How to access data in nested Std Object array in PHP - php

Question

I need to access the data: 'hotelID', 'name', 'address1','city' etc. I have the following Std Object array ($the_obj) in PHP that contains the following data:
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
I have tried the following for lets say to access the 'name':
echo $the_obj->HotelListResponse->HotelList->HotelSummary[0]->name;
Also I have tried to print each key and value pairs by using foreach loop but I keep on getting errors. Here is what I tried:
foreach ($the_obj->HotelListResponse->HotelList->HotelSummary[0] as $key => $value){
echo $key.' : '.$value.'<br />';
}
Here are the errors that I get:
Trying to get property of non-object
Warning: Invalid argument supplied for foreach()

Answer 1

Thank you everyone for answering, I have figured out the way to access the 'hotelID', 'name' and all other keys and value pairs in the deepest nest of the array.
I converted the Std Object array to an associative array, then I accessed each of the value by using the foreach loop:
foreach ($the_obj["HotelListResponse"]["HotelList"]["HotelSummary"] as $value){
echo $value["hotelId"];
echo $value["name"];
//and all other values can be accessed
}
To access both (Keys as well as values):
foreach ($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
}

Regarding to #Satya's answer I'd like to show simpler way for Object to array conversion, by using json functions:
$obj = ...
$tmp = json_encode($obj);
$objToArray = json_decode($tmp,true);
This way you can easily access array items. First you can dump structure...

try something like this :
$p=objectToArray($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.'>';
}
}
}
}
}
