PHP display current server path
提问by Satch3000
I need to setup a path in my php but I currently don't know the path.
我需要在我的 php 中设置一个路径，但我目前不知道该路径。
I need to configure the paths the the uploads directory
我需要配置上传目录的路径
Should look like this below:
应该如下所示：
/srv/www/uploads/
My uploads.php file is in the root...so
我的uploads.php 文件在根目录中......所以
www/uploads/ ???
Is there anyway that I could get php to tell me my current path?
无论如何，我可以让 php 告诉我我当前的路径吗？

- To get your current working directory:
getcwd()(documentation) - To get the document root directory:
$_SERVER['DOCUMENT_ROOT'] - To get the filename of the current script:
$_SERVER['SCRIPT_FILENAME']
- 为了让您的当前工作目录：
getcwd()（文档） - 获取文档根目录：
$_SERVER['DOCUMENT_ROOT'] - 获取当前脚本的文件名：
$_SERVER['SCRIPT_FILENAME']
回答by Gregory R.
echo $_SERVER["DOCUMENT_ROOT"];
'DOCUMENT_ROOT' The document root directory under which the current script is executing, as defined in the server's configuration file.
'DOCUMENT_ROOT' 当前脚本在其下执行的文档根目录，如服务器配置文件中所定义。

You can also use the following alternative realpath.
您还可以使用以下替代realpath。
Create a filecalled path.php
创建一个名为path.php的文件
Put the following codeinside by specifying the name of the created file.
通过指定创建的文件的名称将以下代码放入其中。
<?php
echo realpath('path.php');
?>
A php file that you can move to all your folders to always have the absolute path from where the executed file is located.
一个可以移动到所有文件夹的 php 文件，以始终具有执行文件所在位置的绝对路径。

php can call command line operations so
php 可以调用命令行操作，所以
echo exec("pwd");
