PHP简单修改/修正

Question

我从某人那里得到了这段代码，创建动态面包屑几乎是完美的，但是有一点小故障，因为它在面包屑之前回显了两个分隔线：

$crumbs = explode("/",$_SERVER["REQUEST_URI"]);
foreach($crumbs as $crumb){
    echo ucfirst(str_replace(array(".php","_"),array(""," "),'>' . $crumb));
}

它回显：

“>>内容>通用>文件”

我想要它做什么看起来像是

“content>common>1”，

如果有人能告诉我如何为数组中除最后一个（文件）之外的所有项目添加链接，我将不胜感激？

非常感谢大家，这个网站通过示例对我学习 php 帮助很大！

也许这样的事情会做：

//去掉空的部分
$crumbs = array_filter($crumbs);

$result = array();
$path = '';
foreach($crumbs as $crumb){
    $path .= '/' . $crumb;
    $name = ucfirst(str_replace(array(".php","_"),array(""," "), $crumb));
    $result[] = "<a href=\"$path\">$name</a>";

}

echo implode(' > ', $result);

已更新

$result = array();
$path = '';
$num = count($crumbs);
for ($j=0; $j<$num; $j++) {
    $crumb = $crumbs[$j];
    if ($crumb == '') {
        continue;   
    }
    $path .= '/' . $crumb;
    $name = ucfirst(str_replace(array(".php","_"),array(""," "), $crumb));
    if ($j < ($num - 1)) {
        $result[] = "<a href=\"$path\">$name</a>";
    } else {
        $result[] = $name;
    }
}

echo implode(' > ', $result);
