嗨，我是php新手，正在尝试探索！在代码中插入变量时遇到问题。这是我的变量
$jun = mysql_query("SELECT count(*) from tbl_users where MonthCreated = 'June' and YearCreated = '2016';");
$jul = mysql_query("SELECT count(*) from tbl_users where MonthCreated = 'July' and YearCreated = '2016';");
$aug = mysql_query("SELECT count(*) from tbl_users where MonthCreated = 'August' and YearCreated = '2016';");
$sep = mysql_query("SELECT count(*) from tbl_users where MonthCreated = 'September' and YearCreated = '2016';");
$oct = mysql_query("SELECT count(*) from tbl_users where MonthCreated = 'October' and YearCreated = '2016';");
$nov = mysql_query("SELECT count(*) from tbl_users where MonthCreated = 'November' and YearCreated = '2016';");
$dec = mysql_query("SELECT count(*) from tbl_users where MonthCreated = 'December' and YearCreated = '2016';");
我想把它放在这里：
$(function () {
$('#container').highcharts({
title: {
text: 'Monthly Average Requests',
x: -20 //center
},
subtitle: {
text: 'Source: Barangay Harapin ang Bukas',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Volume'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '' //suffix *C
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [{
name: 'Complaints',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9,20]
}, {
name: 'Services',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}, {
name: 'Registered Constituents',
这正是我想放变量的地方。我想不通。
data: [$jul,$aug]
}]
});
});
$result = mysql_query("SELECT count(*) as count from tbl_users where MonthCreated = 'June' and YearCreated = '2016';");
$row = mysql_fetch_assoc($result);
$jun = $row['count'];
$result = mysql_query("SELECT count(*) as count from tbl_users where MonthCreated = 'July' and YearCreated = '2016';");
$row = mysql_fetch_assoc($result);
$jul = $row['count'];
$result = mysql_query("SELECT count(*) as count from tbl_users where MonthCreated = 'August' and YearCreated = '2016';");
$row = mysql_fetch_assoc($result);
$aug = $row['count'];
$result = mysql_query("SELECT count(*) as count from tbl_users where MonthCreated = 'September' and YearCreated = '2016';");
$row = mysql_fetch_assoc($result);
$sep = $row['count'];
$result = mysql_query("SELECT count(*) as count from tbl_users where MonthCreated = 'October' and YearCreated = '2016';");
$row = mysql_fetch_assoc($result);
$oct = $row['count'];
$result = mysql_query("SELECT count(*) as count from tbl_users where MonthCreated = 'November' and YearCreated = '2016';");
$row = mysql_fetch_assoc($result);
$nov = $row['count'];
$result = mysql_query("SELECT count(*) as count from tbl_users where MonthCreated = 'December' and YearCreated = '2016';");
$row = mysql_fetch_assoc($result);
$dec = $row['count'];
您需要从每个对象中检索count的值，就像我在解决方案中给出的那样
正如@aman所说，您需要执行查询。
您可以将您的结果分组在一个查询中，而不是多次调用Db
SELECT MonthCreated, count(id) AS result
FROM tbl_users
WHERE YearCreated = '2016'
GROUP BY MonthCreated
结果应该看起来像：
[
'June' => 11
'July' => 34
'August' => 56
];
如果你想设置这些数据有两种方式：
1） 如果你打印resposne js，只需像@chris85所说的那样内联粘贴数据：
data: [<?php echo $jul, $aug ?>]
但这是一个丑陋的解决方案，只有当你学会了才允许。
2） 加载默认的js（我想是图表）并通过Ajax调用数据。然后在PHP中，您将返回Json编码的数据。此处为示例线程
请使用像ADODB这样的专用库，以防止SQL注入。它会更舒适，因为你会学到更多。
请不要在列名中使用camelCase。
