There are several things you could do to optimise the script - but maximum success would make it IO-bound rather than CPU-bound    Calculate rtrim  path       outside the loop  make if   t lt  gt      amp  amp   t lt  gt       the outer test - it doesn t need to stat the path Calculate rtrim  path                t once per loop - inside 2  and taking 1  into account  Calculate explode      B KB MB GB TB PB    once rather than each call

Regarding Johnathan Sampson s Linux example  watch out when you are doing an intval on the outcome of the  du  function  if the size is  2GB  it will keep showing 2GB   Replace     totalSize   intval fgets  io  80      by   strtok fgets  io  80           supposed your  du  function returns the size separated with space followed by the directory file name

Even though there are already many many answers to this post  I feel I have to add another option for unix hosts that only returns the sum of all file sizes in the directory  recursively   If you look at Jonathan s answer he uses the du command  This command will return the total directory size but the pure PHP solutions posted by others here will return the sum of all file sizes  Big difference  What to look out for When running du on a newly created directory  it may return 4K instead of 0  This may even get more confusing after having deleted files from the directory in question  having du reporting a total directory size that does not correspond to the sum of the sizes of the files within it  Why  The command du returns a report based on some file settings  as Hermann Ingjaldsson commented on this post  The solution To form a solution that behaves like some of the PHP-only scripts posted here  you can use ls command and pipe it to awk like this  ls -ltrR  path to dir  awk   print   5   awk  BEGIN sum 0   sum sum   1  END  print sum    As a PHP function you could use something like this  function getDirectorySize   path         if   is dir   path               return 0              path     strval   path         io       popen   quot ls -ltrR   path   awk   print   5   awk  BEGIN sum 0   sum sum   1  END  print sum   quot    r          size     intval  fgets   io  80          pclose   io         return  size

A one-liner solution   Result in bytes    size array sum array map  filesize   glob    dir             Added bonus  you can simply change the file mask to whatever you like  and count only certain files  eg by extension

There are several things you could do to optimise the script - but maximum success would make it IO-bound rather than CPU-bound    Calculate rtrim  path       outside the loop  make if   t lt  gt      amp  amp   t lt  gt       the outer test - it doesn t need to stat the path Calculate rtrim  path                t once per loop - inside 2  and taking 1  into account  Calculate explode      B KB MB GB TB PB    once rather than each call

Even though there are already many many answers to this post  I feel I have to add another option for unix hosts that only returns the sum of all file sizes in the directory  recursively   If you look at Jonathan s answer he uses the du command  This command will return the total directory size but the pure PHP solutions posted by others here will return the sum of all file sizes  Big difference  What to look out for When running du on a newly created directory  it may return 4K instead of 0  This may even get more confusing after having deleted files from the directory in question  having du reporting a total directory size that does not correspond to the sum of the sizes of the files within it  Why  The command du returns a report based on some file settings  as Hermann Ingjaldsson commented on this post  The solution To form a solution that behaves like some of the PHP-only scripts posted here  you can use ls command and pipe it to awk like this  ls -ltrR  path to dir  awk   print   5   awk  BEGIN sum 0   sum sum   1  END  print sum    As a PHP function you could use something like this  function getDirectorySize   path         if   is dir   path               return 0              path     strval   path         io       popen   quot ls -ltrR   path   awk   print   5   awk  BEGIN sum 0   sum sum   1  END  print sum   quot    r          size     intval  fgets   io  80          pclose   io         return  size
