You can use PHP variables inside scripts. See an example below, make your Php array as a string. Then pass it to series data.
您可以在脚本中使用 PHP 变量。请参见下面的示例，将您的 PHP 数组设为字符串。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);
?>
Then, you can access the string in script.
然后，您可以访问脚本中的字符串。
series: [{
name: 'Tokyo',
data: [<?php echo $rainValues ?>]
},

For using any PHP variable in JavaScript you need to echo the PHP value and initialize it to JavaScript variable.
要在 JavaScript 中使用任何 PHP 变量，您需要回显 PHP 值并将其初始化为 JavaScript 变量。
<script type="text/javascript">
var myjsvar= <?php echo $my_phpvar; ?>
</script>
