Return total number of files within a folder using PHP

Question

Is there a better/simpler way to find the number of images in a directory and output them to a variable?

function dirCount($dir) {
  $x = 0;
  while (($file          


        

Answer 1

Check out the Standard PHP Library (aka SPL) for DirectoryIterator:

$dir = new DirectoryIterator('/path/to/dir');
foreach($dir as $file ){
  $x += (isImage($file)) ? 1 : 0;
}

(FYI there is an undocumented function called iterator_count() but probably best not to rely on it for now I would imagine. And you'd need to filter out unseen stuff like . and .. anyway.)

Answer 2

Your answer seems about as simple as you can get it. I can't think of a shorter way to it in either PHP or Perl.

You might be able to a system / exec command involving ls, wc, and grep if you are using Linux depending how complex isImage() is.

Regardless, I think what you have is quite sufficient. You only have to write the function once.

Answer 3

I use the following to get the count for all types of files in one directory in Laravel

   $dir = public_path('img/');
    $files = glob($dir . '*.*');

    if ( $files !== false )
    {
        $total_count = count( $files );
        return $totalCount;
    }
    else
    {
        return 0;
    }

Answer 4

i do it like this:

$files = scandir($dir);
$x = count($files);
echo $x;

but it also counts the . and ..
