PHP会话不适用于IIS 7.5

Question

I have an IIS server with multiple virtual hosts running from the default site, these host all use PHP and create login sessions daily.

I recently added a new site (new domain) in IIS and the virtual directories I put in this site cant't create PHP sessions. I tried the following basic test which works in the default website.

session_start();
$_SESSION['test'] = 'my_test_value';
echo $_SESSION['test'];

So I load the page to store the session value then comment out the second line and load again and I get..

PHP Notice:  Undefined index: test 

Have I configured the site incorrectly or do I need to enable something in PHP, like I said the default site has not problems creating sessions, and this is the first time I have added a second site to IIS so I am a bit of a newbie.

Answer 1

I resolved this by installing an instance of PHP 5.6 and pointing the new site to the new instance of PHP and leaving the old site pointing to 5.3
