PHP面包屑数组，链接未满

对于面包屑，我使用以下代码：

<?php

class Breadcrumb
{
   private $breadcrumb;
   private $separator = ' / ';
   private $domain = 'example.org';

   public function build($array)
   {
      $breadcrumbs = array_merge(array('Home' => ''), $array);
      $count = 0;
      foreach($breadcrumbs as $title => $link) {
         $this->breadcrumb .= '
         <span itemscope="" itemtype="https://schema.org/BreadcrumbList">
            <a href="'.$this->domain. '/'.$link.'" itemprop="url">
               <span itemprop="title">'.$title.'</span>
            </a>
         </span>';

         $count++;
         if($count !== count($breadcrumbs)) {
            $this->breadcrumb .= $this->separator;
         }
      }
      return $this->breadcrumb;
   }
}

 ?>

我正在寻找这样的输出：example.org/about/more.php

多谢各位

您可以在循环过程中连接链接

$bclink = '';
foreach($breadcrumbs as $title => $link) {
    if ($link != '') {
        $bclink .= '/' . $link;
    }
    $this->breadcrumb .= '
        <span itemscope="" itemtype="https://schema.org/BreadcrumbList">
            <a href="'.$this->domain.$bclink.'" itemprop="url">
                <span itemprop="title">'.$title.'</span>
            </a>
        </span>';

    $count++;
    if($count !== count($breadcrumbs)) {
        $this->breadcrumb .= $this->separator;
    }
}

$bclink=''；
foreach（$title=>$link的面包屑）{
如果（$link！=''）{
$bclink.='/'.$link；
}
$this->breadcrumb.='
';
$count++；
如果（$count！==count（$breadcrumbs））{
$this->breadcrumb.=$this->separator；
}
}

您能用about/more.php替换more.php吗？是的，但我想看看除了键入以外是否还有其他解决方案？

Home: example.org
About: example.org/about
More: example.org/more.php

$bclink = '';
foreach($breadcrumbs as $title => $link) {
    if ($link != '') {
        $bclink .= '/' . $link;
    }
    $this->breadcrumb .= '
        <span itemscope="" itemtype="https://schema.org/BreadcrumbList">
            <a href="'.$this->domain.$bclink.'" itemprop="url">
                <span itemprop="title">'.$title.'</span>
            </a>
        </span>';

    $count++;
    if($count !== count($breadcrumbs)) {
        $this->breadcrumb .= $this->separator;
    }
}
