foreach不填充数组

懒汉

我试图递归扫描文件夹结构，并用指向每个找到的文件的路径填充数组。但是print_r($fileArray)给我一个空数组作为输出？像这样：Array ( )

错误在哪里？

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\3 Doors Down\Seventeen Days\01 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\3 Doors Down\Seventeen Days\02 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\3 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\3 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\3 Doors Down\The Better Life\01 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\3 Doors Down\The Better Life\02 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\3 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\3 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\01 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\tagged\257ers - Bis dahin bin ich tot ft.

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

无需使用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;
    }

PS所有文件名将位于单个数组中，即使文件位于子目录中
