Failing to create folder in /Var/www/html from file.php - php

Question

I have a AWS EC2 server with phpMyAdmin to manage it.
Everything is working correctly but I would like to be able to create another folder in the /var/www/html directory to add files..
This is my code but it just keeps returning the error to me! any ideas??
// STEP 2.2 Create a folder in server to store posts'pictures
$folder = "/var/www/html/bloggerFiles/Posts/" . $id;
if(!file_exists($folder)){
if (!mkdir($folder, 0777, true)) {//0777
die('Failed to create folders...');
}
}
I would normally create that folder in the terminal by using sudo mkdir, but when I add sudo Nothing works!
Any help is appreciated!
Thanks in advance.

Make sure the folder(s) you are accessing are set to read and write folder permissions, then use this function:
function newFolder($path, $perms)
$path = str_replace(' ', '-', $path);
$oldumask = umask(0);
mkdir($path, $perms); // or even 01777 so you get the sticky bit set (0777)
umask($oldumask);
return true;
}
This fixed it for me.
You can create new folder doing this: newFolder('PathToFolder/here', 0777);
EDIT: Please have a look at: https://www.youtube.com/watch?v=7mx2XOFBp8M
EDIT: Also have a look at http://php.net/manual/en/function.mkdir.php#1207
EDIT: Storing functions in classes and safely use the function
class name_here
{
public function newFolder($path, $perms, $deny_if_folder_exists){
$path = 'PATH_TO_POSTS/'.$path; // This is for setting the root to PATH TO POSTS
$path = str_replace('../', '', $path); // Deny the path to go out of var/www/html/PATH_TO_POSTS/$path
if( $deny_if_folder_exists === true ){
if(file_exists($path)){return false;}
$old_umask = umask(0);
mkdir($path, $perms);
umask($old_umask);
}elseif( $deny_if_folder_exists === false ){
$old_umask = umask(0);
mkdir($path, $perms);
umask($old_umask);
}else{
return false; // Unknown
}
}
}
/* Call the function by doing this: */
$manage = new name_here;
$manage->newFolder('test', 777, true); // Test will appear in /var/www/html/PATH_TO_POSTS/$path, but if the folder exists it will return false and not create the folder.
EDIT: If this file is called from html it will re create the path, so I will it has to be called from /html/
EDIT: How to use the name_here class
/*
How to call the function?
$manage = new name_here; Creates a variable to an object (The class)
$manage->newFolder('FolderName', 0777, true); // Will create a folder to the path,
but this fill needs to be called from the html the root directory is set to the
"PATH_TO_POSTS/" basicly means you cannot do this function from "html/somewhere/form.php",
UNLESS the "PATH_TO_POSTS" is in the same directory as form.php
