how to "trim" breadcrumbs links

[andreiviziru]

so i have the following script:

<?php
/**

 */

class breadcrumbs{

    /*
     * @string $breadcrumbs
     */
    public $breadcrumbs;

    /*
     * @string $pointer
     */
    private $pointer = '&raquo;';

    /*
     * @string $url
     */
    private $url;

    /*
     * @array $parts
     */
    private $parts;


    /*
     * @constructor - duh
     *
     * @access public
     *
     */
    public function __construct()
    {
        $this->setParts();
        $this->setURL();
        $this->breadcrumbs = '<a class="bc" href="'.$this->url.'">Start</a>';
    }


    /*
     *
     * @set the base url
     *
     * @access private
     *
     */
    private function setURL()
    {
        $protocol = $_SERVER["SERVER_PROTOCOL"]=='HTTP/1.1' ? 'http' : 'https';
        $this->url = $protocol.'://'.$_SERVER['HTTP_HOST'];
    }


    /*
     * @set the pointer 
     *
     * @access public
     *
     * @param string $pointer
     * 
     */
    public function setPointer($pointer)
    {
        $this->pointer = $pointer;
    }


    /**
     *
     * @set the path array
     *
     * @access private
     *
     * @return array
     *
     */
    private function setParts()
    {
        $parts = explode('/', $_SERVER['REQUEST_URI']);
        array_pop($parts);
        array_shift($parts);
    $this->parts = $parts;
    }


    /**
     *
     * @create the breadcrumbs
     *
     * @access public
     *
      */
    public function crumbs()
    {
        foreach($this->parts as $part)
        {
            $this->url .= "/$part";
            $this->breadcrumbs .= " $this->pointer ".'<a class="bc" href="'.$this->url.'">'.strtoupper(str_replace('_', ' ', $part)).'</a>';
        }
    }
} /*** end of class ***/

?>

and the script is called like this:

<?php
/*** a new breadcrumbs object ***/
$bc = new breadcrumbs;

/*** set the pointer if you like ***/
$bc->setPointer('>');

/*** create the trail ***/
$bc->crumbs();

/*** output ***/
echo $bc->breadcrumbs;
?>

so i called this in my pages and i have the following structure:
/games/action/games/name_of_the_game
and the script displays the following:
Start>GAMES>ACTION>GAMES>NAME OF THE GAME
i need somehow to "trim" the "GAMES" links. how can i achieve that?

I use the CodeIgniter framework and here is the code for the function that they use:

function character_limiter($str, $n = 500, $end_char = '…')
{
    if (strlen($str) < $n)
    {
        return $str;
    }

    $str = preg_replace("/\s+/", ' ', str_replace(array("\r\n", "\r", "\n"), ' ', $str));

    if (strlen($str) <= $n)
    {
        return $str;
    }

    $out = "";
    foreach (explode(' ', trim($str)) as $val)
    {
        $out .= $val.' ';

        if (strlen($out) >= $n)
        {
            $out = trim($out);
            return (strlen($out) == strlen($str)) ? $out : $out.$end_char;
        }
    }
}

It should work if you edit your line 115 and replace $part with character_limiter($part, 10)

got it, i tweaked a little the code from line 110 to look like this

    public function crumbs()
    {
        foreach($this->parts as $part)
        {
            if ($part!='games') {
            $this->url .= "/games/$part";
            $repl = array('_', '...');
            $this->breadcrumbs .= " $this->pointer ".'<a class="bc" href="'.$this->url.'">'.strtoupper(str_replace($repl, ' ', $part)).'</a>';
            }
        }
    }
