PHP会话销毁

如何在php中销毁会话

问题是，当用户单击注销按钮时，会话将结束，他将被重定向到index.php

Customer.php

<?php 

session_start(); 
#include("Connection.php");
if (isset($_POST['submit'])) { 
$name = $_POST['customerName']; 
$_SESSION['user'] = $name; 
} 
if (isset($_SESSION['user'])) { echo "Hello {$_SESSION['user']}, welcome back"; }
else{echo "walang tao";}

$sql="INSERT INTO ORDERS(Name) VALUES('$name')";
mysql_query($sql);

session_destroy();
?>
<button><a href="Customer.php"></a></button>

---

您还可以使用
unset（）
函数来释放会话环境

if (isset($_SESSION['user']))
{
  unset($_SESSION['user']);
  header('location:index.php');
}

将此文件包含在标题中，并在文件中设置所需的设置。
它应该很有效

<?php
    session_cache_expire(20);
    if (!isset($_SESSION)) {    
        session_start();
    }
    // set timeout period in seconds
    $inactive = 1200; // timeout for the session
    // check to see if $_SESSION['timeout'] is set
    if(isset($_SESSION['timeout']) ) {
        $session_life = time() - $_SESSION['timeout'];
        if($session_life > $inactive) {
            $_SESSION = array();
            if(isset($_COOKIE[session_name()])) {
                setcookie(session_name(), '', time()-42000, '/');
            } 
            session_destroy(); 
            header("Location: index.php"); // or whatever you prefer to do. 
        }
    }
    $_SESSION['timeout'] = time();
?>

如果您不使用auth组件，那么它非常简单

public function logout(){
    $this->Session->destroy();
    // no cake we really want you to delete it because you suck
    $this->Session->destroy();
}

会话_destroy（）

session_unset（）//函数释放当前注册的所有会话变量
 将index.php替换为Customer.php当您看到Bobby Tables时，请代我向他问好。您的Customer.php文件中已经有一个
session\u destroy
调用了吗？“注销按钮”链接到哪里？因为我希望用户重定向到index.php页面
<?php
    session_cache_expire(20);
    if (!isset($_SESSION)) {    
        session_start();
    }
    // set timeout period in seconds
    $inactive = 1200; // timeout for the session
    // check to see if $_SESSION['timeout'] is set
    if(isset($_SESSION['timeout']) ) {
        $session_life = time() - $_SESSION['timeout'];
        if($session_life > $inactive) {
            $_SESSION = array();
            if(isset($_COOKIE[session_name()])) {
                setcookie(session_name(), '', time()-42000, '/');
            } 
            session_destroy(); 
            header("Location: index.php"); // or whatever you prefer to do. 
        }
    }
    $_SESSION['timeout'] = time();
?>

public function logout(){
    $this->Session->destroy();
    // no cake we really want you to delete it because you suck
    $this->Session->destroy();
}

//If you want complete destroy session then you can write.
