获取JSON数据

方法名称：GetAvaiillabiilliity获取JSON数据

$mySOAP = <<<EOD 
{ 

     "Authentication": { 
      "LoginId": "username", 
      "Password": "password" 

     }, 

    "AvailabilityInput":{ 
     "BookingType":"O", 
     "JourneyDetails":[{ 
      "Origin":"BOM", 
      "Destination":"PNQ", 
      "TravelDate":"10/30/2016" 
     }], 
     "ClassType":"Economy", 
     "AirlineCode":"", 
     "AdultCount":1, 
     "ChildCount":0, 
     "InfantCount":0, 
     "ResidentofIndia":1, 
     "Optional1":"0", 
     "Optional2":"0", 
     "Optional3":"0" 
    } 

} 
EOD; 
// The HTTP headers for the request (based on image above) 
$headers = array(
    'Content-Type: application/json', 
); 
// Build the cURL session 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_POST, TRUE); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $mySOAP); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
// Send the request and check the response 
if (($result = curl_exec($ch)) === FALSE) { 
    die('cURL error: ' . curl_error($ch) . "<br />\n"); 
} else { 
    echo $result; 
} 
curl_close($ch); 
$data = json_decode($result,true); 
$devices = $data['AvailabilityOutput']['AvailableFlights']; 

?>

输出：GetAvailabilityResponse 这是我们从服务器端得到的回应，我想通过我的PHP展现这一点， html代码。

我的PHP代码

<?php 
echo 'Flifht checking'; 
echo '<br><hr>'; 
    foreach ($devices as $device){ 
     echo '<h4>'; 
     echo $device['FlightNumber']; 
     echo '</h4>'; 
    } 
?>

如何获得JSON代码的所有航班信息？那么如何得到这个json数据AvailabilityOutput":{"AvailableFlights":{"OngoingFlights":[{"AvailSegments"。我无法理解深度树结构。

可能重复[php：loop thro ugh json数组]（http://stackoverflow.com/questions/4731242/php-loop-through-json-array） –

在这里，您可能需要执行所有航班。

我将$devices的名称更改为$availableFlights以使示例更易于理解。

$data = json_decode($result, true); 
$availableFlights = $data['AvailabilityOutput']['AvailableFlights']; 

echo 'Flifht checking'; 
echo '<br><hr>'; 

foreach ($availableFlights['OngoingFlights'] as $availableFlight) { 
    foreach ($availableFlight['AvailSegments'] as $availSegment) { 

    echo '<h4>'; 
    echo 'Flight Number: ' . $availSegment['FlightNumber']; 
    echo '</h4>'; 
    echo '<p>Origin: ' . $availSegment['Origin'] . ' - Destination: ' . $availSegment['Destination'] . '</p>'; 

    } 
}

这里的输出是：

Flifht checking

Flight Number: 618

Origin: BOM - Destination: PNQ

Flight Number: 453

Origin: BOM - Destination: HYD

Flight Number: 2822

Origin: HYD - Destination: PNQ

Flight Number: 465

Origin: BOM - Destination: MAA

Flight Number: 2491

Origin: MAA - Destination: PNQ

Flight Number: 339

Origin: BOM - Destination: DEL

Flight Number: 365

Origin: DEL - Destination: PNQ

Flight Number: 463

Origin: BOM - Destination: MAA

Flight Number: 2491

Origin: MAA - Destination: PNQ

而且，一个小窍门：如果你想看到整个JSON树容易，您可以使用此：

echo "<pre>"; 
print_r($availableFlights); 
echo "</pre>";

（我认为这可能有助于理解数据结构）
