我正在製作一個電影網站（顯然沒有完成）。我想知道如何從API導出數據並從PHP上的JSON數據中選擇一個數組。在這種情況下，我想輸出電影的標題，但它似乎不起作用。

我得到這個錯誤：

從錯誤中，我知道，我試圖輸出對象，而不是一個字符串，但我不知道如何解決它。

這是我的index.php文件：

<?php 
require_once('includes/variables.php'); 
?> 
<!DOCTYPE html> 
<html> 
    <body> 
    <?php 
     echo $movieNameList->data->movies[1]->id; 
    ?> 
</body> 
</html>

包括/ variables.php文件：

<?php 
$getMovieList = file_get_contents('https://yts.to/api/v2/list_movies.json'); 
$movieNameList = json_decode($getMovieList[0]); 
?>

https://yts.to/api/v2/list_movies.json文件，如果你懶：

這是你的錯誤

<?php 
$getMovieList = file_get_contents('https://yts.to/api/v2/list_movies.json'); 
$movieNameList = json_decode($getMovieList[0]); // <-- Error line 
?>

應該

<?php 
$getMovieList = file_get_contents('https://yts.to/api/v2/list_movies.json'); 
$movieNameList = json_decode($getMovieList); 
?>

的file_get_content的結果是一個簡單的字符串，而不是一個數組

好，f *王謝天謝地：D。我忘記了file_get_contents函數。 –

另外，如何選擇，比如說第二個數組？例如，Bigfoot Country電影。 echo $ movieNameList-> data-> movies [1] - > title;我應該在哪裏改變？ –

使用[1]時，您正在選擇第二個陣列發生記住陣列從[0]開始 – RiggsFolly

確保你正在鍵入正確的鍵名稱。本文參考標題是有效的：

<?php 
$movieNameList->data->movies[1]->title;

你也無論是第二個參數設置爲true解碼JSON作爲數組：

json_decode($getMovieList, true);

或投下屬性的字符串：

echo (string) $object->property;

編輯：

這條線：

$movieNameList = json_decode($getMovieList[0]);

應該是：

$movieNameList = json_decode($getMovieList);

還是一樣的。這裏的問題是我想知道如何選擇一個數組。例如，我想獲得第一部電影的標題，即R.E.M.由MTV。 –

檢查我的答案中的新信息 – user2479930

謝謝大家：D。另外，如何選擇另一個數組？比如，如何選擇大腳鄉村電影？ –

從PHP上的JSON數據中選擇一個arrray
