用于创建文件夹的PHP代码

my project needs folder to be created whenever user registers using userid inside upload folder so i'm using below lines but its not creating any new folder inside upload folder with userid

       $userid = $this->db->insert_id();
       $path   = './upload/'.$userid;
       if(!is_dir($path)) //create the folder if it's not already exists
       {
          mkdir($path,0755,TRUE);
       } 

PS: i am using wamp server and ci..

thanks

you should try this code

chmod('./upload/', 0777);
$path   = './upload/'.$userid;
if (!is_dir($path)) { //create the folder if it's not already exists
    mkdir($path, 0755, TRUE);
}

upload dir path for CI

$path   = './upload/'.$userid;

You should use a full path to create a directory and also the upload folder should have the right permissions to create dir's and files in it.
