从php中的url中提取文件夹名称

Question

我遇到了一个麻烦，我怎么能从网址中提取文件夹名称 示例 - http://localhost/posts/author/FOLDER_NAME/live/?red=home
我想回复FOLDER_NAME到我的网页

<?php echo $name; ?>

Answer 1

您可以按“/”分解字符串并获取正确的元素：

print explode("/", "http://localhost/posts/author/FOLDER_NAME/live/?red=home")[5];

Answer 2

有几种方法可以满足您的需求，一种简单的方法就是使用preg_replace：

$url = "http://localhost/posts/author/FOLDER_NAME/live/?red=home"
$folder = preg_replace('%.*author/(.*?)/live.*%', '$1', $url);
echo $folder ;

输出：

FOLDER_NAME

根据您的评论更新：

$url = "http://localhost/posts/author/FOLDER_NAME?red=home"; 
$folder = preg_replace('%.*author/(.*?)\?.*%', '$1', $url);
echo $folder ;

输出：

FOLDER_NAME
