【中文标题】MySQL到谷歌图表PHP【英文标题】：MySQL to google charts PHP 【发布时间】：2013-10-14 12:03:08 【问题描述】： <?php
$con=mysql_connect("xxxx.xxxx.xxxx.xx","Myuser","Mypass") or die("Failed to connect with database!!!!");
mysql_select_db("data", $con);
$sth = mysql_query("SELECT * FROM data");
$data = array (
'cols' => array(
array('id' => 'date', 'label' => 'Date ', 'type' => 'datetime'),
array('id' => 'temp1', 'label' => 'Temp 1', 'type' => 'number'),
array('id' => 'temp2', 'label' => 'Temp 2', 'type' => 'number')
),
'rows' => array()
);
while ($res = mysql_fetch_assoc($sth))
// array nesting is complex owing to to google charts api
array_push($data['rows'], array('c' => array(
array('v' => $res['date']),

<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", packages:["corechart"]);
google.setOnLoadCallback(drawChart);
function drawChart()
var bar_chart_data = new google.visualization.DataTable(<?php echo json_encode($data); ?>);
var options =
title: 'Weather data'
;
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(bar_chart_data, options);
</script>
</head>
<body>
<div id="chart_div" style="width: 900px; height: 500px;"></div>
</body>
</html>
我在完成此操作时遇到问题，echo count($bar_chart_rows_arr) AND echo count($task_submissions_arr) 显示出相应的良好结果（表中的行数）。图表框架正在显示，但没有表格/图表数据。有什么建议吗？

【问题讨论】：
$bar_chart_cols_arr 和 $bar_chart_rows_arr 的 JSON 输出是什么 - 它们是否与 Google Line Chart 的预期正确对应？ Google Line Chart Docs
你能发布 javascript 而不是神秘的 PHP 数组吗？
我们需要查看 json 编码数组的内容是什么，但我怀疑您的问题是您直接从数据库中输出日期而没有将它们转换为适当的格式。
更新了，temp1 & temp2 是 mysql 表中的 FLOAT，日期是时间戳。如果有任何遗漏，我会附上更多信息？
查看您的行的 json 输出 - 全部为“空”，因此为什么没有绘制图表。删除$task_submissions_arr[][] = $res;中多余的[]。
【参考方案1】：
根据您最初发布的代码 - 更改
$task_submissions_arr[][] = $res;
到
$task_submissions_arr[] = $res;
【讨论】：
请阅读 cmets，这个答案已经被提出，它不是解决方案。 你会注意到我是“根据你最初发布的代码”写的——即this code。无论如何，@asgallant 的答案也很有效。【参考方案2】：您的 PHP 代码为 Google Visualization API 生成格式不正确的 JSON。试试这个：
<?php
$con=mysql_connect("xxxx.xxxx.xxxx.xx","Myuser","Mypass") or die("Failed to connect with database!!!!");
mysql_select_db("data", $con);
$sth = mysql_query("SELECT * FROM data");
$data = array (
'cols' => array(
array('id' => 'date', 'label' => 'Date ', 'type' => 'datetime'),
array('id' => 'temp1', 'label' => 'Temp 1', 'type' => 'number'),
array('id' => 'temp2', 'label' => 'Temp 2', 'type' => 'number')
),
'rows' => array()
);
while ($res = mysql_fetch_assoc($sth))
// array nesting is complex owing to to google charts api
array_push($data['rows'], array('c' => array(
array('v' => $res['date']),
array('v' => $res['temp1']),
array('v' => $res['temp2'])
)));
?>
然后在你的javascript中：
var bar_chart_data = new google.visualization.DataTable(<?php echo json_encode($data); ?>);
【讨论】：
Okei，用你的代码更新了文本^，现在连图表框都没有显示，我做错了什么？ 你能更新输出的 HTML 以便我看看可能是什么原因吗？ 可能是这一行：'cols' ==> array( - ==> 应该是 =>
我注意到我遗漏的另一件事：var bar_chart_data = new google.visualization.DataTable(<?php echo json_encode($data); ?>); 行中的 echo。如果 PHP 代码正确，这将阻止图表接收任何数据。如果这不能解决问题，您将需要对 PHP 进行一些调试以找出它在哪里引发错误（您的服务器日志可能包含一些提示，但众所周知，PHP 在引发远触发的模糊错误方面很糟糕来自代码中实际问题的站点）。【参考方案3】：
感谢您在设计中的所有帮助，我有几个错误，但关键错误是我使用 MySQL 数据库中的 date, datetime 格式错误，当我从 date / datetime 更改它时到 string 代码就完成了！
$table['cols']=array(
array('label' => 'Date', type=>'string'),
array('label' => 'Temp 1', type=>'number'),
array('label' =>'Temp 2', type=>'number'),
);
杰森结果：
new google.visualization.DataTable("cols":["label":"Date","type":"string","label":"Temp 1","type":"number","label":"Temp 2","type":"number"],"rows":["c":["v":"2013-10-05 20:41:00","v":10.75,"v":4]
