消除php中url字符串的最后一部分 - Eliminating last part of url string in php

Eliminating last part of url string in php

我有一个url字符串，如下所示：

http://example.com/sfm?dir=uploads/sfm/root/folder5/file.zip

echo $_GET['extract']输出：uploads/sfm/root/folder5/file.zip我如何剥离最后一个文件.zip，以便

echo $_GET['extract']输出：uploads/sfm/root/folder5/

使用以下代码：

$String = $_GET['extract'];
$Words = explode('/', $String);
echo end($Words );

echo dirname($_GET['extract'])."/";

尝试：

$url = "uploads/sfm/root/folder5/file.zip";
$urlArr= explode("/",$url);
array_pop($urlArr);
echo implode("/",$urlArr);

也许这有效：

echo substr((string)$_GET['extract'],26);

尝试这个

<?php
 $ss ="uploads/sfm/root/folder5/file.zip";
 $vv  = explode('/',$ss);
array_pop($vv);
$mm =implode('/',$vv);
print_r($mm);
 ?>
