php目录操作实例代码

代码如下:
<?php
    /**
    * listdir
    */
    header("content-type:text/html;charset=utf-8");

    $dirname = "./final/factapplication";

    function listdir($dirname) {
        $ds = opendir($dirname);
        while (false !== ($file = readdir($ds))) {
            $path = $dirname.'/'.$file;
            if ($file != '.' && $file != '..') {
                if (is_dir($path)) {
                    listdir($path);
                } else {
                    echo $file."<br>";
                }
            }
        }
        closedir($ds);
    }
    listdir($dirname);

核心：递归的经典应用，以及文件和目录的基本操作。

代码如下:
<?php
    /**
    * copydir
    */

    $srcdir = "../fileupload";
    $dstdir = "b";

    function copydir($srcdir, $dstdir) {
        mkdir($dstdir);
        $ds = opendir($srcdir);

        while (false !== ($file = readdir($ds))) {
            $path = $srcdir."/".$file;
            $dstpath = $dstdir."/".$file;
            if ($file != "." && $file != "..") {
                if (is_dir($path)) {
                    copydir($path, $dstpath);
                } else {
                    copy($path, $dstpath);
                }
            }
        }
