php html

如何在html中格式化php？,php,html,Php,Html,我有一个简单的test.php脚本： <?php $name = $_GET['name']; $response = "Hi, ".$name."! How are you?"; echo $response; ?> 正如您所看到的，有一个带有模板的html页面，并且只需要在一个位置（页面中间）进行响应。我不想重复整个html脚本如果我把php脚本放到html中，那么我的php脚本就会公开示例链接：www.domain.com/test.php？n

我有一个简单的

test.php

脚本：

<?php

    $name = $_GET['name'];
    $response = "Hi, ".$name."! How are you?";
    echo $response;

?>

正如您所看到的，有一个带有模板的html页面，并且只需要在一个位置（页面中间）进行响应。我不想重复整个html脚本

如果我把php脚本放到html中，那么我的php脚本就会公开

示例链接：

www.domain.com/test.php？name=John

用which.php保存此页面

   <html>
   <title>Your name</title>
   <body>
   <center>Welcome to the coolest page ever</center>
   <br>
   <?php if(isset($_GET['name'])) { $response = "Hi, ".$_GET['name']."! How are you?"; 
   echo $response;}
   ?>
   <br>
   <u>This is the footer</u>
   </body></html>


你的名字
欢迎来到有史以来最酷的页面




这是页脚

您可以将html放入php页面test.php中

下面是我如何在html内部使用echo来显示值的示例

首先，使用php连接到数据库并执行所需的任何查询

我还使用includes使处理每个页面的页眉/导航和页脚变得简单。不必在test.php页面中包含这些代码，您可以创建单独的页面并只包含它们。这样，如果你想编辑你的页眉或页脚，你可以在一个地方做，它将改变你的所有页面。正如您将在我的html中看到的，您可以将echo值放入html中，如so value=”

//php code begins here
<?php

include_once 'header.php';

$sql = "SELECT * FROM `person` WHERE person_id = " .$user_id." ";

$conn = mysqli_connect( $dbServername , $dbUsername , $dbPassword , $dbName );
$result = $conn->query($sql);

if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
    echo "user_id: " . $row["person_id"]. " - person_id: " . $row["person_first"]. " " . $row["person_last"]. "<br>";
    $person_id = $row["person_id"];
    $person_first = $row["person_first"];
}
} else {
echo $sql;
}
$conn->close();

?>

是否要在指定的html位置打印响应变量@ⵍⵢⴻⵙ 是的，基本上是这样。你可以使用Ajax。如果你想使用PHP，你可以使用“PHP就在这里”。你可能需要添加一个PHP处理程序，使PHP能够在.html文件上执行，并且该方法将根据你的服务器架构（Apache/Nginx/IIS）而有所不同。您也可以使用javascript或jQuery在运行时打印变量。如果我这样做，人们可以从view source或inspect Element中查看我的php代码php代码在前端从未显示。浏览器中将只显示回显文本。如果我这样做，人们可以从view source或inspect Element中查看我的php代码，所以您可以使用include来执行此操作。例如，页面顶部包含的my header.php代码在此页面源代码中不可见
<?php
include 'includes/dbh.php';

session_start();
if (!isset($_SESSION["u_id"]))
{
  header("location: login.php");

$user_id = $_SESSION['u_id'];

$sql = "SELECT * FROM users WHERE user_id='$user_id'";
