PHP递归遍历指定目录的文件并统计文件数量的方法,
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:
<?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 ?>
希望本文所述对大家的php程序设计有所帮助。
