Multiple items in an array?? How??

Hi,
I have two items. They are
$cid = ea49678ab30e96367c238b1bc330996a;
$seo_username = str_replace(" ", "-", $user['username']);

I want to create another array that creates an md5 of these two. For example,
$md5idkey = $seo_username ; $cid;

How can i make it.

 

$md5idkey = md5($seo_username.$cid);

 

This doesnt work as the "." is also counted in the MD5. It must not be counted.

 

lol no it is not. The . concatenates the two strings before it gets hashed
example

$word1 = 'Jay';
$word2 = 'Gilford';
echo md5($word1.$word2);
echo '<br />';
echo md5('JayGilford');

PHP:

Both output the same value

344bd980647a7d117250fda88980e8d7
344bd980647a7d117250fda88980e8d7

Code (markup):

 

The . connects the two paremeters/values.
