Question

我试图列出目录并生成一棵树。我有这个功能，但问题是他给了我第一个空数组。当进入easytreegrid时给我一个空格子

    function listar_carpeta_archivo($dir = "C:/xampp/htdocs/Archivos") {

    $arr = array();
    foreach (new DirectoryIterator($dir) as $fileInfo) {

        if (!$fileInfo->isDot()) {
            $arr[]= $fileInfo->getBasename();
            if ($fileInfo->isDir()) {

               $arr[] = listar_carpeta_archivo($fileInfo->getPathname());

            }

        }

}

    return $arr;
}

给我这个输出：

[0] => Array
    (
    )

[1] => Array
    (
        [0] => 5962R1121310VXC
        [1] => Array
            (
                [0] => fdgtdfg
                [1] => Array
                    (
                        [0] => Ingreso
                        [1] => Array
                            (
                                [0] => 2015-08-10 15-13-17
                                [1] => Array
                                    (
                                        [0] => Nuevo documento de texto - copia (2).txt
                                        [1] => Nuevo documento de texto - copia (3).txt
                                        [2] => Nuevo documento de texto - copia.txt
                                        [3] => Nuevo documento de texto.txt
                                    )

                            )

                    )

            )

我想要这个输出：

功能示例。试试这个。希望这能帮助你。

function tree(DirectoryIterator $dir) {
    $data = array(
        'name' => $dir->getPathname(),
        'size' => $dir->getSize(),
        // etc...
    );

    foreach ($dir as $node) {
        if ($node->isDir() && !$node->isDot()) {
            // call recursion
            $data['children'][] = tree(new DirectoryIterator($node->getPathname()));
        } else if ($node->isFile()) {
            $data['children'][] = array(
                'name' => $node->getFilename(),
                'size' => $node->getSize(),
                // etc...
            );
        }
    }

    return $data;
}

使用方法：

$tree = tree(new DirectoryIterator('C:/xampp/htdocs/Archivos'));
echo '<pre>';
print_r($tree);
echo '</pre>';
die();
