php 遍历指定路径下所有目录与文件(示例)

/**
* php 遍历目录与文件
* by bbs.it-home.org
*/
function scan_all($dir){
    $temp = scandir($dir);
    if(is_array($temp) && count($temp)>2){
        array_shift($temp);
        array_shift($temp);
        foreach($temp as $v){
            $cur_dir=$dir.DIRECTORY_SEPARATOR.$v;
            if(is_dir($cur_dir)){
                echo $v." =>";
                echo "";                scan_all($cur_dir);
                echo "
";
            }else if(is_file($cur_dir)){
                echo "FILE:".$v."";
            }else{
                echo 'err';
            }
        }
    }
}
$dir = "D:/yourdir/";
scan_all($dir);

方法2，DirectoryIterator：

/**
* php 遍历目录与文件
* by bbs.it-home.org
*/
function directoryiterator($path)
{
    $iterator = new DirectoryIterator($path);
    foreach ($iterator as $fileinfo) {
        if(!$fileinfo->isDot())
        {
            if($fileinfo->isDir())
            {
                echo $fileinfo.'=>';                directoryiterator($path.DIRECTORY_SEPARATOR.$fileinfo);
                echo '
';
            }
            else
            {
                echo $fileinfo->getFilename().'';
            }
        }
    }
}
$dir = "D:/yourdir/";
directoryiterator($dir);
