需要把数据库数据与echart连接起来,但是echart需要json格式,所以想用php把数据库中数据转化为json格式,然后再在echart里调用。现在做到了这一步,希望大家帮忙看看,越详细越好,如果有其他方法也可以,因为需要转换的数据量很大
<?php header("Content-type: text/html; charset=utf-8"); $host='127.0.0.1'; $user='root'; $password=''; $database='mydatabase'; $con=mysqli_connect($host,$user,$password,$database); //mysqli_query($con,"set names utf8"); $ss = "SELECT * FROM passenger"; $result = mysqli_query($con,$ss); if (mysql_num_rows($result) > 0) { // 输出每行数据 while($row = mysql_fetch_assoc($result)) { echo "<br> WIFIAPTag: ". $row["WIFIAPTag"]. " passengerCount: ". $row["passengerCount"]. " timeStamp:" . $row["timeStamp"]; } } else { echo "0 个结果"; } mysqli_close($con); ?>
