Question

I got this error when I am trying to run a simple PhP script via php.exe. The name of the script is gulliver ( no extension), and I type this into my command prompt:

php %Dir%\gulliver 

Here’s the content in the gulliver file:

<?php //***************** Operating Systems parameters  **************************   if ( PHP_OS == 'WINNT' )      define('PATH_SEP', '\\');   else     define('PATH_SEP', '/');  //***************** Defining the Home Directory *********************************   $docuroot =  explode ( PATH_SEP , $_SERVER['PWD'] ); 

The error occured was PHP notice: Undefined index: PWD in %Directory%gulliver.

Any idea how to solve this problem?

Answer 1

I could not find PWD in the manual page for $_SERVER. To find out which indexes are defined use var_dump($_SERVER);

If you need the ‘current working directory’, use the getcwd() function.

PS: Instead of defining your own PATH_SEP, you could use the predefined constant DIRECTORY_SEPERATOR.
