PHP recursively iterates through the files of the specified directory and counts the number of files,

This example describes how PHP recursively iterates through the files of a specified directory and counts the number of files. Share to everyone for your reference. The implementation method is as follows:

<?php//recursive function implementation traverse the directory and the number of files under the specified file function total ($dirname,& $dirnum,& $filenum) {  $dir =opendir ($dirname);  echo Readdir ($dir). "
"; Read the current catalog file  echo readdir ($dir). "
"; Read the parent directory file while  ($filename =readdir ($dir)) {    //To determine if the path under $dirname is a directory    $newfile = $dirname. " /". $filename;    The Is_dir () function determines whether the path of the current script is the directory    if (Is_dir ($newfile)) {      //through a recursive function and then iterates through the directory or file under its subdirectory      ($newfile, $dirnum, $ FileNum);      $dirnum + +;    } else{      $filenum + +;    }  }  Closedir ($dir);} $dirnum =0; $filenum =0;total ("E:/appserv/www/phpmyadmin", $dirnum, $filenum); echo "Total directory:" $dirnum. "
"; echo" Total Files: ". $filenum."
";//traverse the specified file directory and the number of files ends?>

I hope this article is helpful to everyone's PHP programming.
