If last var is blank, no query_string is produced. This is running on a dell server with apache web server on linux

This will produce 
$_GET['var1'] = nothing! 
$_GET['var2'] = nothing! 
$_GET['var3'] = nothing! 

This will produce 
$_GET['var1'] = a 
$_GET['var2'] = b 
$_GET['var3'] = c 

This is really annoying since it has worked on 2 other servers that I have used. am I missing something? I've done some research and found that globals is ON, but with $_GET it doesn't matter if it's ON. 

What am I missing here? 

Also, there is no way I can POST these vars. I have certain pages with text links that I cannot process with a POST.

Here is a live test link to help you visualize the problem 
go to:

Reproduce code:
print "var1 = ".$_GET['var1']."<br>";
print "var2 = ".$_GET['var2']."<br>";
print "var3 = ".$_GET['var3']."<br>";
<META name="description" content="">
<META name="keywords" content="">
<META name="generator" content="CuteHTML">
<BODY BGCOLOR="#FFFFFF" TEXT="#000000" LINK="#0000FF" VLINK="#800080">
This screen is to test in inadequecies of php on<br><br>

<a href="testget.php?var1=a&var2=b&var3=c">link1 (good)</a>&nbsp;var1=a var2=b var3=c<br>
<a href="testget.php?var1=a&var2=b&var3=">link2</a>&nbsp;var1=a var2=b var3=<br>
<a href="testget.php?var1=&var2=b&var3=c">link3</a>&nbsp;var1= var2=b var3=c<br><br>

If you know how to fix this please let me know! go to <a href="" target="_blank"></a>


Expected result:
link 1: var1=a var2=b var3=c
link 2: var1=a var2=b var3=
link 3: var1= var2=b var3=c

Actual result:
link 1: var1=a var2=b var3=c
link 2: var1= var2= var3=
link 3: var1= var2=b var3=c

Link 3 is used to verify that if the last var has data the query string sends these three variables.
