foreach 不填充数组

Question

我正在尝试递归扫描文件夹结构，并用找到的每个文件的路径填充一个数组。但是 print_r($fileArray) 给我一个空数组作为输出？像这样：Array ( )

哪里错了？

function getFilePaths($path){
    $structureArray = [];
    $fileArray = [];

    foreach(new DirectoryIterator($path) as $item){

        if($item->isDir()){
            if(!$item->isDot()) { 
                $structureArray[$item->getFilename()] = getFilePaths($item->getPathname());
            }
            continue;
        }

        $fileArray[] = '"'. $item->getPathname() .'"';
    } 

    return $fileArray;
}

更新

var_dump( $item ) 的输出；在你的 foreach 里面：

object(DirectoryIterator)#9 (4) { ["pathName":"SplFileInfo":private]=> string(68) "music\sorted Doors Down\Seventeen Days Right Where I Belong.mp3" ["fileName":"SplFileInfo":private]=> string(27) "01 Right Where I Belong.mp3" ["glob":"DirectoryIterator":private]=> bool(false) ["subPathName":"RecursiveDirectoryIterator":private]=> string(0) "" } object(DirectoryIterator)#9 (4) { ["pathName":"SplFileInfo":private]=> string(59) "music\sorted Doors Down\Seventeen Days It's Not Me.mp3" ["fileName":"SplFileInfo":private]=> string(18) "02 It's Not Me.mp3" ["glob":"DirectoryIterator":private]=> bool(false) ["subPathName":"RecursiveDirectoryIterator":private]=> string(0) "" } object(DirectoryIterator)#9 (4) { ["pathName":"SplFileInfo":private]=> string(58) "music\sorted Doors Down\Seventeen Days\AlbumArtSmall.jpg" ["fileName":"SplFileInfo":private]=> string(17) "AlbumArtSmall.jpg" ["glob":"DirectoryIterator":private]=> bool(false) ["subPathName":"RecursiveDirectoryIterator":private]=> string(0) "" } object(DirectoryIterator)#9 (4) { ["pathName":"SplFileInfo":private]=> string(51) "music\sorted Doors Down\Seventeen Days\Folder.jpg" ["fileName":"SplFileInfo":private]=> string(10) "Folder.jpg" ["glob":"DirectoryIterator":private]=> bool(false) ["subPathName":"RecursiveDirectoryIterator":private]=> string(0) "" } object(DirectoryIterator)#9 (4) { ["pathName":"SplFileInfo":private]=> string(59) "music\sorted Doors Down\The Better Life Kryptonite.mp3" ["fileName":"SplFileInfo":private]=> string(17) "01 Kryptonite.mp3" ["glob":"DirectoryIterator":private]=> bool(false) ["subPathName":"RecursiveDirectoryIterator":private]=> string(0) "" } object(DirectoryIterator)#9 (4) { ["pathName":"SplFileInfo":private]=> string(54) "music\sorted Doors Down\The Better Life Loser.mp3" ["fileName":"SplFileInfo":private]=> string(12) "02 Loser.mp3" ["glob":"DirectoryIterator":private]=> bool(false) ["subPathName":"RecursiveDirectoryIterator":private]=> string(0) "" } object(DirectoryIterator)#9 (4) { ["pathName":"SplFileInfo":private]=> string(59) "music\sorted Doors Down\The Better Life\AlbumArtSmall.jpg" ["fileName":"SplFileInfo":private]=> string(17) "AlbumArtSmall.jpg" ["glob":"DirectoryIterator":private]=> bool(false) ["subPathName":"RecursiveDirectoryIterator":private]=> string(0) "" } object(DirectoryIterator)#9 (4) { ["pathName":"SplFileInfo":private]=> string(52) "music\sorted Doors Down\The Better Life\Folder.jpg" ["fileName":"SplFileInfo":private]=> string(10) "Folder.jpg" ["glob":"DirectoryIterator":private]=> bool(false) ["subPathName":"RecursiveDirectoryIterator":private]=> string(0) "" } object(DirectoryIterator)#5 (4) { ["pathName":"SplFileInfo":private]=> string(55) "music\unsorted Club Rocker (Mike Candys Radio Ed.mp3" ["fileName":"SplFileInfo":private]=> string(40) "01 Club Rocker (Mike Candys Radio Ed.mp3" ["glob":"DirectoryIterator":private]=> bool(false) ["subPathName":"RecursiveDirectoryIterator":private]=> string(0) "" } object(DirectoryIterator)#7 (4) { ["pathName":"SplFileInfo":private]=> string(69) "music\unsorted\tagged7ers - Bis dahin bin ich tot ft.

Answer 1

我使用此代码在目录中生成 php 个文件的列表，并从每个文件名中删除扩展名“.php”

不使用 DirectoryIterator

function getFiles($directory){
        $files = array_diff(scandir($directory), array('.','..','.htaccess'));
        foreach($files as $f){
            if(strstr($f, ".php"))
                $fileArray[] = str_replace(".php","",$f);
            else {
                $fileArray[$f] = getFiles($directory."/".$f);
            }
        }
        return $fileArray;
    }

P.S。所有文件名都在一个数组中，即使是子目录中的文件

Answer 2

我不知道您是否已经尝试过，但是 glob($file_path."*"); 应该 return 给定文件夹中的所有文件。它内置于 php 中并且相当短。

foreach 不填充数组

foreach does not fill array

php
