将PHP数组转换为HTML面包屑

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.

Somthing like that?:

<ul>
<?php
foreach($crumb as $name=>$href){
   echo "<a href=/'$href'>$name</a>"; 
}

?>

<ul>
<li><a href="/">Home</a></li>
<?php
$path = '/';
foreach($crumbs as $name => $href) {
    echo '<li><a href="'.$path.$href.'/"></li>';
    $path .= $name.'/';
}
?>
</ul>

you can use this

<?php
function ConvertPHPArrayToBreadcrumb($arr) {
    //convert the php array to html breadcrumb as required in 
    //http://stackoverflow.com/questions/8464019/convert-php-array-to-html-breadcrumbs
    $crmbs = '<ul> <li><a href="/">Home</a></li>';
    foreach ($arr as $key => $val) {
        $crmbs .= '<li><a href="' . $val . '/">' . $key . '</a></li>';
    }
    $crmbs .= "</ul>";
    return $crmbs;
}


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

//call the convert function
$html_crumbs = ConvertPHPArrayToBreadcrumb($crumbs);

//echo the reuls
echo($html_crumbs);
?>

function showcrumbs($crumbs) {
    echo '<ul><li><a href="/">Home</a></li>';
    $path='/';
        foreach($crumbs as $name=>$href){
            echo '<li><a href="'.$path.$href.'">'.$name.'</a></li>'; 
            $path = $path.$href.'/';
        }
    echo '</ul>';
}

Usage:

<?php
function showcrumbs($crumbs) {
    echo '<ul><li><a href="/">Home</a></li>';
    $path='/';
        foreach($crumbs as $name=>$href){
            echo '<li><a href="'.$path.$href.'">'.$name.'</a></li>'; 
            $path = $path.$href.'/';
        }
    echo '</ul>';
}
$crumbs = array(
'Financial Accounting'  => 'financial',
'Ratio Analysis'        => 'ratios',
'Current Ratio'         => 'current-ratio'
);
showcrumbs($crumbs);
?>
