需要帮助我的PHP代码在breadcrumb上获取错误的目录

Question

my php breadcrumb code is below and the problem is, this is my directory

http://domain.com/folder

using the code below i get directory like this

Home » » Folder instead of Home » Folder

i don't know what is wrong in the code

<?php
    $file = basename($_SERVER["PHP_SELF"]);

    $filename = (count(explode('.', $file)) === 1 ? $file : implode('.', array_slice(explode('.', $file), 0, (count(explode('.', $file))-1))));

    $Pages = array(
        $filename => 'Folder'
    );

    $path = $_SERVER["PHP_SELF"];
    $parts = explode('/',$path);
    if (count($parts) < 2)
    {
    echo("home");
    }
    else
    {
    echo ("<a href=\"http://domain.com\">Home</a> &raquo; ");
    for ($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> &raquo; ");
            }
        else
            {
            $str = $parts[$i];
            $pos = strrpos($str,".");
            $parts[$i] = substr($str, 0, $pos);
            echo str_replace('-', ' ', $Pages[$parts[$i]]);
            };
        };
    };  
?>

Here's my second code

<?php
    $file = basename("/".$_SERVER["PHP_SELF"]);

    $filename = (count(explode('.', $file)) === 1 ? $file : implode('.', array_slice(explode('.', $file), 0, (count(explode('.', $file))-1))));
    $Pages = array(
        'folder' => 'Folder',
        $filename => 'Folder'
    );

    $path = "/".$_SERVER["PHP_SELF"];
    $parts = explode('/',$path);
    if (count($parts) < 2)
    {
    echo("home");
    }
    else
    {
    echo ("<a href=\"http://domain.com\">Home</a>  ");
    $cnt = count($parts);
    for ($i = 2; $i < $cnt; $i++)
        {
        if (!strstr($parts[$i],"."))
            {
            echo("&raquo; <a href=\"");
            for ($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]]);
            };
        };
    };  
?>

Start the for loop which uses $i as index with initial value 2 instead of 1.

<?php
    $file = basename("/".$_SERVER["PHP_SELF"]);

    $filename = (count(explode('.', $file)) === 1 ? $file : implode('.', array_slice(explode('.', $file), 0, (count(explode('.', $file))-1))));
    $Pages = array(
        $filename => 'Folder'
    );

    $path = "/".$_SERVER["PHP_SELF"];
    $parts = explode('/',$path);
    if (count($parts) < 2)
    {
    echo("home");
    }
    else
    {
    echo ("<a href=\"http://domain.com\">Home</a>  ");
    $cnt = count($parts);
    for ($i = 1; $i < $cnt; $i++)
        {
        if (!strstr($parts[$i],"."))
            {
            echo("&raquo; <a href=\"");
            for ($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]]);
            };
        };
    };  
?>
