foreach不填充數組

我試圖遞歸地掃描文件夾結構並填充數組與路徑到每個找到的文件。但是print_r($fileArray)給我一個空數組作爲輸出？像這樣：Array ()foreach不填充數組

錯誤在哪裏？

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

的var_dump（$項目）的輸出;您的foreach內：

在你的foreach中進行一些調試。 – Jessica

var_dump（$ item）;'foreach'內部的輸出是什麼？ – vitozev

如果您總是點擊'continue'語句，'$ fileArray'將爲空。正如@Jessica指出的那樣，一些調試會有所幫助。另外，如果你既不使用它，也不將它返回給調用者，那麼'$ structureArray'有什麼意義？ – YvesLeBorg

我用這個代碼來生成目錄中的PHP文件列表，並從每個文件名

刪除擴展名爲「.PHP」，而無需使用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; 
    }

的

PS所有文件名將在一個數組中，甚至子目錄中的文件

這就是我想要的。謝謝！ –

不客氣:) –

我不知道你是否已經試過這個，但glob($file_path."*");應該返回給定文件夾中的所有文件。它內置於php並且相當短。

是的，但不幸的是不遞歸。 –
