And odd bug happens if you're not extremely clean with your css declarations. If you
concatenate a value onto a session variable via $_SESSION['varname'] .=
"morestuff"; and you have this in your <body> style definiton:
background-image: url(); background-repeat: no-repeat;
the value you write to the session variable will be saved to the session variable TWICE. I.e.
<?php
session_start();
$_SESSION['varname'] .= "addon";
echo $_SESSION['varname'];
?>
with a body tag like this:
<body style="background-image: url(); background-repeat: no-repeat;">
will output:
"addon"
the first visit, and then
"addonaddonaddon"
on the subsequent hit, and add two "addon"'s every hit to the page.
