对于一个简单的面包屑来说,这可能有些过分,但值得一试。我记得很久以前当我第一次开始时遇到这个问题,但我从来没有真正解决过它。也就是说,直到我决定现在写这个。:)
我已经尽我所能内联记录了,底部有3个可能的用例。享受!(随时询问您可能遇到的任何问题)
<?php
// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path
function breadcrumbs($separator = ' » ', $home = 'Home') {
// This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values
$path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));
// This will build our "base URL" ... Also accounts for HTTPS :)
$base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';
// Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL)
$breadcrumbs = Array("<a href=\"$base\">$home</a>");
// Find out the index for the last value in our path array
$last = end(array_keys($path));
// Build the rest of the breadcrumbs
foreach ($path AS $x => $crumb) {
// Our "title" is the text that will be displayed (strip out .php and turn '_' into a space)
$title = ucwords(str_replace(Array('.php', '_'), Array('', ' '), $crumb));
// If we are not on the last index, then display an <a> tag
if ($x != $last)
$breadcrumbs[] = "<a href=\"$base$crumb\">$title</a>";
// Otherwise, just display the title (minus)
else
$breadcrumbs[] = $title;
}
// Build our temporary array (pieces of bread) into one big string :)
return implode($separator, $breadcrumbs);
}
?>
<p><?= breadcrumbs() ?></p>
<p><?= breadcrumbs(' > ') ?></p>
<p><?= breadcrumbs(' ^^ ', 'Index') ?></p>
