一些PHP新手可能不知道如何结合PHP+MYSQL动态数据生成图表,我们这里以highcharts为例,教大家如何生成图表统计代码.
下面直接看代码:
<?php require_once 'config.php'; require_once 'functions.php'; /** * 作者:老季 * 网址:https://jiloc.com/42558.html */ ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>爬虫索引统计_<?php echo TITLE;?></title> <script type="text/javascript" src="http://cdn.hcharts.cn/jquery/jquery-1.8.3.min.js"></script> <script type="text/javascript" src="http://cdn.hcharts.cn/highcharts/highcharts.js"></script> <style> .jads{ text-align: center;} .jads table { margin: 0 auto; width: 600px; border:solid #e5e5e5; border-width: 1px 0px 0px 1px;} .jads table td{border:solid #e5e5e5; border-width: 0px 1px 1px 0px;} </style> </head> <body> <div class="jads"> <div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div> <p>本页面仅作展示使用,请定时或手动运行<a href="<?php%20echo%20DOMAIN_PATH;?>script.php">script.php</a>页面进行统计更新</p> <p><a href="<?php%20echo%20DOMAIN_PATH;?>">返回首页</a></p> <table> <tr> <td>日期</td> <td>索引</td> </tr> <?php $sql = "SELECT * FROM `analytics` ORDER BY a_time asc LIMIT 30"; $result = $pdo->prepare($sql); $result->execute(); $aAray = $result->fetchAll(); $rNums = count($aAray); $aDate = array(); $aRows = ''; $aAll = 0; for ($i=0;$i<$rNums;$i++){ $aDate[] = $aAray[$i]['a_time']; $aRows .= $aAray[$i]['rows'].','; $aAll += $aAray[$i]['rows']; ?> <tr> <td><a href="<?php%20echo%20DOMAIN_PATH;?>script.php?date=<?php echo $aAray[$i]['a_time']?>"><?php echo $aAray[$i]['a_time']?></a></td> <td><?php echo number_format($aAray[$i]['rows']);?></td> </tr> <?php } ?> <tr> <td></td> <td>共计:<?php echo number_format($aAll);?></td> </tr> </table> </div> </body> <script type="text/javascript"> $(function () { $('#container').highcharts({ title: { text: '<?php echo TITLE;?>', x: -20 //center }, credits: { enabled: false //去掉highcharts网站url }, xAxis: {categories: <?php echo json_encode($aDate);?> }, yAxis: { title: { text: '' }, plotLines: [{ value: 0, width: 1, color: '#808080' }] }, tooltip: { valueSuffix: '' }, legend: { layout: 'vertical', align: 'right', verticalAlign: 'middle', borderWidth: 0 }, series: [{ name: '<?php echo TITLE;?> 爬虫', data: [<?php echo rtrim($aRows,',');?>] }] }); }); </script> <?php echo STATISTICS;?> </html>
需要注意的地方已用红字标注,
categories :json_encode(数字),外面没有方括号。
data : 直接拼接承字符串接口。
