对于下面的代码，我通过使用href方法从另一个页面按传递了4个参数。这样，在这段代码中，我使用GET方法接收所有这4个值，并在不同的值下回显它们。但是，当我想通过按标题返回到index.php时，它不会将我定向到该页面。即使它应该引导我的正确链接是index.php，也会将我引导到bookingdays.php / index.php。请帮助我，谢谢！
<?php
if($_GET != NULL){
$price = $_GET['price'];
$duration= $_GET['duration'];
$car = $_GET['car'];
$imgLink=$_GET['image'];
}
else{
header("location:index.php");
}
?>

答案 0 :(得分：0)
您可以尝试使用location:../index.php或location:/index.php。前者将您带到index.php的目录，后者将您带到顶层目录，然后index.php
