Question

我正在尝试将MySQL数据库中的数据整齐地组织到表中。我几乎在那里，但是在使用while循环时遇到了一些麻烦。

发布我的简单代码：

<link type="text/css" rel="stylesheet" href="style.css"/>

<?PHP 
$connect = mysql_connect("localhost","root","");

mysql_select_db("users");
$query = mysql_query("SELECT * FROM users");
    WHILE($rows = mysql_fetch_array($query)):

        $username = $rows['username'];
        $password = $rows['password'];
        $email = $rows['email'];

    echo "
    <table>
    <thead>
    <th>Username</th>
    <th>Password</th>
    <th>Email Adress</th>
    </thead>
    <tr>
    <td>$username</td>
    <td>$password</td>
    <td>$email</td>
    ";
    endwhile;
?>

这给了我类似的输出：

Username    Password    Email Adress

test           123  test@test.no

Username    Password    Email Adress

testies 123 testies@test.no

Username    Password    Email Adress

tested  12345   tested@test.no

这里显而易见的问题是我的标题打印在while循环中，因此我为每个条目都获得了新的标题。这看起来真的很愚蠢，我宁愿让标题只显示一次。关于如何做到这一点的任何想法？

我试图在while循环之前用标题启动表，但后来<td> s不会与标题宽度对应，因为程序不会将它们识别为同一个表，因此不会需要匹配。

使用此

<link type="text/css" rel="stylesheet" href="style.css"/>

<?PHP 
$connect = mysql_connect("localhost","root","");

mysql_select_db("users"); ?>
<table>
    <thead>
    <th>Username</th>
    <th>Password</th>
    <th>Email Adress</th>
    </thead><?php 

$query = mysql_query("SELECT * FROM users");
    WHILE($rows = mysql_fetch_array($query)) { ?>                    
    <tr>
    <td><?php echo $rows['username']; ?></td>
    <td><?php echo $rows['password']; ?></td>
    <td><?php echo $rows['email']; ?></td>
    </tr>
<?php } ?>    
?>

按如下方式更改您的代码。

<?PHP 
$connect = mysql_connect("localhost","root","");

mysql_select_db("users");
$query = mysql_query("SELECT * FROM users");
  echo "
    <table>
    <thead>
    <th>Username</th>
    <th>Password</th>
    <th>Email Adress</th>
    </thead>";
WHILE($rows = mysql_fetch_array($query)):
        $username = $rows['username'];
        $password = $rows['password'];
        $email = $rows['email'];


echo"<tr>
    <td>$username</td>
    <td>$password</td>
    <td>$email</td>
    ";
    endwhile;
?>

Answer 3

在循环之前打印标题。

<table>
<thead>
<tr>
<th>Username</th>
<th>Password</th>
<th>Email Adress</th>
</tr>
</thead>
<?php 
$connect = mysql_connect("localhost","root","");

mysql_select_db("users");
$query = mysql_query("SELECT * FROM users");
    WHILE($rows = mysql_fetch_array($query)):

        $username = $rows['username'];
        $password = $rows['password'];
        $email = $rows['email'];

        echo "
        <tr>
        <td>$username</td>
        <td>$password</td>
        <td>$email</td>
        </tr>
        ";
    endwhile;
?>
</table>

Answer 4

试试这个：

<link type="text/css" rel="stylesheet" href="style.css"/>

<?php 
$connect = mysql_connect("localhost","root","");
mysql_select_db("users");
$query = mysql_query("SELECT * FROM users");
?>
    <table>
    <thead>
    <th>Username</th>
    <th>Password</th>
    <th>Email Adress</th>
    </thead>";
<?php
WHILE($rows = mysql_fetch_array($query)):

    $username = $rows['username'];
    $password = $rows['password'];
    $email = $rows['email'];
echo "<tr>
<td>$username</td>
<td>$password</td>
<td>$email</td>
";
endwhile;
?>
