我在div标记层中放置echos时遇到问题。。我尝试了很多次将div标记层放在里面，这样我就可以很容易地在页面上移动结果"name"，所以当它在浏览器上显示时，它可以是页面的左侧、右侧或中心。在此之前，我曾尝试在HTML中回显它，但没有成功。。下面是我的页面脚本--useracc-test.php
<?php
//useracc-test.php
session_start();
// require 'lib/password.php';
require 'connect-test.php';
$userName=$_POST['username'];
//$sql = "SELECT name, username FROM users WHERE username = '" . $_POST['username'] . "'";
//$result = $conn->query($sql);
$query = sprintf("select name, username, telno FROM users WHERE username='%s'", mysql_real_escape_string($userName));
$result = $conn->query($query); ?>
<?php while($row=$result->fetch_assoc()): ?>
<div id="satu"><?= $row['name'] ?></div>
<div id="dua"><?= $row['username'] ?></div>
<div id="tiga"><?= $row['telno'] ?></div>
<?php endwhile; ?>
<html>
<head>
<style type="text/css">
#apDiv2 {
position: absolute;
left: 51px;
top: 238px;
width: 237px;
height: 93px;
z-index: 1;
}
#apDiv1 {
position: absolute;
left: 50px;
top: 344px;
width: 234px;
height: 104px;
z-index: 2;
}
</style>
</head>
<body>
<div id="apDiv2"><span class="error"><?php echo $userName; ?></span></div>
<div id="apDiv1"><span class="error"><?php echo $row['telno'] ?></span></div>
</body>
</html>
如果希望结果显示在正文中，则需要在正文中回声/输出结果。只需将块复制到HTML正文中，如下所示：
<body>
<div id="apDiv2"><span class="error"><?php echo $userName; ?></span></div>
<div id="apDiv1"><span class="error"><?php echo $row['telno'] ?></span></div>
<?php while($row=$result->fetch_assoc()): ?>
<div id="satu"><?= $row['name'] ?></div>
<div id="dua"><?= $row['username'] ?></div>
<div id="tiga"><?= $row['telno'] ?></div>
<?php endwhile; ?>
</body>
</html>
