Blank page caused by Undefined index

[kporter.porter]

I upgraded my php from 4.4.7 to 5.2.4 and now the entire website doesn't work.  So I am trying to learn PHP and go through the site one error at a time.  If you have a idea why the upgrade caused the site to fail that would be great.

 

But in the meantime this is the problem i am stuck on.

 

I get this error now when transferring to a page

 

Notice - PHP Notice: Undefined index: REMOTE_ADDR in c:location\Session.php on line 45.

 

That line has the following code.

 

$GLOBALS["$SessionName"]=md5 (microtime() . $GLOBALS[REMOTE_ADDR"]);

 

Like I said this code worked before the upgrade.  Any idea what I can do to fix this problem?

 

Thanks in advance.

The element of the GLOBALS array is missing a quotation mark.

[marcus]

$GLOBALS["$SessionName"] = md5(microtime(). $GLOBALS["REMOTE_ADDR"]);

[kporter.porter]

Sorry that was a typing error when posting.  It has both quotes in the actual code.  I am rdping to the server so I didn't cut and paste.

 

Thanks.
