Test php script.

[root@alpha root]# cat /var/www/html/test.php 
<?php
reset($_GET);
var_dump($_GET);
?>

Test URLS.

1 - http://localhost/test.php?a=1&b=2&c
2 - http://localhost/test.php?a=1&b=2&c=
3 - http://localhost/test.php?c&b=2&a=1
4 - http://localhost/test.php?c=&b=2&a=1

Results.

1 array(2) { ["a"]=> string(1) "1" ["b"]=> string(1) "2" }
2 array(3) { ["a"]=> string(1) "1" ["b"]=> string(1) "2" ["c"]=> string(0) "" } 
3 array(2) { ["c"]=> string(0) "" ["b"]=> string(1) "2" }
4 array(3) { ["c"]=> string(0) "" ["b"]=> string(1) "2" ["a"]=> string(1) "1" }

Variable count seems to be calculated by the number of ='s (Note how a=1 drops off the argument list when the first param has no '=' associated with it.)

?a is legal html
however as far as I can tell all forms must pass in ?a= to make a valid variable

I'm unsure what to class this as (bug or feature)

It was reported to Red Hat as https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=72752

Commets?
