Upload.php don't upload if limit exceed

[ArshSingh]

i'm using the following code to calculate the size of directory uploads/username but know i want to tell to the script if directory username 's size is greater then 5 gb then upload function echo"Your sapce is full please dlete some files to proceed" so my final question is how do i tell php , if if limit exceeded then upload.php stop uploading files.

<?PHP


CLASS Directory_Calculator {

VAR $size_in;
VAR $decimals;

FUNCTION calculate_whole_directory($directory)
{
IF ($handle = OPENDIR($directory))
{
$size = 0;
$folders = 0;
$files = 0;

WHILE (FALSE !== ($file = READDIR($handle)))
{
IF ($file != "." && $file != "..")
{
IF(IS_DIR($directory.$file))
{
$array = $this->calculate_whole_directory($directory.$file.'/');
$size += $array['size'];
$files += $array['files'];
$folders += $array['folders'];
}
ELSE
{
$size += FILESIZE($directory.$file);
$files++;
}
}
}
CLOSEDIR($handle);
}

$folders++;

RETURN ARRAY('size' => $size, 'files' => $files, 'folders' => $folders);
}

FUNCTION size_calculator($size_in_bytes)
{
IF($this->size_in == 'B')
{
$size = $size_in_bytes;
}
ELSEIF($this->size_in == 'KB')
{
$size = (($size_in_bytes / 1024));
}
ELSEIF($this->size_in == 'MB')
{
$size = (($size_in_bytes / 1024) / 1024);
}
ELSEIF($this->size_in == 'GB')
{
$size = (($size_in_bytes / 1024) / 1024) / 1024;
}

$size = ROUND($size, $this->decimals);

RETURN $size;
}

FUNCTION size($directory)
{
$array = $this->calculate_whole_directory($directory);
$bytes = $array['size'];
$size = $this->size_calculator($bytes);
$files = $array['files'];
$folders = $array['folders'] - 1; // exclude the main folder

RETURN ARRAY('size' => $size,
'files' => $files,
'folders' => $folders);
}
}
?>

show the calculated size in mb

<?PHP

INCLUDE 'models/usersize.php';

/* Path to Directory - IMPORTANT: with '/' at the end */

$directory = "uploads/$loggedInUser->username/"; 

/* Calculate size in: B (Bytes), KB (Kilobytes), MB (Megabytes), GB (Gigabytes) */

$size_in = 'MB';

/* Number of decimals to show */

$decimals = 2;

$directory_size = NEW Directory_Calculator;

/* Initialize Class */

$directory_size->size_in = $size_in;
$directory_size->decimals = $decimals;

// return an array with: size, total files & folders
$array = $directory_size->size($directory);

ECHO "The directory <em>".$directory."</em> has a size of
".$array['size']." ".$size_in.", ".$array['files']." files &
".$array['folders']." folders.";
?>

You need to add the users directory size and the file size for the uploaded file together, if the total is less than 5242880 (5GB) then upload the file, else display error. Example

$directory_size = new Directory_Calculator;
$usersDirectoryFileSize = $directory_size->size($usersDirectoryPath); // calculate users storage space

// NB: make sure $usersDirectoryFileSize['size'] returns the directory size in total bytes, not in english readable format like 1.2GB
if(($usersDirectoryFileSize['size'] + $_FILES['file']['size']) < 5242880)
{
   move_uploaded_file($_FILES['file']['tmp_name'], 'upload/destination/'.$_FILES['file']['name']); // add the file to the users storage directory
}
else
{
   echo 'You have exceeded the 5GB storage space. Please delete some files';
}

Out of curiosity because I've never used php to setup a limit size for some particular directory. Where is the script to do this?

Why don't you just adjust the upload limit size in your php.ini?

Most likely he wants to implement something similar to quota policies for users/members by using php, but not entirly sure
