Question

嗨我是新手到php并试图探索！我有一个问题，我的变量插入我的代码。继承我的变量

 $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';");

这就是我试图说出来的地方：

$(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',

这里确切地说是把我的变量放在哪里。无法弄清楚这一点。

    data: [$jul,$aug]

    }]
});
});

Answer 1

$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'];

您需要从我在解决方案中提供的每个对象中检索count的值

Answer 2

正如@aman所说，你需要执行查询。

您可以将您的结果分组到一个查询中，而不是多次调用Db

SELECT MonthCreated, count(id) AS result 
FROM tbl_users 
WHERE YearCreated = '2016'
GROUP BY MonthCreated

结果应该是：

[
    'June' => 11
    'July' => 34
    'August' => 56
];

如果您想通过两种方式设置这些数据：

1）如果你打印resposne js只是粘贴数据内联@ chris85说：

data: [<?php echo $jul, $aug ?>]

但这是一个丑陋的解决方案，只有在你学习的时候才允许。

2）加载默认的js（图表我猜）并通过Ajax调用数据。然后在PHP中您将返回Json编码数据。示例线程here

请使用像ADODB这样的专用库来防止ie。 SQL注入。它将更加可信，因为您将了解更多信息。

请不要在列名中使用camelCase。
