$ _SESSION在URL中没有文件名时不能正常工作？

Question

I'm currently working on a site where I'm trying to make use of the session variables.

I have a controller script (index.php) that begins with session_start(); and has two different HTML files included within if statements. Everything works all groovy when I go to /quote/index.php, the session variables that I've set are echoed on the page as expected, however if I remove 'index.php*' from the URL so it points to just /quote the page loads however none of the session variables show up.

I'm not using session_destroy anywhere in my scripts and the session variables aren't echoing '0' so I'm fairly sure they aren't being unset, it seems as though they are just ignored without the filename in the URL!

Any insight as to why this is occuring would be awesome, Thanks

/quote/index.php (with extraneous bits removed):

<?php
session_start();

if (isset($_GET['form']))
    {
include 'form.html.php';
exit();
    }
if (isset($_GET['fetchquote'])) 
    {
    $width = mysqli_real_escape_string($link, $_POST['width']);
    $height = mysqli_real_escape_string($link, $_POST['height']);
    $_SESSION['height'] = $height;
    $_SESSION['width'] = $width;
    }
include 'quote.html.php';
?>

The session variables are echoed in quote.html.php

what are the two file names? seems that one of the file that you are including is named index.html and resides in the mysite.com/quote/ itself. And if I am not wrong, if in a directory there are index.html and index.php then the index.html is loaded by default unless the file is explicitly specified in the url. So it seems in your case when you are not specifying the index.php explicitly,the index.html is being loaded.Of course this is the case only if there is an index.html there in the directory.
