Try something like this:
$subPath = '';
$path = explode('/', $_SERVER['REQUEST_URI']);
array_shift($path);
foreach ($path as $segment) {
$subPath.= $segment.'/';
echo "$segment / ";
}
You may need to tweak it a bit, but that's the basic idea.
[EDIT]
Or maybe something like this:
$Pages = [
'/clothes' => 'Clothes',
'/clothes/something.php' => 'Something'
];
$subPath = '';
$BreadCrumbs = [];
$path = explode('/', $_SERVER['REQUEST_URI']);
array_shift($path);
foreach ($path as $segment) {
$subPath.= '/'.$segment;
$BreadCrumbs[] = "$Pages[$subPath]";
}
echo implode(' > ', $BreadCrumbs);
If your version of PHP is before 5.4.0, then you'll need a different syntax for the arrays:
$Pages = array(
'/clothes' => 'Clothes',
'/clothes/something.php' => 'Something'
);
$BreadCrumbs = array();
[EDIT]
OK, one last go:
<?php
$Pages = array(
'clothes' => 'Clothes',
'something' => 'Something'
);
$path = $_SERVER["PHP_SELF"];
$parts = explode('/',$path);
if (count($parts) < 2)
{
echo("home");
}
else
{
echo ("Home » ");
for ($i = 1; $i < count($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> » ");
}
else
{
$str = $parts[$i];
$pos = strrpos($str,".");
$parts[$i] = substr($str, 0, $pos);
echo str_replace('-', ' ', $Pages[$parts[$i]]);
};
};
};
?>
