Several functions for creating directories at unlimited levels in PHP

Creating a directory is something we often encounter when uploading files. If I want to generate a relative directory based on the date and save the file, I need this function. The example code is as follows:

function mkdirs($dir)

{

if(!is_dir($dir)){

if(!mkdirs(dirname($dir))){

return false;}

if(!mkdir($dir,0777)){

return false;}

}

return true;

}

//Test method

$img_path = realpath("../../../upfile/www..php.cn/") .'/'.date("y/m/d/");

mkdirs($img_path);

//function

function mkdir_r($dirname, $rights=0777){

$dirs = explode('/', $dirname);

$dir='';

foreach ($dirs as $part) {

as $part.'/';

if (!is_dir($ dir) && strlen($dir)>0)

                                                                                                                                                                                 );

mkdir_r($path);
