文件到陣列 - 水珠VS RecursiveIteratorIterator

Question

我做添加文件的列表，以數組：

$files = glob($path."*.*"); 

我可輸出print_r(array_values($array));的陣列。

現在我試圖做同樣的RecursiveIteratorIterator：

$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($path) 
); 

這並不工作就像預期的，當我嘗試輸出數組？

print_r(array_values($files)); 

我怎樣才能得到相同的結果？

Answer 1

迭代器與陣列不一樣。要使用迭代器，必須用foreach來迭代它。

<?php 
$path = "test.dir"; 
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($path) 
); 
$file_array = array(); 
foreach ($files as $f) { 
    $file_array[] = $f; 
} 
print_r($file_array); 

輸出：

Array

      [pathName:SplFileInfo:private] => test.dir/. 
      [fileName:SplFileInfo:private] => .
