breadcrumb.php

<?php

/**
 * Generates a path string for the page header with relevant breadcrumb links.
 *
 * @param $page string  page value of page user is currently accessing (path/format/is/as/such)
 * @return string       breadcrumb string
 */
function getPathStr($page)
{
    $path = explode('/', $page);
    $pathStr = "";

    for ($i = 0; $i < count($path) - 1; $i++) {
        $thisPath = array_slice($path, 0, $i + 1);
        $pathHpl = count($thisPath) > 1 ? implode('/', $thisPath) : $thisPath[0];

        $pathStr .= linkify($path[$i], $pathHpl) . " / ";
    }

    $pathStr .= $path[count($path) - 1];

    return $pathStr;
}

function linkify($input, $link)
{
    return "<a href='/$link'>$input</a>";
}

This is how I utilised the function:

• Pass current path (in this case mc/nether)
• Print result into header with hyperlink CSS
