我的URL可能在下面，
1( www.steptoinstall.com
2( www.steptoinstall.com/folder1
3( www.steptoinstall.com/folder1/index.php
4( www.steptoinstall.com/folder1/folder2
5( www.steptoinstall.com/folder1/folder2/
6( www.steptoinstall.com/folder1/folder2/index.php
7( www.steptoinstall.com/folder1/folder2/index.php？id=12
但我想要最后一个文件夹名，比如
1( 无
2( 折页1
3( 折页1
4( 折页2
5( 折页2
6( 折页2
7( 折页2
我使用了以下内容，但没有用。
<?php
$url = $_SERVER['REQUEST_URI'];
print_r(dirname($url));
?>
如何在PHP中而不是在.htaccess中获得此输出？
$path = 'www.steptoinstall.com/folder1/folder2/';
$folders = explode('/', $path);
$i = 0;
foreach($folders as $folder) {
if (strpos($folder, '.') !== FALSE || empty($folder)) {
unset($folders[$i]);
}
$i++;
}
$what_we_need = end($folders);
echo $what_we_need;
很抱歉我的第一个答案被取消了，这应该会有问题。
也许这对你的有用
<?php
$urls = array(
'http://www.steptoinstall.com',
'http://www.steptoinstall.com/folder1',
'http://www.steptoinstall.com/folder1/folder2/index.php?id=12'
);
// The Function for your work
function getFolder($url) {
$res = parse_url($url);
if(!isset($res['path'])) {
return false;
}
$res = explode('/',$res['path']);
$out = false;
foreach($res as $p) {
if(!empty($p) && strpos($p,'.')===false) $out = $p;
}
return $out;
}
// Testing
foreach($urls as $url) {
var_dump(getFolder($url));
}
如果我正确理解您的问题，您可以使用以下自定义函数
function get_arg() {
$arguments = array();
$path = $_SERVER['REQUEST_URI'];
if (isset($path)) {
$arguments = explode('/', $path);
}
$url_len = count($arguments);
return ($arguments[$url_len - 2]) ? $arguments[$url_len - 2] : 'none';
}
希望这对你有帮助。
我使用了正则表达式：
<?php
$data = array(
'www.steptoinstall.com',
'www.steptoinstall.com/folder1',
'www.steptoinstall.com/folder1/index.php',
'www.steptoinstall.com/folder1/folder2',
'www.steptoinstall.com/folder1/folder2/',
'www.steptoinstall.com/folder1/folder2/index.php',
'www.steptoinstall.com/folder1/folder2/index.php?id=12',
);
foreach($data as $url)
{
print $url." ".get_folder($url)."'n";
}
function get_folder($url)
{
$url = preg_replace('/(.*)'/.*'..*/', '$1', $url);
$url = preg_replace('/'/$/', '$1', $url);
$matches = array();
if (preg_match('/.*'/(.*)/', $url, $matches))
{
return $matches[1];
}
return '';
}
输出：
www.steptoinstall.com
www.steptoinstall.com/folder1 folder1
www.steptoinstall.com/folder1 folder1
www.steptoinstall.com/folder1/folder2 folder2
www.steptoinstall.com/folder1/folder2 folder2
www.steptoinstall.com/folder1/folder2 folder2
www.steptoinstall.com/folder1/folder2 folder2
这里可能有一个问题：很难区分"www.steptoinstall.com/folder1"answers"www.steetoinstall.com/folder.index.php"——如果有一个SEF url没有.php结尾。
