PHP获取所有子目录和所有文件的列表 - php get list of all subdirectories and all files

php get list of all subdirectories and all files

本文关键字：列表文件子目录获取 PHP | 更新日期: 2023-09-27

在php中获取所有子目录列表和另一个给定目录下的所有文件列表的最佳方法是什么?我可以使用非纯php代码，只要我可以使用它从php(例如。一个c/java/python/…程序)。一些比纯recursion更快的东西，一些内置在某些语言中的东西(因为这些东西往往很快)

查看RecursiveDirectoryIterator:

foreach (new RecursiveDirectoryIterator('yourDir') as $file) {
    // you don't want the . and .. dirs, do you?
    if ($file->isDot()) {
        continue;
    }
    if ($file->isDir()) {
        // dir
    } else {
        // file
    }
}

如果您不喜欢查找内容，您可以在查找结果中运行opendir()循环。

if (exec('find /startdir -type d -print', $outputarray)) {
  foreach ($outputarray as $onepath) {
    // do stuff in $onepath
  }
}

你指定了"not pure PHP"作为选项，对吗?: -)

摘自php.net的glob()文档:

$path[] = 'starting_place/*';
while(count($path) != 0) {
  $v = array_shift($path);
  foreach(glob($v) as $item) {
    if(is_dir($item))
      $path[] = $item . '/*';
    else if (is_file($item)) {
      //do something
    }
  }
}

class Dir_helper{
    public function __construct(){
    }
    public function getWebdirAsArray($rootPath){
        $l1 = scandir($rootPath);
        foreach ($this->getFileList($rootPath) as $r1){
        if ($r1['type'] == 'dir'){
            if (preg_match("/'./", $r1['name'])){
            $toplevel[] =  $r1['name'];
            } else {
            if (preg_match("/'d/",$r1['name'])){
                $seclevel[] = $this->getFileList($r1['name']);
            }
            }
        }
        }
        foreach ($seclevel as $sl){
        foreach ($sl as $cur){
            $sub[] = $cur['name'];
        }
        }
        return $result = array_merge((array)$toplevel, (array)$sub);
    }
    public function getFileList($dir){
        $retval = array();
        if(substr($dir, -1) != "/") $dir .= "/";
        $d = @dir($dir) or die("getFileList: Failed opening directory $dir for reading");
        while(false !== ($entry = $d->read())) {
            if($entry[0] == ".") continue;
            if(is_dir("$dir$entry")) {
                $retval[] = array(
                "name" => "$dir$entry/",
                "type" => filetype("$dir$entry"),
                "size" => 0,
                "lastmod" => filemtime("$dir$entry")
                );
            } elseif(is_readable("$dir$entry")) {
                $retval[] = array(
                "name" => "$dir$entry",
                "type" => mime_content_type("$dir$entry"),
                "size" => filesize("$dir$entry"),
                "lastmod" => filemtime("$dir$entry")
                );
            }
        }
        $d->close();
        return $retval;
    }
}

使用php自带的RecursiveDirectoryIterator

编辑

类似:

$dirs  = array();
$files = array();
$dir = __DIR__ . '/foo';
$iterator = new RecursiveDirectoryIterator(new DirectoryIterator($dir));
foreach ($iterator as $dirElement) {
    if ($dirElement->isDir()) {
        $dirs[] $dirElement->getPathname();
    }
    if ($dirElement->isFile()) {
        $files[] = $dirElement->getPathname();
    }
}

由于您不想要递归，所以我只写了一些额外的位

// $dirs = [];
// Get All Files & Folders in $dir
$files = glob("$dir/*");
for ($i=0; $i < count($files); $i++) { 
    if (is_dir($files[$i])) {
        $files = array_merge($files, glob("$files[$i]/*"));
    //  $dirs[] = $files[$i]; // This can add the folder to a dir array
    }
}
// Remove folders from the list if you like
foreach ($files as $key => $file) {
    if (is_dir($file)) {
        unset($files[$key]);
    }
}
// Clean up the key numbers if you removed files or folders
$files = array_values($files);
