disk_total_space -- Devuelve el tamaÃ±o total de un directorio

DescripciÃ³n

float disk_total_space ( string directorio )

Dada una cadena que contiene un directorio, esta funciÃ³n devolverÃ¡ el nÃºmero total de bytes en el sistema de archivos o particiÃ³n de disco correspondiente.

Ejemplo 1. Ejemplo de disk_total_space()

<?php // $df contiene el numero total de bytes disponible en "/" $df = disk_total_space("/"); // En Windows: disk_total_space("C:"); disk_total_space("D:"); ?>

Nota: Esta funcion no funcionara con ficheros remotos ya que el fichero a examinar tiene que estar disponible desde el sistema de ficheros del servidor.

My first contribution. Trouble is the sum of the byte sizes of the files in your directories is not equal to the amount of disk space consumed, as andudi points out. A 1-byte file occupies 4096 bytes of disk space if the block size is 4096. Couldn't understand why andudi did $s["blksize"]*$s["blocks"]/8. Could only be because $s["blocks"] counts the number of 512-byte disk blocks not the number of $s["blksize"] blocks, so it may as well just be $s["blocks"]*512. Furthermore none of the dirspace suggestions allow for the fact that directories are also files and that they also consume disk space. The following code dskspace addresses all these issues and can also be used to return the disk space consumed by a single non-directory file. It will return much larger numbers than you would have been seeing with any of the other suggestions but I think they are much more realistic:





<?php


function dskspace($dir)


{ 


   $s = stat($dir);


   $space = $s["blocks"]*512;


   if (is_dir($dir))


   { 


     $dh = opendir($dir); 


     while (($file = readdir($dh)) !== false)


       if ($file != "." and $file != "..") 


         $space += dskspace($dir."/".$file); 


     closedir($dh);


   } 


   return $space; 


}


?>

To find the total size of a file/directory you have to differ two situations:

(on Linux/Unix based systems only!?)



you are interested:

1) in the total size of the files in the dir/subdirs

2) what place on the disk your dir/subdirs/files uses



- 1) and 2) normaly differs, depending on the size of the inodes

- mostly 2) is greater than 1) (in the order of any kB)

- filesize($file) gives 1)

- "du -ab $file" gives 2)



so you have to choose your situation!



on my server I have no rights to use "exec du" in the case of 2), so I use:

  $s = stat($file);

  $size = $s[11]*$s[12]/8);

whitch is counting the inodes [12] times the size of them in Bits [11]



hopes this helps to count the used disk place in a right way... :-)

I just did the simple thing -





<?php


function du($dir)


{


    $du = popen("/usr/bin/du -sk $dir", "r");


    $res = fgets($du, 256);


    pclose($du);


    $res = explode(" ", $res);


    


    return $res[0];


}


?>
