(PHP 4, PHP 5, PHP 7)
mkdir — Makes directory
$pathname
[, int $mode = 0777
[, bool $recursive = FALSE
[, resource $context
]]] ) : boolAttempts to create the directory specified by pathname.
pathnameThe directory path.
modeThe mode is 0777 by default, which means the widest possible access. For more information on modes, read the details on the chmod() page.
Note:
modeis ignored on Windows.
Note that you probably want to specify the mode as an octal number, which means it should have a leading zero. The mode is also modified by the current umask, which you can change using umask().
recursive
Allows the creation of nested directories specified in the
pathname.
contextNote: Context support was added with PHP 5.0.0. For a description of
contexts, refer to Streams.
Returns TRUE on success or FALSE on failure.
Example #1 mkdir() example
<?php
mkdir("/path/to/my/dir", 0700);
?>
Example #2 mkdir() using the recursive parameter
<?php
// Desired folder 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 folders...');
}
// ...
?>
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.
Note: When safe mode is enabled, PHP checks whether the directory in which the script is operating has the same UID (owner) as the script that is being executed.
