将PHP数组转换为HTML面包屑

Question

I want to convert the following php array:

$crumbs = array(
'Financial Accounting'  => 'financial',
'Ratio Analysis'        => 'ratios',
'Current Ratio'         => 'current-ratio'
);

to html breadcrumb as shown below:

<ul>
  <li><a href="/">Home</a></li>
  <li><a href="/financial/">Financial Accounting</a></li>
  <li><a href="/financial/ratios/">Ratios Analysis</a></li>
  <li><a href="/financial/ratios/current-ratio">Current Ratio</a></li>
</ul>

Anyone please show me how to do it in php. Thanks !!

UPDATE: Thanks for your help. Following is what worked for me:

<?php
$dotname = basename($_SERVER['PHP_SELF']);
$crumbs = array(
'Financial Accounting'  => 'financial',
'Ratio Analysis'        => 'ratios',
'Current Ratio'         => 'current-ratio'
);
echo("<ul>
<li><a href=\"/\">Home</a>&nbsp;&nbsp;&gt;</li>
");
foreach ($crumbs as $atext => $aloc) {
    if ($dotname != 'index.php' && $aloc == end($crumbs)) {
        $url .= '/'.$aloc;
        echo("<li><a href=\"$url\">$atext</a></li>
");
    } else {
        $url .= '/'.$aloc;
        echo("<li><a href=\"$url/\">$atext</a>&nbsp;&nbsp;&gt;</li>
");
    }
}
echo('</ul>');
?>

I'd go with a foreach and a variable to remember the path. I'll whip up an example in a few seconds.
