mkdir — Makes directory
$directory,$permissions = 0777,$recursive = false,$context = null
Attempts to create the directory specified by directory.
directoryThe directory path.
permissionsThe permissions are 0777 by default, which means the widest possible access. For more information on permissions, read the details on the chmod() page.
Note:
permissionsis 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
Allows the creation of nested directories specified in the
directory.
contextA context stream resource.
Returns true on success or false on failure.
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.
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...');
}
// ...
