在Highcharts中使用JavaScript中的PHP变量

Question

可能重复:
将PHP字符串传递给Javascript变量(并转义换行符)

我需要创建一个条形图来获取数据库中的数据.我为此下载了Highcharts.但是我无法在JavaScript中调用php变量.任何想法怎么做？

以及使用动态值创建图表的任何其他方式.

提前致谢.

<script>
$(function () {
    var chart;
    $(document).ready(function() {
        chart = new Highcharts.Chart({
            chart: {
                renderTo: 'container',
                type: 'column'
            },
            title: {
                text: 'Monthly Average Rainfall'
            },

您可以在脚本中使用PHP变量.请参阅下面的示例,将您的Php数组作为字符串.然后将其传递给系列数据.

   <?php

        $values= array('49.9', '71.5', '106.4', '129.2', '144.0', '176.0', '135.6', '148.5', 216.4, '194.1', '95.6', '54.4');
        $rainValues = implode(",", $values);
    ?>

然后,您可以在脚本中访问该字符串.

 series: [{
            name: 'Tokyo',
            data: [<?php echo $rainValues ?>]

        },
