Description
bool mkdir(
string $directory,
int $permissions = 0777,
bool $recursive = false,
resourcenull $context = null
)
Parameters
-
directory
-
The directory path.
TipA URL can be used as a
filename with this function if the fopen wrappers have been enabled.
See fopen for more details on how to specify the
filename. See the Supported Protocols and Wrappers for links to information
about what abilities the various wrappers have, notes on their usage,
and information on any predefined variables they may
provide.
-
permissions
-
The permissions are 0777 by default, which means the widest possible
access. For more information on permissions, read the details
on the chmod page.
Note:
permissions is ignored on Windows.
Note that you probably want to specify the permissions as an octal number,
which means it should have a leading zero. The permissions is also modified
by the current umask, which you can change using
umask.
-
recursive
-
If true, then any parent directories to the directory specified will
also be created, with the same permissions.
-
context
-
A context stream
resource.
Return Values
Returns true on success or false on failure.
Note:
If the directory to be created already exists, that is considered an error
and false will still be returned. Use is_dir or
file_exists to check if the directory already exists
before trying to create it.
Errors/Exceptions
Emits an E_WARNING level error if the directory
already exists.
Emits an E_WARNING level error if the relevant
permissions prevent creating the directory.
Examples
Example #1 mkdir example
<?php
mkdir("/path/to/my/dir", 0700);
?>
Example #2 mkdir using the recursive parameter
<?php
// Desired directory structure
$structure = './depth1/depth2/depth3/';
// To create the nested structure, the $recursive parameter
// to mkdir() must be specified.
if (!mkdir($structure, 0777, true)) {
die('Failed to create directories...');
}
// ...
