使用以下脚本，我尝试打印这些目录下所有目录和文件的列表。但事实并非如此。

# 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，这是我得到的输出。这是所有目录的列表。if当有这么多目录时，语句只执行一次。这是为什么 ？

应该是这样的，

$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，您应该传递目录的绝对路径。

“/”代表基于 Unix 的系统。你的似乎是 Windows ("E:\")。

尝试更改scandir("/")为scandir('E:\')

由于您的问题完全不同，我做了另一个答案：

1°你需要递归2°而不是使用复杂的函数（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)
