PHP counts the number of files in a directory and subdirectory

I need to get the total number of JPG files in the specified directory, including ALL of its subdirectories. There are no subdirectories.

The structure is as follows:

dir1 /
2 files  
   subdir 1 /
       8 files

total dir1 = 10 files

dir2 / 
    5 files  
    subdir 1 / 
        2 files  
    subdir 2 / 
        8 files

total dir2 = 15 files

I have this function, which does not work fine, since it only considers files in the last subdirectory, and the amount is 2 times larger than the actual number of files. (prints 80 if I have 40 files in the last subdirectory)

public function count_files($path) { 
global $file_count;

$file_count = 0;
$dir = opendir($path);

if (!$dir) return -1;
while ($file = readdir($dir)) :
    if ($file == '.' || $file == '..') continue;
    if (is_dir($path . $file)) :
        $file_count += $this->count_files($path . "/" . $file);
    else :
        $file_count++;
    endif;
endwhile;

closedir($dir);
return $file_count;
}
