如何將數組存儲到來自2個不同的php文件的json文件中

Question

我有2個不同的php文件用於從API中提取數據和用於存儲數據的一個JSON文件。我想，當我在服務器上運行的每個PHP文件，我的JSON文件將存儲陣列從兩個PHP文件。 E.g：

store.json

{ 
"articles": [{ 
      "author": "Rozina Sabur", 
      "title": "John Cleese to return to new BBC sitcom Edith - despite saying he would never be back", 
      "description": "Almost 40 years on from his starring role in Fawlty Towers, John Cleese is set to return to the BBC for a new sitcom.", 
      "url": "http:\/\/www.telegraph.co.uk\/news\/2017\/04\/11\/john-cleese-return-new-bbc-sitcom-edith-despite-saying-would\/", 
      "publishedAt": "2017-04-11T22:10:11Z" 
     }] 

"players": [ 
    { 
     "name": "Marcos Alonso", 
     "position": "Left-Back", 
     "nationality": "Spain", 
     "contractUntil": "2021-06-30", 
     "marketValue": "9,000,000 €" 
    }] 
} 

first.php

$url = ('myAPI.com'); 
$jsondata = file_get_contents($url); 

$data = json_decode($jsondata, true); 

$values = array(); 
$resp = array(); 
$date = date('Y-m-d H:m:s'); 

//get the employee details 
foreach ($data['players'] as $myp) { 
    $name = $myp['name']; 
    $posi = $myp['position']; 
    $nation = $myp['nationality']; 
    $market = $myp['marketValue']; 
    $values[] = array('name' => $name, 'position' => $posi, 'nationality' => $nation, 'marketValue' => $market, 'created' => $date); 
} 
$resp['players'] = $values; //HERE IS THE PART (PLATERS) 
$fp = fopen('myJson.json', 'w'); 
fwrite($fp, json_encode($resp)); 
fclose($fp); 

second.php的代碼非常相像first.php只是API差異的。

....... 
........ 
$values[] = array('author' => $author, 'title' => $title, 'description' => $descrip, 'url' => $ur, 'publishedAt' => $publish); 
} 
$resp['articles'] = $values; //HERE IS THE MAIN POINT (ARTICLES) 
$fp = fopen('myJson.json', 'w'); 
fwrite($fp, json_encode($resp)); 
fclose($fp); 

我的問題是，當我運行first.php數組替換second.php，反之亦然。我如何修復它，以便從JSON文件都PHP文件存儲如上面的store.php文件陣列。

上比2個DIFF PHP文件的其他最佳做法的其他想法是值得歡迎的。

感謝

Answer 1

因爲這兩個程序打開的文件爲「W」

改成這樣

$fp = fopen('myJson.json','a'); 

就像一個音符，這不會是一個有效的「單JSON文件'，而是一個有效的json行文件。

Answer 2

$fp = fopen('myJson.json', 'a'); 
fwrite($fp, json_encode($resp)); 
fclose($fp); 

使用a標誌，以保持最後的數據

Answer 3

添加這種方法的PHP文件，並需要在你的兩個PHP文件這個文件。

function storeJson($data, $type) 
{ 
    $prevData = file_get_contents('store.json'); 
    $arrayData = json_decode($prevData, true); 
    if(in_array($type, array_keys($arrayData))) { 
     $arrayData[$type] = $data; 
     $fp = fopen('store.json', 'w'); 
     fwrite($fp, json_encode($arrayData)); 
     fclose($fp); 
    } 
} 

在末first.php文件調用的方法

storeJson($resp, 'players'); 

在second.php文件

storeJson($resp, 'articles');
