Description:
------------
W3C spec indicates that valid separators for name value pairs are "&" and ";". 

http://www.w3.org/TR/REC-html40/appendix/notes.html#h-B.2.2

"We recommend that HTTP server implementors, and in particular, CGI implementors support the use of ";" in place of "&" to save authors the trouble of escaping "&" characters in this manner."

This becomes an issue when you are dealing with xml/xsl/xhtml, because you can no longer use:

http://host/script.php?var1=bob&var2=jim

instead, you have to use:

http://host/script.php?var1=bob&var2=jim

PHP should follow the W3C recommendation and support ";" as a delimiter for name/value pairs in URLs

Reproduce code:
---------------
<xmp>
<?php

print_r ($_GET);

?>
</xmp>

And then call this script with this query string:
?var1=bob;var2=jim

Expected result:
----------------
Array
(
    [var1] => bob
    [var2] => jim
)

Actual result:
--------------
Array
(
    [var1] => bob;var2=jim
)
