如何编写php脚本来更新文件列表？ [关闭]

Question

i have a program to update some file from my site and i do all work but i have a problem in update.php script

my application side update cod is(in C#):

    public string[] NeededFiles = { "teknomw3.dll" };
    public string HomePageUrl = "http://se7enclan.ir";
    public string NewsUrl = "http://se7enclan.ir/news";
    public string DownloadUrl = "http://se7enclan.ir/";
    public string UpdateList = "http://se7enclan.ir/update.php?action=list";
    public string UpdateBaseUrl = "http://se7enclan.ir/Update/";

and my update directory on my site as you see(all files is here.):

http://se7enclan.ir/Update/

so what script must be in update.php that i can use this: "update.php?action=list"

this update.php script must work like this site: http://mw3luncher.netai.net/update.php?action=list

I understand your problem man. Here is a solution:

<?PHP
  function getFileList($dir)
  {
    // array to hold return value
    $retval = array();

    // add trailing slash if missing
    if(substr($dir, -1) != "/") $dir .= "/";

    // open pointer to directory and read list of files
    $d = @dir($dir) or die("getFileList: Failed opening directory $dir for reading");
    while(false !== ($entry = $d->read())) {
      // skip hidden files
      if($entry[0] == ".") continue;
      if(is_dir("$dir$entry")) {
        $retval[] = array(
          "name" => "$dir$entry/",
          "type" => filetype("$dir$entry"),
          "size" => 0,
          "lastmod" => filemtime("$dir$entry")
        );
      } elseif(is_readable("$dir$entry")) {
       $retval[] = array(
          "name" => "$dir$entry",
          "type" => mime_content_type("$dir$entry"),
          "size" => filesize("$dir$entry"),
          "lastmod" => filemtime("$dir$entry")
        );
      }
   }
    $d->close();

    return $retval;
  }
?>

You can use this function as follows:

<?PHP
  // examples for scanning the current directory
  $dirlist = getFileList(".");
  $dirlist = getFileList("./");
?>

And to output the results to an HTML page we just loop through the returned array:

<?PHP
  // output file list as HTML table
  echo "<table border="1">
";
  echo "<tr><th>Name</th><th>Type</th><th>Size</th><th>Last Mod.</th></tr>
";
  foreach($dirlist as $file) {
    echo "<tr>
";
    echo "<td>{$file['name']}</td>
";
    echo "<td>{$file['type']}</td>
";
    echo "<td>{$file['size']}</td>
";
    echo "<td>",date('r', $file['lastmod']),"</td>
";
    echo "</tr>
";
  }
  echo "</table>

";
?>

Hope it helps!
