從JSON中提取在線特定值

您好我有一個腳本，它獲取數組中的JSON輸出，但我只想提取名稱字段。它是一個非常實用的HostBill API，我只想打印域頂級域名。我嘗試了所有的辦法，但我收到此錯誤 注意：試圖讓非對象的屬性在C：\ XAMPP \ htdocs中\ hostbill \檢查\的index.php上線22從JSON中提取在線特定值

我不知道代碼有什麼問題。

我需要的輸出是：產品名稱：「.com」; 它來源於此JSON，因爲這「名」：「.COM」，

我的PHP代碼：

<?php 
    $url = 'http://localhost/hostbill/admin/api.php'; 
    $post = array(
     'api_id' => '4c76ed9e1d48cc4f5d56', 
     'api_key' => '2056c9b03cc95ce625b1', 
     'call' => 'getProducts', 
     'id'=>1 
    ); 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_POST, 1); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); 
    $data = curl_exec($ch); 
    curl_close($ch); 
    $return = json_decode($data, true); 
    print_r($return); 
    $product_name = $return->name; 
    echo "Product Name: ".$product_name; 
?>

Hostbill JSON響應示例：

     "products": {

什麼是'的print_r（$返程）輸出;'？ – aldrin27

可能的重複[如何從JSON提取數據與PHP？]（http://stackoverflow.com/questions/29308898/how-do-i-extract-data-from-json-with-php） –

產品均array ，因此請使用foreach遍歷所有產品。

foreach($return['products'] AS $product){ 
    echo "Product Name: ".$product['name']; 
}

您還應該檢查API響應是否有效。如果API不響應數組產品或響應空的響應，則會出錯。這將做到這一點。

if(isset($return['products']) && is_array($return['products'])){ 
    foreach($return['products'] AS $product){ 
     echo "Product Name: ".$product['name']; 
    } 
}

提取特定的類別

爲了讓只有特定的產品，只要使用if聲明。例如將產品從category_id1和type9：

foreach($return['products'] AS $product){ 
    if($product['category_id'] == 1 && $product['type'] == 9){ 
     echo "Product Name: ".$product['name']; 
    } 
}

它的工作原理但只能從特定類別提取嗎？在JSON中有兩個字段1是type，第二個是category_id –

是的。看到我編輯的答案。 –

注意：第22行的C：\ xampp \ htdocs \ hostbill \ check \ index.php中的未定義索引：category_id –

你會得到錯誤，因爲它不是一個對象。這是一個數組。

所以它應該是：

foreach($return['products'] as $key => $product){ 
    echo "Product Name: ". $product['name']; 
}
