如何從PHP上的本地文件夾/文件抓取數據並創建JSON數據

Question

我想輸出jason數據，在PHP上看起來像jasondata。 folder是文件夾的名稱，title位於info.txt的第一行。 info.txt位於文件夾下。每個info.txt中有三行，而這些行僅通過製作新行（而不是逗號）分開。文件夾books和我的php文件位於相同的文件夾下。我如何編寫一個PHP代碼？謝謝。 我的PHP代碼在這裏;

function books(){ 

    $array = []; 
    $story = glob("books/" . "*"); 

    foreach($story as $each){ 
     $title = file($each ."/info/txt", FILE_IGNORE_NEW_LINES); 
     $output = array (
      "title" => $title[0], 
      "folder" => $each #i would like to put the name of the folder here 
      ); 
     array_push($array,$review); 
    } 
    print(json_encode($array)); 
} 

Json數據應該看起來像;

{ 
    "books" : [ 
     { 
     "title": "Harry Potter and the Prisoner of Azkaban", 
     "folder": "harrypotter" 
     }, 
     { 
     "title": "The Hobbit", 
     "folder": "hobbit" 
     }, 
     ... (one entry like this for each folder inside books/) 
    ] 
} 

Answer 1

使用DirectoryIterator或SCANDIR功能，試試這個代碼波紋管

$dirs = '/directory/'; 
$dir = new DirectoryIterator($dirs); 
$array = array(); 
foreach ($dir as $key => $fileinfo) { 
    if ($fileinfo->isDir()) { 
     //remove hidden files or dot files 
     if ($fileinfo->getBasename() === '.' || $fileinfo->getBasename() === '..') continue); 

     //foldername 
     $array[$key]['folder'] = $fileinfo->getBasename(); 

     //title 
     $array[$key]['title'] = file($array[$key]['folder'].'/info.txt' , FILE_IGNORE_NEW_LINES); 
    } 
} 

$json = json_encode($array); 
print_r($json); 

讓我知道它的工作與否。

編輯 我嘗試在我的本地和它的工作

$dirs = 'books/'; 
$dir = new DirectoryIterator($dirs); 
$array = array(); 
foreach ($dir as $key => $fileinfo) { 
    if ($fileinfo->isDir()) { 
     //remove hidden files or dot files 
     if ($fileinfo->getBasename() === '.' || $fileinfo->getBasename() === '..') continue; 

     //foldername 
     $array[$key]['folder'] = $fileinfo->getBasename(); 

     //title 
     $array[$key]['title'] = file($dirs.'/'.$array[$key]['folder'].'/info.txt' , FILE_IGNORE_NEW_LINES); 
    } 
} 

$json = json_encode($array); 
echo '<pre>'.print_r($json, true).'</pre>';
