通过php构建搜索结果页面

我需要建立HTML页面来显示和组织我的结果。我应该把HTML放在哪里？我试过了，但还是出错了。它是否在php脚本中？在php脚本之后？之前困惑

<?php

if (isset($_POST['Submit'])) {
if (!empty($_POST['reg'])) {

    $record = $_POST['reg'];

    $query = mysql_query("SELECT * FROM reg_add WHERE reg='" . mysql_real_escape_string($record) . "'");
    $result = mysql_num_rows($query);

    if ($result != 0) {

        $row = mysql_fetch_array($query);

        $connect_date = $row['connect_date'];
        $reg = $row['reg'];
        $first_name = $row['first_name'];
        $last_name = $row['last_name'];
        $nickname = $row['nickname'];
        $gender = $row['gender'];
        $birthday = $row['birthday'];
        $home_state = $row['home_state'];
        $national = $row['national'];
        $location = $row['location'];


    } else {
        header("Location: search_error1.php");
        exit;
    }

} else {
    header("Location: search_error2.php");
    exit;
}
}
?>

PHP可嵌入HTML，因此您可以在PHP文件中编写HTML标记。您只需将所有php代码放入
：



PHP解释器只是忽略在PHP标记（
）之外写入的所有文本，并将其直接写入stdout

因此，对您来说，它将是这样的：

<?php

// ...

if ($result != 0) {
    while($row = mysql_fetch_array($query)) {
        $connect_date = $row['connect_date'];
        $reg = $row['reg'];
        $first_name = $row['first_name'];
        $last_name = $row['last_name'];
        $nickname = $row['nickname'];
        $gender = $row['gender'];
        $birthday = $row['birthday'];
        $home_state = $row['home_state'];
        $national = $row['national'];
        $location = $row['location'];
?>
  First name: <?php echo $first_name ?><br/>
  Last name: <?php echo $last_name ?><br/>
  ...
<?php
    }
}

// ...

?>

我尝试了它，但出现了错误
您尝试了什么，出现了什么错误？我尝试了您编写的内容，但我的错误页面在脚本中无法正常工作。以下内容似乎不起作用：}else{header（“Location:search_error1.php”）；exit；}else{header（“Location:search_error2.php”）；退出；同样，如果我输入了错误的号码或没有号码，则错误页面不工作。您所说的“错误页面不工作”是什么意思？没有重定向到search_error1.php或什么？
<?php

// ...

if ($result != 0) {
    while($row = mysql_fetch_array($query)) {
        $connect_date = $row['connect_date'];
        $reg = $row['reg'];
        $first_name = $row['first_name'];
        $last_name = $row['last_name'];
        $nickname = $row['nickname'];
        $gender = $row['gender'];
        $birthday = $row['birthday'];
        $home_state = $row['home_state'];
        $national = $row['national'];
        $location = $row['location'];
?>
  First name: <?php echo $first_name ?><br/>
  Last name: <?php echo $last_name ?><br/>
  ...
<?php
    }
}
