PHP getcwd – Retrieve Current Working Directory
The article explains the PHP getcwd() function, its return values, permission considerations on Unix variants, and provides a clear code example demonstrating how to obtain and change the current working directory using echo and chdir.
The PHP function getcwd() returns the current working directory as a string, or FALSE on failure.
It behaves like the Unix pwd command, but on some Unix variants it may return FALSE if any parent directory lacks read or execute permissions, even when the current directory itself is readable.
Return value: On success, the absolute path of the current directory; on failure, FALSE .
Example:
The example prints the initial directory, changes to the cvs directory, and then prints the new working directory.
