推荐答案

有很多方法.较旧的方法是 scandir ，但

There's a lot of ways. The older way is scandir but DirectoryIterator is probably the best way.

还有 readdir (与以下是一些示例，说明如何使用每个示例打印当前目录中的所有文件:

Here are some examples on how to use each one to print all the files in the current directory:

foreach (new DirectoryIterator('.') as $file) {
    if($file->isDot()) continue;
    print $file->getFilename() . '<br>';
}

scandir用法:

scandir usage:

$files = scandir('.');
foreach($files as $file) {
    if($file == '.' || $file == '..') continue;
    print $file . '<br>';
}

opendir和readdir用法:

opendir and readdir usage:

if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
        if($file == '.' || $file == '..') continue;
        print $file . '<br>';
    }
    closedir($handle);
}

glob用法:

glob usage:

foreach (glob("*") as $file) {
    if($file == '.' || $file == '..') continue;
    print $file . '<br>';
}

如评论中所述，glob很不错，因为我在那里使用的星号实际上可以用于对文件进行匹配，因此glob('*.txt')会为您提供文件夹中的所有文本文件，而glob('image_*')会为您提供获取所有以image _

As mentioned in the comments, glob is nice because the asterisk I used there can actually be used to do matches on the files, so glob('*.txt') would get you all the text files in the folder and glob('image_*') would get you all files that start with image_
