README

A Virtual File System (VFS) directory iterator for PHP, compatible with the API of RecursiveDirectoryIterator and DirectoryIterator, able to mimic original class behaviour, while creating a virtual, non-existent file system from a PHP array.

输入

工厂接受两个参数

• 字符串或数组：可以是JSON文件的路径，也可以是数组本身。
• (可选)要迭代的初始路径，例如："/music/oldies"

数组格式

每个键代表一个目录，每个值是文件名本身。

结构示例

 '/music' => [
        '1993 Haddaway - What Is Love (Remixes)' => [
            "1 - Haddaway - What Is Love (7'' Mix).wav",
            "2 - Haddaway - What Is Love (Eat This Mix).wav",
            "3 - Haddaway - What Is Love (Tour De Trance Mix).wav"
        ],
        "1985 Paul Hardcastle - 19 (The Final Story) [601 814]" => [
            "01 - Paul Hardcastle - 19 (The Final Story).wav",
            "02 - Paul Hardcastle - 19 (Destruction Mix).wav"
        ]
    ]

JSON格式

相同。请参阅 vfs-example.json 以获取示例。

输出

以下方法受到支持并完全模拟

public function getFilename();

public function getPath();

public function isDir();

public function isDot();

public function isFile();

public function current();

public function next();

public function valid();

public function getChildren();

public function hasChildren();

public function rewind();

请参阅 这里 了解原始API说明。

示例工作代码

    $path = ... // define starting path
    $vfsArray = []; // paste the VFS array here. See above.
    $iterator = FileSystemFactory::create('vfs', [$path, $vfsArray]);
    $iterator->rewind();
    echo 'Browsing path ' . $iterator->getPath() . "...\n";

    while ($iterator->valid()) {
        $file = $iterator->current();

        if ($file->isDot() || $file->isFile()) {
            continue;
        }

        echo 'Processing directory ' . $file->getFilename() . "\n";
        // process (string)$file.....
        $results[] = $result;

        $iterator->next();
    }

警告

不建议在 foreach 循环中使用。
