Count Files in a Directory

[Kristopher]

Is there a way to get the number of files in a given directory without looping it?

[TheDefender]

I don't think there is any predefined function to load directory contents into an array to count. You need to opendir(), then loop through the readdir() to load each into an array, and then do a count on the array... or something along those lines. Basically, the point I am making is that there is no PHP function to do this. (that I know of) But, I am always open to learning from the 1000+ post regulars. 😉

With PHP5 comes the invention of [man]scandir/man!

Until then, try this:

<?php
function scandir($dir=".",$sort=0,$type=0) {
  if ($sort!==1 && $sort!==0) return "error_sort";
  if (is_dir($dir) === FALSE) return "error_dir";
  $dirlist = "";
  $filelist = "";
  if ($handle = opendir($dir)) {
    while (false !== ($file = readdir($handle))) {
      if ($file != "." && $file != "..") {
        if (is_dir($file) === TRUE && ($type > 0)) {
          $dirlist[] = $file;
          if ($sort === 0){
            sort($dirlist);
          } else {
            rsort($dirlist);
          }
          $scandir["dir"] = $dirlist;
        }
        if (is_dir($file) === FALSE && $type !== 1) {
          $filelist[] = $file;
          if ($sort === 0){
            sort($filelist);
          } else {
            rsort($filelist);
          }
          $scandir["file"] = $filelist;
        }
      }
    }
    closedir($handle);
    return $scandir;
  }
}

//example use:

if (isset($_GET['dir'])) {
  $dir = $_GET['dir'];
} else {
  $dir = ".";
};
//  returns all files in the directory you specify:
$scanfile = scandir($dir,0,0);
//  returns all directories in the directory you specify:
$scandir = scandir($dir,0,1);
//  returns all files and directories in the directory you specify:
$scanboth = scandir($dir,0,2);
//  returns all files in the directory you specify in reverse order:
$scanrev = scandir($dir,1);
?>

That's nice BuzzLy. Good function. Kristopher, I would probably name it something other than scandir() though, to remove any confusion from the PHP5 scandir() function...

[BuzzLY]

Well... the idea was to create an identical function, so that when PHP5 comes out, the built-in function takes over. But, as most things do, it evolved a bit, into something more than what scandir() does. 🙂

So, yeah, I'd rename it to something different.

[TheDefender]

They always do don't they BuzzLy?

You submitting it to the to the PHP developers for inclusion in PHP5 or what? 😃

[BuzzLY]

Heh... their scandir() function is a lot more thorough than mine, I'd imagine. For one, PHP5's kicks off a warning. Mine doesn't. 😃
