使用Highcharts生成折线图_at last

//数据库数据的读取,读取数据后数据格式的转换,还有highchart数据源的配置,伤透了脑筋。anyway,终于开张了,哈哈!

数据库连接:conn_orcale.php

<?php
$dbconn=oci_connect("dnc-local","dnc-local","orcl")or die("数据库连接错误");
?>
读取数据: device_query.php

<?php
  require 'conn_orcale.php';
  $sql = "select * from xiaolv_month";
  $query = oci_parse($dbconn,$sql);
  oci_execute($query);
   <span style="color:#ff0000;">while( $a = oci_fetch_array($query))
   {
   	
   	$b[] = intval($a[1]);
  
   }
    $data= json_encode($b);</span>
     oci_close($dbconn);
?>

<?php
  require 'conn_orcale.php';
  $sql = "select month,xiaolv from xiaolv_month";
  $query = oci_parse($dbconn,$sql);
  <span style="color:#ff0000;">$b=array();
   while( $a = oci_fetch_array($query))
   {
   	array_push($b,intval($a[1]));
   }
    echo json_encode($b);</span>
     oci_close($dbconn);
?>
