UBB.Developers Forums Community Development Programming PHP and Server-side Scripting String Query

Hi,

What does each . mean in this string?

$andids .= " <a href="{$config['phpurl']}/showprofile.php?Cat=$Cat&User=" . $Unums[$i] . "" target="_blank">" . $andusrn . "</a> ";

This works, yet....

$andids .= " " . $Unums[$i] . "( " . $andusrn . " )";

fails and crashes threads. Okay I realise I could probably reduce the length there, but all I have done is to remove the html code and add a ( and a ) around $andusrn

Clearly I am missing someting simple and obvious.
