Php mkdir: create multi-level Directory instance code

First, we will introduce the mkdir () function.

Mkdir ($ path, 0777, true );

The first parameter is required. It indicates the path of the multi-level directory to be created;

The second parameter: sets the directory permission. The default value is 0777, which means the maximum possible access;

The third parameter: true indicates that multi-level directories can be created.

Mkdir ($ dir, $ mode); however, it can only create one directory at a time, that is, it cannot create multi-level directories at a time, as shown below

Mkdir ('A'); // only one aa directory can be created.

Mkdir ('AA/bb/CC'); // if the aa/bb directory exists, you can create a cc Directory. Otherwise, an error is returned. If you want to create multiple directories, see the following code.

Example code (supports creating a Chinese directory ):

The code is as follows:

Copy code

<? Php   Header ("Content-type: text/html; charset = utf-8 "); // Multi-level directory to be created $ Path = "dai/php learning "; // Check whether a directory exists. If yes, a prompt is displayed. If no directory exists, create a directory. If (is_dir ($ path )){ Echo "Sorry! The Directory ". $ path." already exists! "; } Else { // The third parameter is "true", indicating that multi-level directories can be created. iconv prevents Chinese Directory garbled characters $ Res = mkdir (iconv ("UTF-8", "GBK", $ path), 0777, true ); If ($ res ){ Echo "directory $ path created successfully "; } Else { Echo "directory $ path creation failed ";   }  }   ?>

Let's look at an example of Recursive directory creation.

I have compiled two methods for recursively creating directories for your reference. Thank you!

The code is as follows:

Copy code

<? Php /* * Mkdir ($ dir, $ mode) * Recursive directory creation in PHP */ Function mkdirs ($ dir, $ mode = 0777) { If (is_dir ($ dir) | @ mkdir ($ dir, $ mode )){ Return true;     } If (! Mkdirs (dirname ($ dir), $ mode )){ Return false;     } Return @ mkdir ($ dir, $ mode ); } Function mkdirs ($ dir, $ mode = 0777) { $ DirArray = explode ("/", $ dir ); $ DirArray = array_filter ($ dirArray );    $ Created = ""; Foreach ($ dirArray as $ key => $ value ){ If (! Empty ($ created )){ $ Created. = "/". $ value; If (! Is_dir ($ created )){ Mkdir ($ created, $ mode );             } } Else { If (! Is_dir ($ value )){ Mkdir ($ value, $ mode );             } $ Created. = $ value;         }     } } ?> // Code application instance $ Path = "abc/ff/ss /"; Mkdirs ($ path, $ mode = 0777 );
