Question

我有这个PHP代码列出目录中的所有文件并输出文件大小和下载链接。

<?
function human_filesize($bytes, $decimals = 2) {
$size = array(' B',' kB',' MB',' GB',' TB',' PB',' EB',' ZB',' YB');
$factor = floor((strlen($bytes) - 1) / 3);
return sprintf("%.{$decimals}f", $bytes / pow(1024, $factor)) . @$size[$factor];
}

$excludedFiles = array('.','..');

$excludedExtensions = array ('html','htm','php');

// Convert to lower case so we are not case-sensitive
for ($i = 0; isset($excludedFiles[$i]); $i++) $excludedFiles[$i] = strtolower(ltrim($excludedFiles[$i],'.'));
for ($i = 0; isset($excludedExtensions[$i]); $i++) $excludedExtensions[$i] = strtolower($excludedExtensions[$i]);


// Define the full path to your folder from root
$dir = "./";

// Open the folder
$dir_handle = @opendir($dir) or die("Unable to open $dir");

// Loop through the files
while ($file = readdir($dir_handle)) {

$extn = explode('.',$file);
$extn = array_pop($extn);

if (!in_array(strtolower($file),$excludedFiles) && !in_array(strtolower($extn),$excludedExtensions)){

if($file == "." || $file == ".." )


continue;

echo "<tr>
      <td>
     <a class='Testo' href=\"$file\" download>$file</a></td>
     <td><font class='TestoPiccoloBo'>[" . human_filesize(filesize($file)) . "]</font></td>
    </tr>";
 }
 }

// Close
closedir($dir_handle);



?>

我希望列表按字母顺序排列，所以我添加了

$files = scandir($dir);

在$dir行和

之后

foreach ($files as $file){

在while ($file = readdir($dir_handle)) {行之后

和

在closedir($dir_handle);行之前

现在文件列表按字母顺序排列，但列表却是无穷无尽的。列表一遍又一遍地开始，就像一个循环。我究竟做错了什么？这是完成此任务的正确方法吗？任何帮助将非常感激。谢谢！

您可以将文件夹放在一个数组中，并使用php sort函数对其进行排序。然后打印出来：

<?
function human_filesize($bytes, $decimals = 2) {
$size = array(' B',' kB',' MB',' GB',' TB',' PB',' EB',' ZB',' YB');
$factor = floor((strlen($bytes) - 1) / 3);
return sprintf("%.{$decimals}f", $bytes / pow(1024, $factor)) . @$size[$factor];
}

$excludedFiles = array('.','..');
$arrayFiles = array();
$excludedExtensions = array ('html','htm','php');

// Convert to lower case so we are not case-sensitive
for ($i = 0; isset($excludedFiles[$i]); $i++) $excludedFiles[$i] = strtolower(ltrim($excludedFiles[$i],'.'));
for ($i = 0; isset($excludedExtensions[$i]); $i++) $excludedExtensions[$i] = strtolower($excludedExtensions[$i]);


// Define the full path to your folder from root
$dir = "./";

// Open the folder
$dir_handle = @opendir($dir) or die("Unable to open $dir");

// Loop through the files
while ($file = readdir($dir_handle)) {

$extn = explode('.',$file);
$extn = array_pop($extn);

if (!in_array(strtolower($file),$excludedFiles) && !in_array(strtolower($extn),$excludedExtensions)){

if($file == "." || $file == ".." )
continue;

$arrayFiles[] =  $file;

 }
 } // dunno what are these } so i put my loop after

// Close
closedir($dir_handle);

sort($arrayFiles);

foreach ($arrayFiles as $file) {
    echo "<tr>
      <td>
     <a class='Testo' href=\"$file\" download>$file</a></td>
     <td><font class='TestoPiccoloBo'>[" . human_filesize(filesize($file)) . "]</font></td>
    </tr>";
}
?>
