如何从坏结果和网址修复痕迹

Question

我已附上面包屑，现在正在运行。但如何整理结果才能发挥作用。

此代码

<?php


$crumbs = explode("/",$_SERVER["REQUEST_URI"]);

foreach($crumbs as $crumb){
    ucfirst(str_replace(array(".php","_"),array(""," "),$crumb) . ' ');
}

$urls = "http://example.com";

foreach($crumbs as $crumb){

$urls .= "/".$crumb;

echo '<li><a href="'.$urls.'">';
echo $crumb;
echo '</a></li>';

}
?>

，结果是

Home / / pages / contact

如何在家后删除一个斜杠？

和url的结果

http://example.com//pages/contact

我试图修复但仍未解决

Answer 1

添加每个＆＃39;面包屑＆＃39;循环中的数组，然后在循环后内插数组，添加斜杠。

$urls = "http://example.com";

$breadcrumbs = array();

foreach($crumbs as $crumb){    

    $breadcrumbs[] = "<li><a href='$urls/$crumb'>$crumb</a></li>";

}

echo '/'.implode('/',$breadcrumbs);
