echo ("Home » ");
for ($i = 2; $i < count($parts); $i++) {
if (!strstr($parts[$i], ".")) {
echo("<a href=\"");
for ($j = 0; $j <= $i; $j++) {
echo $parts[$j] . "/";
};
echo("\">" . str_replace('-', ' ', $Pages[$parts[$i]]) . "</a> » ");

$str = $parts[$i];
$pos = strrpos($str, ".");
$parts[$i] = substr($str, 0, $pos);
echo str_replace('-', ' ', $Pages[$parts[$i]]);

This should do it:
// get this-shirt.php from the URL
$file = basename($_SERVER["PHP_SELF"]);
// pure magic
$filename = (count(explode('.', $file)) === 1 ? $file : implode('.', array_slice(explode('.', $file), 0, (count(explode('.', $file))-1))));
$Pages = array(
'clothes' => 'Clothes',
'shirt' => 'shirt',
$filename => 'This Shirt' // use $filename to declare the array's key
);
