// Read the database data, convert the data format after reading the data, and configure the highchart data source. Anyway, finally opened, haha!

Database Connection: conn_orcale.php

<? Php $ dbconn = oci_connect ("dnc-local", "dnc-local", "orcl") or die ("database connection error");?>

Read data: 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);?>

Or

<?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);?>

<?php  require 'device_query.php';?>
Positive energy, with images and truth.
