How to use PHP to recursively traverse files in a specified directory and count the number of files

This article mainly introduces how to use PHP to recursively traverse files in a specified directory and count the number of files, involving PHP File and directory operation skills are of great practical value. Friends who need them can refer to them

The example in this article describes how PHP recursively traverses files in a specified directory and counts the number of files. Share it with everyone for your reference. The specific implementation method is as follows:

//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)."
"; //读取当前目录文件

echo readdir($dir)."
"; //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."
";

echo "文件总数:".$filenum."
";

//遍历指定文件目录与文件数量结束
