PHP recursively traverses all files in the specified directory and counts the number of files

  2. //Recursive function implements traversing the directory and number of files under the specified file
  4. function total($dirname,&$dirnum, &$filenum){
  5. $dir=opendir($dirname);
  6. echo readdir($dir)."
    "; //Read files in the current directory
  7. echo readdir($dir)."
    "; //Read the upper-level directory file
  8. while($filename=readdir($dir)){
  9. //What needs to be determined is whether the path under $dirname is a directory
  10. $newfile=$dirname."/".$filename ;
  11. //The is_dir() function determines whether the path of the current script is a directory
  12. if(is_dir($newfile)){
  13. //Traverse the directories or files in its subdirectories through the recursive function
  14. total($newfile, $dirnum,$filenum);
  15. $dirnum++;
  16. }else{
  17. $filenum++;
  18. }
  19. }
  20. closedir($dir);
  21. }
  23. $dirnum=0;
  24. $filenum=0;
  25. total("E :/AppServ/www/phpMyAdmin",$dirnum,$filenum);
  26. echo "Total number of directories: ".$dirnum."
    ";
  27. echo "Total number of files: ".$filenum."
