问题描述
我正在尝试将 PHP 数组变量转换为 JavaScript 变量.
I am trying to get a PHP array variable into a JavaScript variable.

function drawChart(row,day,week,month,date)
{
// Some code...
}
</script>
</head>

switch($au[$counter]->id)
{
case pageID.'/insights/page_active_users/day':
$day[] = $au[$counter]->value;
break;
case pageID.'/insights/page_active_users/week':
$week[] = $au[$counter]->value;
break;
case pageID.'/insights/page_active_users/month':
$month[] = $au[$counter]->value;
break;
}
}
?>
<script>
drawChart(600/50, '<?php echo $day; ?>', '<?php echo $week; ?>', '<?php echo $month; ?>', '<?php echo createDatesArray(cal_days_in_month(CAL_GREGORIAN, date('m',strtotime('-1 day')), date('Y',strtotime('-1 day')))); ?>');
</script>
</body>

推荐答案
在下面的例子中你有一个 PHP 数组，然后首先通过一个 PHP 数组创建一个 JavaScript 数组:
In the following example you have an PHP array, then firstly create a JavaScript array by a PHP array:
<script type="javascript">
day = new Array(<?php echo implode(',', $day); ?>);
week = new Array(<?php echo implode(',',$week); ?>);
month = new Array(<?php echo implode(',',$month); ?>);
<!-- Then pass it to the JavaScript function: -->
drawChart(<?php echo count($day); ?>, day, week, month);
</script>
