PHP 痕迹导航数组，链接未满

Question

我为面包屑使用以下代码：<?phpclass 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 $this->breadcrumb;   }} ?>我这样称呼它：<?php$breadcrumb = new Breadcrumb();  echo $breadcrumb->build(array(  $pageTitle => 'about',    'More' => 'more.php'  )); ?>页面标题是每个页面顶部的变量。输出是正确的，并显示：首页 / 关于 / 更多 但是，每个上的链接如下所示：Home: example.orgAbout: example.org/aboutMore: example.org/more.php我正在寻找这样的输出：example.org/about/more.php

您可以在循环中连接链接...

$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;

    }

}
