PHP getcwd – Retrieve Current Working Directory

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:

<?php
// current directory
echo getcwd() . "
";
chdir('cvs');
echo getcwd() . "
";
?>

The example prints the initial directory, changes to the cvs directory, and then prints the new working directory.
