我需要访问数据:'hotelID','name','address1','city'等。我在PHP中有以下Std Object数组($ the_obj),其中包含以下数据:
object(stdClass)[1]
public 'HotelListResponse' =>
object(stdClass)[2]
public 'customerSessionId' => string '0ABAAA87-6BDD-6F91-4292-7F90AF49146E' (length=36)
public 'numberOfRoomsRequested' => int 0
public 'moreResultsAvailable' => boolean false
public 'HotelList' =>
object(stdClass)[3]
public '@size' => string '227' (length=3)
public '@activePropertyCount' => string '227' (length=3)
public 'HotelSummary' =>
array (size=227)
0 =>
object(stdClass)[4]
public 'hotelId' => 112304
public 'name' => La Quinta Inn and Suites Seattle Downtown
public 'address1' => 2224 8th Ave
public 'city' => Seattle
public 'stateProvinceCode' => WA
public 'postalCode' => 98121
public 'countryCode' => US
public 'airportCode' => SEA
public 'propertyCategory' => 1
public 'hotelRating' => 2.5
我尝试了以下内容,让我们来访问“名称”:
echo $the_obj->HotelListResponse->HotelList->HotelSummary[0]->name;
此外,我尝试使用foreach循环打印每个键和值对,但我一直在收到错误。这是我尝试过的:
foreach ($the_obj->HotelListResponse->HotelList->HotelSummary[0] as $key => $value){
echo $key.' : '.$value.'<br />';
}
以下是我收到的错误:

关于@Satya的答案,我想通过json
函数显示更简单的对象转换方式:
$obj = ...
$tmp = json_encode($obj);
$objToArray = json_decode($tmp,true);
这样您就可以轻松访问数组项。首先你可以转储结构...

感谢大家的回答,我已经找到了访问'hotelID','name'以及阵列最深处的所有其他键和值对的方法。
我将Std Object数组转换为关联数组,然后使用foreach循环访问每个值:
foreach ($the_obj["HotelListResponse"]["HotelList"]["HotelSummary"] as $value){
echo $value["hotelId"];
echo $value["name"];
//and all other values can be accessed
}
要同时访问(键和值):
foreach ($the_obj["HotelListResponse"]["HotelList"]["HotelSummary"] as $key=>$value){
echo $key.'=>'.$value["hotelId"];
echo $key.'=>'.$value["name"];
//and all other keys as well as values can be accessed
}

尝试这样的事情:
$p=objectToArray($result);
recurse($p);
}
function objectToArray( $object )
{
if( !is_object( $object ) && !is_array( $object ) )
{
return $object;
}
if( is_object( $object ) )
{
$object = get_object_vars( $object );
}
return array_map( 'objectToArray', $object );
}
function recurse ($array)
{
//statements
foreach ($array as $key => $value)
{
# code...
if( is_array( $value ) )
{
recurse( $value );
}
else
{ $v=$value;
$v=str_replace("’",'\'',strip_tags($v));
$v=str_replace("–",'-',$v);
$v=str_replace("‘",'\'',strip_tags($v));
$v=str_replace("“",'"',strip_tags($v));
$v=str_replace("”",'"',strip_tags($v));
$v=str_replace("–",'-',strip_tags($v));
$v=str_replace("’",'\'',strip_tags($v));
$v=str_replace("'",'\'',strip_tags($v));
$v=str_replace(" ",'',strip_tags($v));
$v=html_entity_decode($v);
$v=str_replace("&",' and ',$v);
$v = preg_replace('/\s+/', ' ', $v);
if($key=="image")
{
if(strlen($v)==0)
{
echo '<'.$key .'>NA</'.$key.'>';
}
else
{
echo '<'.$key .'>'. trim($v) .'</'.$key.'>';
}
}
}
}
}
