用PHP代码在HTML表中排序

Question

我在PHP中创建了一个简单的html表。 这是我的代码：图表->

    <div id="wrapper">
        <div class="chart">
            <h2>No. of Files Uploaded to Knowledge Base</h2>
            <table id="data-table" border="1" cellpadding="10"     cellspacing="0">


            <tr>
                    <td>Users</td>
                    <td>Project Files</td>
                    <td>Process Files</td>
                    <td>System Files</td>
                    <td>Total</td>
            </tr>   

                        <?php

                        $di = new RecursiveDirectoryIterator('upload/project/');
                        foreach (new RecursiveIteratorIterator($di) as $filename => $file) {

                        $pos = 15;
                        $file = substr("$filename", +$pos); 

                        $lenght = strlen($file);
                        $pos = strpos($file, "/");
                        $file = substr("$file",0,$pos);
                        if($file1 != '.DS_Store'){

                            $serverfiles = mysql_query("SELECT uploader FROM Project WHERE location = '$file'");

                            while($row = mysql_fetch_array($serverfiles)) {

                        }




                        $di = new RecursiveDirectoryIterator('upload/process/');
                        foreach (new RecursiveIteratorIterator($di) as $filename => $file) {

                        $pos = 15;
                        $file = substr("$filename", +$pos);

用户是从数据库表中填充的。 通过读取和计数目录中的文件数量来填充文件图形。 我希望能够按总数自动对表格进行排序，因此总数最高的用户将排在首位，依此类推。因此它看起来类似于联赛表格。

我不知道该怎么做。 有人可以指导我正确的方向吗？

Answer 1

为什么不也将其保存到数据库中？

SELECT uploader FROM Project WHERE location = '$file' ORDER BY field

否则，我将使用mysql_fetch_array所有用户的数据库查询放入一个数组中，遍历他们并计数文件，然后将此值存储到数组中。

然后对数组排序 （例如“ 按值（2）对多维数组排序 ”），然后再次对其进行迭代以输出。

Answer 2

无需内联回显所有内容，而是将所有数据存储在数组中，然后可以使用usort（）对数组进行排序。 然后只需遍历数组以回显值。

$table_rows = array(); //add this
$counter = 0; //add this
while($Load = mysql_fetch_array($uploader)){
    //...more code here but not going to put everything
    $counter++;
    $table_rows[$counter] = array();
    $table_rows[$counter]['username'] = $value;
    $table_rows[$counter]['project'] = $cnt;
    //...more code here but not going to put everything
}

function cmp_rows($a,$b) {
    if ($a['total'] == $b['total']) {
        return 0;
    }
    return ($a['total'] > $b['total']) ? -1 : 1;
}

usort($table_rows,'cmp_rows');

foreach($table_rows as $row) {
    echo "<tr>";
    echo "<td>{$row['username']}</td>";
    //...more code here but not going to put everything
}

方法1

根据您的要求，最好的方法是从数据库中获取排序结果，如下所示。

SELECT * FROM table_name WHERE ORDER BY field_name desc

方法2

您可以使用类似于array_multisort PHP函数对结果集进行排序。 阅读以下链接以获取示例。 几个链接如下所示。 谷歌获取更多链接。
