PHP - Breadcrumb With Re-written Url

This script works fine except, the a href only displays baseurl/current_folder instead of baseurl/other_folder/other_folder/current_folder

I'm sure it's simple, but I can't figure it out.

Code: [Select]
function breadcrumbs($separator = '', $home = 'Home') {

    $path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));
    $base_url = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';
    $breadcrumbs = array("<p><a href=\"$base_url\">$home</a></p>");

    $last = end(array_keys($path));

    foreach ($path AS $x => $crumb) {
        $title = ucwords(str_replace(array('.php', '_'), Array('', ' '), $crumb));
        $title = ucwords(str_replace(array('.html', '_'), Array('', ' '), $crumb));
        if ($x != $last){
            $breadcrumbs[] = "<p><a href=\"$base_url$crumb\">$title</a></p>";
        }else{
            $breadcrumbs[] = "<p>$title</p>";
}
    }

    return implode($separator, $breadcrumbs);
}

echo breadcrumbs();

I have a breadcrumb scrpt that works well except I want it to be like the breadcrumb script here on phpfreaks.

I need to get parts of the url that the script gets to create the trail and query the database to replace those parts of the url.

Say i have a url like mydomain.com/forum/1/2,  where 1 is the board and 2 topic, how would i change the code so if the part[1] was forum it replaces parts 2 and 3 with what it's in the database?

Here is my breadcrumb script

function breadcrumb(
            $home = 'Home', // Name of root link
            $division = ' / ', // Divider between links
            $hidextra = true, // Toggle hide/show get data and fragment in text
            $index = false,  // Toggle show/hide link to directory if it does not contain a file
            $indexname = 'index.php' // The definition of the file the directory must contain
) {

$breadcrumb="";

    // Requested addons...
    $extension = '.php'; // Extension to cut off the end of the TEXT links
    $ifIndex = 'index.php'; // Filename of index/default/home files to not display
    // End requested addons

    $whole = $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

    $parts = explode('/', $whole);
    $parts[0] = 'http://'.$parts[0];

$array = array('-', '%20');

    $breadcrumb .=  "<a href=\"{$parts[0]}\">{$home}</a>{$division}";
    $k = 1;
    for ($i=1;$i < sizeof($parts);$i++) {
        $uri = '/';
        while ($k <= $i) {
                $uri .= $parts[$k];
                if ($k != (sizeof($parts)-1)) $uri .= '/';
                $k++;
         }
          if (($index && is_dir($_SERVER['DOCUMENT_ROOT'].$uri) && is_file($_SERVER['DOCUMENT_ROOT'].$uri.$indexname) 
        || !$index 
        || !is_dir($_SERVER['DOCUMENT_ROOT'].$uri)) && $parts[$i] != $ifIndex) {
            $breadcrumb .= "<a href=\"$uri\">";
            if ($hidextra) {
                $breadcrumb .= rtrim(preg_replace("/\?.*$/", '', ucwords(str_replace($array," ",$parts[$i]))), $extension);
            }
            else {
                $breadcrumb .= rtrim(ucwords($parts[$i]), $extension);
            }
            $breadcrumb .= '</a>';
        }
        else {
            $breadcrumb .= ucwords(str_replace($array," ",$parts[$i]));
        }

          if (isset($parts[($i+1)])) {
            $breadcrumb .= $division;
        }
          $k = 1;
    }
    return $breadcrumb;
}

Hello everyone,

I'm exporting some mysql data to a text file. The data can be selected by checkboxes from a table.

I want to format the text that will be in text file. How do I do that?

This is my code:
Code: [Select]
<?php
if ($_POST['exporttxt']) {
for($i=0;$i<count($_POST['checkbox']);$i++){
   $export_id = $checkbox[$i];
$text = mysql_query("SELECT code FROM tickets WHERE id='$export_id'");
$text = mysql_fetch_assoc($text);
$text = $text["code"];
$filename = "export";
$filedate = date("Y-m-d");
$fileext = ".txt";
$fileall = $filename.$filedate.$fileext;
ob_end_clean();
    header("Content-Type: application/octet-stream");
header("Content-disposition: attachment;filename=\"$fileall\"");
   header("Content-Type: application/force-download");

    header("Content-Type: application/download");
    header("Content-Description: File Transfer");
    header("Content-Length: ".strlen($output).";\n");



echo($text);


}
}

exit();

?>

The data that will be exported are numbers containing of 16 digits. After every number I want to have a line-break. Also if possible I would like to have a space after 4 digits for every number, example:

Number non-formatted: 1234567891234567 Number formatted: 1234 5678 9123 4567

How can I do that?
