意你的格式然后结构。它应该是系列和数据的数组。字段应使用highcharts标准正确命名，而不是自定义名称。日期必须是时间戳。在SO，有许多类似的主题。
