    $var = "<a href='JavaScript:newPopup(\"http://www.yourfantasyfootballreality.com/register.php\");' class='two'>Register</a> | <a href='JavaScript:newPopup(\"http://www.yourfantasyfootballreality.com/signin.php\");' class='two'>Sign In</a>";
} else {
    $var = "Hello, ".$_SESSION['color'] ."! | " . "<a href=\"http://www.yourfantasyfootballreality.com/index.php\" onclick=\"destroyphpsess()\" class='two'>Log Out</a>";
}
echo $var;

Now I need to define the javascript function. This is where I am having trouble. This is the basic outline I have so far...

function destroyphpsess()
{
<?php
session_destroy();
?>
}

如果有人可以帮助我使用该功能，我将不胜感激！谢谢.

If someone could help me with the function I would appreciate it! Thanks.

推荐答案

您的JavaScript运行在客户端，而您的PHP运行在服务器端.您不能以这种方式从JavaScript调用PHP函数.您有两种选择:

Your JavaScript runs client-side, and your PHP runs server-side. You can't call PHP functions from JavaScript this way. You have two options:

1. 对服务器端脚本进行AJAX调用，以清除会话数据(为确保一致性并正确清除服务器端的内容，建议这样做)
2. 使用JavaScript 清除PHPSESSID cookie(如果重新配置会话处理方式或URL参数处理会话，则无效)
