php文件沒有顯示錯誤

Question

我有PHP文件裏面的wamp服務器。當我在localhost中運行該文件時，會出現如下所示的錯誤。

這是我的PHP文件：

<?php 
$response = array({ 
    "success": [ 
     { 
      "message": "Required field id missing" 
     }, 
     { 
      "message": "successfully created." 
     }, 
     { 
      "message": "Oops! An error occured" 
     } 
    ]} 
); 
  
if (isset($_POST['name']) && isset($_POST['price']) && isset($_POST['description'])) { 
  
    $name = $_POST['name']; 
    $price = $_POST['price']; 
    $description = $_POST['description']; 
  

    require_once __DIR__ . '/db_connect.php'; 
  
     
    $db = new DB_CONNECT(); 
  
    
    $result = mysql_query("INSERT INTO products(name, price, description) VALUES('$name', '$price', '$description')"); 
  
    
    if ($result) { 
         
        $response["success"] = 1; 
        $response["message"] = "Product successfully created."; 
  
        
        echo json_encode($response); 
    } else { 
       
        $response["success"] = 2; 
        $response["message"] = "Oops! An error occurred."; 
  
     
        echo json_encode($response); 
    } 
} else { 
    
    $response["success"] = 0; 
    $response["message"] = "Required field(s) is missing"; 
  
     
    echo json_encode($response); 
} 
?> 

，當我在本地主機上運行它下面的錯誤顯示，

(!) Parse error: syntax error, unexpected '{', expecting ')' in D:\wamp\www\android\create_product.php on line 2

還建議我，如何將localPath在瀏覽器中運行PHP文件。

Answer 1

你的陣列格式是錯誤的，順便說一句，你不需要它，因爲你將消息發送到條件陣列，所以才刪除該部分：

$response = array({ 
    "success": [ 
     { 
      "message": "Required field id missing" 
     }, 
     { 
      "message": "successfully created." 
     }, 
     { 
      "message": "Oops! An error occured" 
     } 
    ]} 
);

你的代碼更好看這個：

• 你不應該在每個條件語句結束後回顯迴應，你可以做一次。
• 另外，當使用isset函數時，您可以根據需要添加儘可能多的參數。

isset($_POST['name']) && isset($_POST['price']) && isset($_POST['description']) 

等於：

isset($_POST['name'],$_POST['price'],$_POST['description']) 

決賽：

if (isset($_POST['name'],$_POST['price'],$_POST['description'])) { 

    $name = $_POST['name']; 
    $price = $_POST['price']; 
    $description = $_POST['description']; 


    require_once __DIR__ . '/db_connect.php'; 


    $db = new DB_CONNECT(); 


    $result = mysql_query("INSERT INTO products(name, price, description) VALUES('$name', '$price', '$description')"); 


    if ($result) { 
     $response["success"] = 1; 
     $response["message"] = "Product successfully created."; 
    } else { 
     $response["success"] = 2; 
     $response["message"] = "Oops! An error occurred."; 
    } 
} else { 
    $response["success"] = 0; 
    $response["message"] = "Required field(s) is missing"; 
} 

echo json_encode($response);
