我在本地电脑上有一个网站,我用Wamp服务器运行我的网站。
网站的 URL 是 < energy> http://localhost/mywebsite/ 网站的 URL
我把一个PHP文件放入我网站上的文件夹“强势”网站/构件/添加/文件/添加/添加/添加.php
文件的实际路径是 c:\wampwwwmywebsite 构件添加文件add.php 。
我要在我的文件中显示路径<强>c:wamp:wwwmywebsite 。
如何得到它? 将来当我将网站移到别的地方时, 我不需要手动更改路径。 它必须自动更新 。 是否有功能可以使用?
e. 例如,如果我将我的网址移动到 < 坚固> 网站/ demo < / 坚固 >,路径将是 < 坚固 > C:wampwwwmywebsitememo 。
我希望这一点能够清楚理解,我不想在那里展示“强势”的路径:http://localhost/mywebsite 。
有人能帮我吗?
"http://php.net/manual/en/reservables.server.php" rel="nofollow" >$_SERVER阵列 应该有您想要的信息。 例如 :
$_SERVER[ DOCUMENT_ROOT ]
这将为 PHP 服务器配置文档根 。 对于您来说, 我相信是 < code> c: wampwww 。 您也可以使用 :
$_SERVER[ SCRIPT_FILENAME ]
这将是当前运行脚本的绝对路径。 还有一些 < a href=" http:// php. net/ manual/ en/ language. constats. prefed. php" rel=“ nofollow” > 魔术常数 < /a > 包含有用信息, 特别是如果您在网络服务器外也有 PHP 脚本运行的话 。 (背景任务等 )
使用 :
$_SERVER[ DOCUMENT_ROOT ];
或
Perhaps you want: dirname(__FILE__)
您可以使用此代码
str_replace($_SERVER[ DOCUMENT_ROOT ], , $_SERVER[ SCRIPT_FILENAME ])
或选择
str_replace($_SERVER[ DOCUMENT_ROOT ], , dirname(__FILE__));
str_replace($_SERVER[ DOCUMENT_ROOT ], , __DIR__); // works only in php > 5.3
