本文实例讲述了PHP递归遍历指定目录的文件并统计文件数量的方法。分享给大家供大家参考。具体实现方法如下:

<&#63;php
//递归函数实现遍历指定文件下的目录与文件数量
function total($dirname,&$dirnum,&$filenum){
  $dir=opendir($dirname);
  echo readdir($dir)."<br>"; //读取当前目录文件
  echo readdir($dir)."<br>"; //读取上级目录文件
  while($filename=readdir($dir)){
    //要判断的是$dirname下的路径是否是目录
    $newfile=$dirname."/".$filename;
    //is_dir()函数判断的是当前脚本的路径是不是目录
    if(is_dir($newfile)){
      //通过递归函数再遍历其子目录下的目录或文件
      total($newfile,$dirnum,$filenum);
      $dirnum++;
    }else{
      $filenum++;
    }
  }
  closedir($dir);
}
$dirnum=0;
$filenum=0;
total("E:/AppServ/www/phpMyAdmin",$dirnum,$filenum);
echo "目录总数:".$dirnum."<br>";
echo "文件总数:".$filenum."<br>";
//遍历指定文件目录与文件数量结束
