dirname
(PHP 4, PHP 5)
dirname — Returns directory name component of path
Description
string dirname
( string $path
)
Parameters
-
path
-
A path.
On Windows, both slash (/) and backslash
(\) are used as directory separator character. In
other environments, it is the forward slash (/).
Return Values
Returns the name of the directory. If there are no slashes in
path
, a dot ('.') is returned,
indicating the current directory. Otherwise, the returned string is
path
with any trailing
/component removed.
Examples
Example #1 dirname() example
<?php
$path = "/etc/passwd";
$file = dirname($path); // $file is set to "/etc"
?>
Notes
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.
Check the following change example:
Load balance : Server 03
