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

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);
    }
}
