------------ lixlpixel recursive PHP functions -------------
recursive_directory_size( directory, human readable format )

PHP has to have the rights to read the directory you specify

if you choose to get human readable format,
the function returns the filesize in bytes, KB and MB
------------------------------------------------------------
to use this function to get the filesize in bytes, write:
