PHP-scandir()並取得目錄下檔案

scandir 回傳值是Array，回傳值的第一項是「.」，就是目前資料夾的意思，第二項是「..」也就是上一個資料夾，但是沒辦法像glob那樣指定到檔案格式

$arr_Scan = scandir('./');

用scandir()印出結果

Array
(
    [0] => .
    [1] => ..
    [2] => .DS_Store
    [3] => .git
    [4] => FileInc
    [5] => SPD.spd
    [6] => config
    [7] => getFileTicket.php
    [8] => index.php
    [9] => readme.mk
)

列出目錄下檔案

function dirToArray($dir)
{

    $result = array();

    $cdir = scandir($dir);
    foreach ($cdir as $key => $value) {
        if (!in_array($value, array(".", ".."))) {
            if (is_dir($dir . DIRECTORY_SEPARATOR . $value)) {
                $result[$value] = dirToArray($dir . DIRECTORY_SEPARATOR . $value);
            } else {
                $value = iconv("BIG5", "UTF-8", $value);
                $result[] = $value;
            }
        }
    }

    return $result;
}

可以完整找出資料夾下的所有目錄與檔案．
