PHP 获取文件列表，包括子目录

PHP get file listing including sub directories

提问by Washburn

I am trying to retrieve all images in a directory, including all subdirectories. I am currently using

我正在尝试检索目录中的所有图像，包括所有子目录。我目前正在使用

$images = glob("{images/portfolio/*.jpg,images/portfolio/*/*.jpg,images/portfolio/*/*/*.jpg,images/portfolio/*/*/*/*.jpg}",GLOB_BRACE);

This works, however the results are:

这有效，但结果是：

images/portfolio/1.jpg
images/portfolio/2.jpg
images/portfolio/subdirectory1/1.jpg
images/portfolio/subdirectory1/2.jpg
images/portfolio/subdirectory2/1.jpg
images/portfolio/subdirectory2/2.jpg
images/portfolio/subdirectory1/subdirectory1/1.jpg
images/portfolio/subdirectory1/subdirectory1/2.jpg

I want it to do a whole directory branch at a time so the results are:

我希望它一次执行整个目录分支，因此结果是：

images/portfolio/1.jpg
images/portfolio/2.jpg
images/portfolio/subdirectory1/1.jpg
images/portfolio/subdirectory1/2.jpg
images/portfolio/subdirectory1/subdirectory1/1.jpg
images/portfolio/subdirectory1/subdirectory1/2.jpg
images/portfolio/subdirectory2/1.jpg
images/portfolio/subdirectory2/2.jpg

Greatly appreciate any help, cheers!

非常感谢任何帮助，干杯！

P.S It would also be great if I could just get all subdirectories under portfolio without having to specifically state each directory with a wild card.

PS 如果我可以只获取投资组合下的所有子目录而不必用通配符专门说明每个目录，那也很棒。

from glob example

来自glob 示例

if ( ! function_exists('glob_recursive'))
{
    // Does not support flag GLOB_BRACE        
   function glob_recursive($pattern, $flags = 0)
   {
     $files = glob($pattern, $flags);
     foreach (glob(dirname($pattern).'/*', GLOB_ONLYDIR|GLOB_NOSORT) as $dir)
     {
       $files = array_merge($files, glob_recursive($dir.'/'.basename($pattern), $flags));
     }
     return $files;
   }
}

Solution:

解决方案：

<?php
$path = realpath('yourfolder/examplefolder');
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
{
        echo "$filename</br>";
}
?>

Here's a simpler approach:

这是一个更简单的方法：

Instead of using:

而不是使用：

$path = realpath('yourfolder/examplefolder/*');
glob($path);

You'll have to use:

你必须使用：

$path = realpath('yourfolder/examplefolder').'/{**/*,*}';
glob($path, GLOB_BRACE);

This last one will use bracing, and it is, in fact, a shorthand for this code:

最后一个将使用支撑，实际上，它是此代码的简写：

$path = realpath('yourfolder/examplefolder');

$self_files = glob($path . '/*');
$recursive_files = glob($path . '/**/*');

$all_files = $self_files + $recursive_files; // That's the result you want

You may also want to filter directories from your result. glob()function has GLOB_ONLYDIRflag. Let's use it to diff out our result.

您可能还想从结果中过滤目录。glob()函数有GLOB_ONLYDIR标志。让我们用它来区分我们的结果。

$path =  realpath('yourfolder/examplefolder/') . '{**/*,*}';

$all_files = array_diff(
  glob($path, GLOB_BRACE),
  glob($path, GLOB_BRACE | GLOB_ONLYDIR)
);

This function supports GLOB_BRACE:

此函数支持 GLOB_BRACE：

function rglob($pattern_in, $flags = 0) {
    $patterns = array ();
    if ($flags & GLOB_BRACE) {
        $matches;
        if (preg_match_all ( '#\{[^.\}]*\}#i', $pattern_in, $matches )) {
            // Get all GLOB_BRACE entries.
            $brace_entries = array ();
            foreach ( $matches [0] as $index => $match ) {
                $brace_entries [$index] = explode ( ',', substr ( $match, 1, - 1 ) );
            }

            // Create cartesian product.
            // @source: https://stackoverflow.com/questions/6311779/finding-cartesian-product-with-php-associative-arrays
            $cart = array (
                    array () 
            );
            foreach ( $brace_entries as $key => $values ) {
                $append = array ();
                foreach ( $cart as $product ) {
                    foreach ( $values as $item ) {
                        $product [$key] = $item;
                        $append [] = $product;
                    }
                }
                $cart = $append;
            }

            // Create multiple glob patterns based on the cartesian product.
            foreach ( $cart as $vals ) {
                $c_pattern = $pattern_in;
                foreach ( $vals as $index => $val ) {
                    $c_pattern = preg_replace ( '/' . $matches [0] [$index] . '/', $val, $c_pattern, 1 );
                }
                $patterns [] = $c_pattern;
            }
        } else
            $patterns [] = $pattern_in;
    } else
        $patterns [] = $pattern_in;

    // @source: http://php.net/manual/en/function.glob.php#106595
    $result = array ();
    foreach ( $patterns as $pattern ) {
        $files = glob ( $pattern, $flags );
        foreach ( glob ( dirname ( $pattern ) . '/*', GLOB_ONLYDIR | GLOB_NOSORT ) as $dir ) {
            $files = array_merge ( $files, rglob ( $dir . '/' . basename ( $pattern ), $flags ) );
        }
        $result = array_merge ( $result, $files );
    }
    return $result;
}

Simple class:

简单类：

<?php
    class AllFiles {
        public $files = [];
        function __construct($folder) {
            $this->read($folder);           
        }
        function read($folder) {
            $folders = glob("$folder/*", GLOB_ONLYDIR);
            foreach ($folders as $folder) {
                $this->files[] = $folder . "/";
                $this->read( $folder );
            }
            $files = array_filter(glob("$folder/*"), 'is_file');
            foreach ($files as $file) {
                $this->files[] = $file;

        function __toString() {

    };

    $allfiles = new AllFiles("baseq3");
    echo $allfiles;

Example output:

示例输出：

baseq3/gfx/
baseq3/gfx/2d/
baseq3/gfx/2d/numbers/
baseq3/gfx/2d/numbers/eight_32b.tga
baseq3/gfx/2d/numbers/five_32b.tga
baseq3/gfx/2d/numbers/four_32b.tga
baseq3/gfx/2d/numbers/minus_32b.tga
baseq3/gfx/2d/numbers/nine_32b.tga

If you don't want the folders in the list, just comment this line out:

如果您不想要列表中的文件夹，只需注释掉这一行：

$this->files[] = $folder . "/";
