PHP 循环检查创建目录 ，0777

function ckDir($path){ $path = is_dir($path) ? $path:dirname($path); $folderArr = explode("/",$path); $dir = $comma = ""; foreach($folderArr as $folder){ $dir .= $comma.$folder; $comma = "/"; if($dir == "." || $dir == "..") continue; if(!is_dir($dir)) mkdir($dir,0777); } }

2011-08-20 更正：上面这个写的太复杂了，下面这个精简版的：

function MkFolder($path){
  if(!is_readable($path)){
    MkFolder( dirname($path) );
    if(!is_file($path)) mkdir($path,0777);
    }
}
