实时服务器上存在文件警告

Warning: mkdir() [function.mkdir]: File exists in /home/content/xx/xxxxxxxx/html/xxxx/xxxx/action.php on line xx

This warning is on live server. But in localhost there is no warning.

I am trying :

if(!file_exists($path)){
   mkdir($path);
}

At first check your $path. Is it a directory location?

If it is, you wanted to check a directory is exists or not so

Use:

if(!is_dir($path)){
   mkdir($path);
}

If directory is not created.

Check is there your directory create permission!
