php - 文件管理器 - 读取文件夹的内容

Question

我有一个问题，从文件夹(在本例中称为“上传”)读取文件:

这是脚本:

<div id="content">

        <?php
             echo "<h2> These is the list of the files: </h2>";

             $dir = dir("upload");

             while (($file = $dir->read()) !== false) {

                echo "<p>File name: " . $file . "</p>";
              }


              $dir->close();
          ?>
</div>

结果是这样的:

These is the list of the files:

File name: .

File name: ..

File name: prova.txt

File name: prova2.txt

File name: prova3.txt

File name: prova4.txt

它有效，因为正在从文件夹中读取内容。但是我怎样才能避免显示前两行呢？那两条线是什么？为什么显示它们？

Answer 1

试试这个:

while (($file = $dir->read()) !== false) 
{
    if($file != '.' && $file != '..')
    {
        echo "<p>File name: " . $file . "</p>";
    }
}
