Following a catastrophe with my home hosted sites, i’ve moved back to remote hosting again.  I had a disk failure, should be fine as I have backups right?  Ah, yeh, i’d not gotten around to putting them onto removable media yet…&#82…

<?php echo $_GET['xD']; ?>

On some PHP installations you get warnings if the index ‘xD’ is not defined. I have created the following function to echo a querystring variable.

<?php

function egv($name,$default=”){
echo htmlentities((isset($_GET[$name])) ? $_GET[$name] : $default);
}

?>

and you would call it like so:

<?php egv(’xD’); ?>
