Question

我想将表格排序到正确的部分。我有一个用户数据库，他们都有分配给每个用户的等级。在每个部分中都应该有一个表格，显示该等级中的所有用户。例如：

管理器

ID | rank    | username | email          | password
---------------------------------------------------
70 | Manager | MyUser   | email@mail.com | pswrd
---------------------------------------------------
70 | Manager | MyUser   | email@mail.com | pswrd

管理

ID | rank    | username | email           | password
---------------------------------------------------
9  | Admin   | userName | email@email.com | pswrd22

我想使用while循环来制作它。到目前为止我所拥有的：

<html>
<head>
</head>
<?php

    $tUsers_Select = "SELECT * FROM users LEFT JOIN ranks ON ranks.rankName = users.rank";
    $tRanks_Select = "SELECT * FROM ranks";

    $tUsers_Select_Query = mysqli_query($dbConnect, $tUsers_Select);
    $tRanks_Select_Query = mysqli_query($dbConnect, $tRanks_Select);

?>

<body>

    <?php

    while ($users_item = mysqli_fetch_array($tUsers_Select_Query, MYSQL_ASSOC)) {
        $ID = $users_item['ID'];
        $rank = $users_item['rank'];
        $username = $users_item['username'];
        $email = $users_item['email'];
        $password = $users_item['password'];
    }

    while ($ranks_item = mysqli_fetch_array($tRanks_Select_Query, MYSQL_ASSOC)) {
        $rankName = $ranks_item['rankName'];
        $value = $ranks_item['value'];

        echo '<h2>'.$rankName.'</h2>';
    }


    ?>



    <table border="1">
        <tr>
            <td>ID</td>
            <td>rank</td>
            <td>username</td>
            <td>email</td>
            <td>password</td>
        </tr>
        <tr>
            <td></td>
            <td></td>
            <td></td>
            <td></td>
            <td></td>
        </tr>
    </table>


</body>

准备好的陈述会更好。但是你走了

<?php


$tRanks_Select = "SELECT `rankName` FROM `ranks`";
$tRanks_Select_Query = mysqli_query($dbConnect, $tRanks_Select);

while ($ranks_item = mysqli_fetch_array($tRanks_Select_Query, MYSQL_ASSOC)) {
    $rankName = $ranks_item['rankName'];

    echo '<h2>'. $rankName .'</h2>';


    while ($users_item = mysqli_fetch_array($tUsers_Select_Query, MYSQL_ASSOC)) {

        $tUsers_Select = "SELECT `ID`, `rank`, `username`, `email`, `password` FROM `users` WHERE `rank` = '{$rankName}'";
        $tUsers_Select_Query = mysqli_query($dbConnect, $tUsers_Select);

        $ID       = $users_item['ID'];
        $rank     = $users_item['rank'];
        $username = $users_item['username'];
        $email    = $users_item['email'];
        $password = $users_item['password'];

        echo <<<EOD
            <table border="1">
                <tr>
                    <td>ID</td>
                    <td>rank</td>
                    <td>username</td>
                    <td>email</td>
                    <td>password</td>
                </tr>
                <tr>
                    <td>$ID</td>
                    <td>$rank</td>
                    <td>$username</td>
                    <td>$email</td>
                    <td>$password</td>
                </tr>
            </table>
        EOD;
    }
}

?>
