文件到阵列 - 水珠VS RecursiveIteratorIterator

我做添加文件的列表，以数组：文件到阵列 - 水珠VS RecursiveIteratorIterator

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

我可输出print_r(array_values($array));的阵列。

现在我试图做同样的RecursiveIteratorIterator：

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

这并不工作就像预期的，当我尝试输出数组？

print_r(array_values($files));

我怎样才能得到相同的结果？

'$ files'是一个迭代，而不是阵列。 – Barmar

你需要用'foreach'迭代它。 – Barmar

@Barmar请你详细说明一下吗？我很新的编码。 – MikeSkril

迭代器与阵列不一样。要使用迭代器，必须用foreach来迭代它。

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

输出：

Array 
(
    [0] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/. 
      [fileName:SplFileInfo:private] => . 
     ) 

    [1] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/.. 
      [fileName:SplFileInfo:private] => .. 
     ) 

    [2] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/sub1/. 
      [fileName:SplFileInfo:private] => . 
     ) 

    [3] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/sub1/.. 
      [fileName:SplFileInfo:private] => .. 
     ) 

    [4] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/sub1/filea.jpg 
      [fileName:SplFileInfo:private] => filea.jpg 
     ) 

    [5] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/sub1/fileb.jpg 
      [fileName:SplFileInfo:private] => fileb.jpg 
     ) 

    [6] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/sub2/. 
      [fileName:SplFileInfo:private] => . 
     ) 

    [7] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/sub2/.. 
      [fileName:SplFileInfo:private] => .. 
     ) 

    [8] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/sub2/sub21/. 
      [fileName:SplFileInfo:private] => . 
     ) 

    [9] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/sub2/sub21/.. 
      [fileName:SplFileInfo:private] => .. 
     ) 

    [10] => SplFileInfo Object 
     (
      [pathName:SplFileInfo:private] => test.dir/sub2/sub21/filee.jpg 
      [fileName:SplFileInfo:private] => filee.jpg 
     ) 

)

我已经试过了，但是当我做'print_r（array_values（$ file_array））;'时，数组是空的。 – MikeSkril

我只是试过了，它适用于我。也许你在创建迭代器时没有给出正确的'$ path'。 – Barmar

我想我现在明白了。谢谢您的帮助！ – MikeSkril
