Example #1 dirname() ����
<?php
echo "1) " . dirname("/etc/passwd") . PHP_EOL; // 1) /etc
echo "2) " . dirname("/etc/") . PHP_EOL; // 2) / (or \ on Windows)
echo "3) " . dirname("."); // 3) .
?>
Note:
dirname() operates naively on the input string, and is not aware of the actual filesystem, or path components such as "..".
Note:
dirname() is locale aware, so for it to see the correct directory name with multibyte character paths, the matching locale must be set using the setlocale() function.
Note:
Since PHP 4.3.0, you will often get a slash or a dot back from dirname() in situations where the older functionality would have given you the empty string.
