Question

为了循环目录中的所有文件，我在php中创建了这段代码：

$dir = new DirectoryIterator(dirname(__FILE__));
$files = scandir($dir.'/');
foreach($files as $file) 
{
    echo $file;
    echo "\n";
}

但是我无法列出目录的多个子目录中的所有文件。

Answer 1

使用RecursiveDirectoryIterator

<?php

$path = realpath('/etc');

$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach($objects as $name => $object){
    echo "$name\n";
}

?>

Answer 2

试试这个。 See this in php manual

function loop_dir($dir) {
    $iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir),
                                              RecursiveIteratorIterator::CHILD_FIRST);
    foreach ($iterator as $path) {
      echo $path
    }
}

Answer 3

这很简单：

$dir = dir('DIRECTORY_TO_DISPLAY_HERE');
while (($file = $dir->read()) !== false) {
    if ($file != '..' && $file != '.') {
        echo $file;
    }
}
$dir->close();

列出目录目录中的文件
