我想扫描目录和子目录,制作xml文件列表,从xml文件中获取内容并显示它.此功能无需OOP即可正常工作.我尝试创建一个类.我从函数main调用函数scandir_through.我没有错误,结果也是如此.

class data {

var $dir = 'D:\wamp4\www\begin';

public function scandir_through($dir)

{

$items = glob($dir . '/*');

for ($i = 0; $i < count($items); $i++) {

if (is_dir($items[$i])) {

$add = glob($items[$i] . '/*');

$items = array_merge($items, $add);

}

}

return $items;

}

public function main()

{

$scan_tree = $this->scandir_through($dir);

echo "

• "."";

foreach ($scan_tree as $key=>$file){

$url = $file;

$xml = simplexml_load_file($url);

$book_count = count($xml->book);

for($i = 0; $i < $book_count; $i++) {

$book = $xml->book[$i];

$title=$xml->book[$i]->title;

$author=$xml->book[$i]->author;

//echo '';

//echo $file. " &nbsp ";

//echo $title. " &nbsp ";

//echo $author;

echo "

}

}

echo "

}

}

$d = new data();

$d->main();

?>
