Don't use trim to strip the trailing / off of relative URLs!
<?php
trim($url, "/");
?>
It will also strip the / from the beginning of the URL. Instead, use this function:
<?php
function trimrelativeurl($url) {
$urlarry = explode($url);
foreach ($urlarry as $key => $val) {
if ($val == "/") $lastslash = $key;
}
if ($lastslash+1 == strlen($url))
$url = substr($url, 0, strlen($url)-1);
return $url;
}
?>
