Question

使用以下脚本，我尝试打印这些目录下的所有目录和文件的列表。但它没有这样做。

# Snippet that lists all the directories and files under that directory

$dir_list = scandir("/");
for($var=0;$var<count($dir_list);$var++) {
    if(is_dir($dir_list[$var])) {
        $dh = opendir($dir_list[$var]);
        echo "Name of directory : ".$dir_list[$var];
        echo "<br />";
        while(false !== ($filename = readdir($dh))) {
            echo $filename;
            echo "<br />";
        }
    }
    echo $dir_list[$var];echo "<br />";
}
#end

相反，这是我作为输出得到的。这是所有目录的列表。当有这么多目录时，if语句只执行一次。那是为什么？

Answer 1

“/”代表基于unix的系统。你好像是Windows（“E：\”）。

尝试将scandir("/")更改为scandir('E:\')

Answer 2

应该是，

$dir_list = scandir("/");

for($var=0;$var<count($dir_list);$var++) {
    if(is_dir($dir_list[$var]))
    {
        $dh = opendir($dir_list[$var]);
        echo "<b>Name of directory : ".$dir_list[$var].'</b><br>';
        if($dh!=false && $dh!= '.' && $dh!='..')
        {
          while(false != ($filename = readdir($dh))) {
              echo $filename;
          }
        }
    }
    else
    {
        echo "Name of file : ".$dir_list[$var].'<br>';
    }
}

如果您使用的是Windows而不是scandir()方法，则应该传递目录的绝对路径。

Answer 3

由于你的问题完全不同，我做了另一个答案：

1°你需要递归 2°而不是使用复杂的功能（opendir，readdir）scandir就足够了

根据您的代码：

<?php

function displayRecursive($path){ 
    $dir_sep = DIRECTORY_SEPARATOR;
    $path = rtrim($path, '/').'/'; //
$dir_list = scandir($path);
    echo '<ul>';
foreach($dir_list as $file){
        if ($file[0] == '.')
            continue;

        echo '<li>';
        if(is_dir($path.$dir_sep.$file)){
            echo "Name of directory : ".$dir_list[$var];
            displayRecursive($path.$dir_sep.$file);
        }
        else{
            echo $filename;
        }
        echo '</li>';
}
    echo '</ul>';

}
$first_dir = '/';
displayRecursive($first_dir)

为什么我没有得到文件和目录的名称？
