Creating new array from looping another array - php

Question

I need to tidy up an array. And gather all similar information together.
This is going to be a huge order that I'm bringing to the table, however, it's well beyond my skill set and I've been trying to fix it for 3 days.
The message comes from a webservice, which i have absolutely no control over the output/response.
I need to be able to put all the info
But the following (i know its big sorry) is the SOAP object reply: (this has been reduced as well) eek.

TL;DR
Each hotel has 2 rooms with ids. Each of these 2 id's are seperated by dates, but are in the different parts of the array :(
[Hotel A]
HotelA RoomId = 01
Date = 12-08-2011
[Hotel A]
HotelA RoomId = 02
Date = 12-08-2011
[Hotel B]
HotelB RoomId = 01
Date = 12-08-2011
[Hotel B]
HotelB RoomId = 02
Date = 12-08-2011
[Hotel A]
HotelA RoomId = 01
Date = 13-08-2011
[Hotel A]
HotelA RoomId = 02
Date = 13-08-2011
[Hotel B]
HotelB RoomId = 01
Date = 13-08-2011
[Hotel B]
HotelB RoomId = 02
Date = 13-08-2011
I want to be able to put them into an array as such:
[Hotel A]
HotelA RoomId = 01
Date 12-08-2011
Date 13-08-2011
HotelA RoomId = 02
Date 12-08-2011
Date 13-08-2011
etc
Please help. I've been pulling my hair out :(
Here is an example of what ive tried:
$hotelinfo = array();
$k=0;
for($i = 0; $i < count($result->RoomInformation); $i++)
{
$flag = false;
$HotelObj = $result->RoomInformation[$i];
$HotelName = $result->RoomInformation[$i]->RoomInformationExtend->RoomDetails->Description;
$HotelId = $result->RoomStays->RoomStay[$i]->RoomInformation->RoomDetails->RoomId;
//$hotelinfo[$i][$HotelName] = array();
$hotelinfo[count($hotelinfo)] = array();
$hotelinfo[count($hotelinfo)][$HotelName] = array();
for($c = 0; $c < count($result->RoomInformation); $c++)
{
$thishotelObj = $result->RRoomInformation[$c];
$thisHotelName = $thishotelObj->RoomInformationExtend->RoomDetails->Description;
$thisHotelId = $thishotelObj->TPA_Extensions->RoomDetails->RoomId;
if($thisHotelName == $HotelName & $thisHotelId == $HotelId){
$hotelinfo[$i][$HotelName][$c] = $HotelName;
$hotelinfo[$i][$HotelName][$c] = $thisHotelName;
$i++;
}
}
}
was i even going in thr correct direction with this?

Answer 1

I suppose such a foreach loop would be sufficient. PHP doesn't check the existence of array members on updating, so it would just add the needed keys.
$HotelRooms = array();
$foreach($result as $r)
{
$HotelName = $r->RoomInformationExtend->RoomDetails->Description;
$HotelRooms[$HotelName][$r->RoomInformationExtend->RoomDetails->RoomId][] = $r->Details->EffectiveDate
}

Answer 2

When you do this...
$hotelinfo[count($hotelinfo)] = array();
$hotelinfo[count($hotelinfo)][$HotelName] = array();
You're actually adding two elements to $hotelinfo. For instance, if there were 4 elements in it already, the first line would set index 4, which is a new index (the existing ones are 0, 1, 2, and 3), thus adding an element.
Now that the first line is done, the number of elements in $hotelinfo is 5, and thus the second line sets index 5 - but index 5 corresponds to the next empty slot, and thus a second element is added (for an end result of indices 0-5 being set, with 4 and 5 both new).
Judging from your code, I don't think this is what you intended.
Going the extra mile (or two)...
I think what you might want to do first is get the data into a more usable format - grouped first by hotel, and then by room ID. So, let's do that:
$hotelInfo = array();
foreach($result->RoomInformation as $roomInfo) {
$hotelName = $roomInfo->RoomInformationExtend->RoomDetails->Description;
if(!isset($hotelInfo[$hotelName])) {
$hotelInfo[$hotelName] = array();
}
$thisHotel = $hotelInfo[$hotelName];
$roomId = $roomInfo->RoomInformationExtend->RoomDetails->RoomId;
if(!isset($thisHotel[$roomId])) {
$thisHotel[$roomId] = array();
}
$thisRoom = $thisHotel[$roomId];
Okay, so now we have a $thisRoom object that we can fill in info for. If a different item in the list we're going through already created an object for a particular hotel+room combination, we just get that already-created one instead of making a new one.
Now, we'll add any relevant information is the current item of data to our room object:
if(isset($roomInfo->Details)) {
if(isset($roomInfo->Details->EffectiveDate)) {
// "$foo[] = bar" appends 'bar' to the array '$foo'
$thisRoom[] = $roomInfo->Details->EffectiveDate;
}
if(isset($roomInfo->Details->RoomRate)) {
if(isset($roomInfo->Details->RoomRate->EffectiveDate)) {
$thisRoom[] = $roomInfo->Details->RoomRate->EffectiveDate;
}
}
}
}
After you've done this, you'll wind up with a structure in $hotelInfo that looks like this:
array(
['Hotel Alpha'] => array(
[1860] => array('2011-08-12', '2011-08-13'),
[1861] => array('2011-08-12', '2011-08-13')
),
['Hotel Beta'] => array(
[1226] => array('2011-08-12', '2011-08-13'),
[1227] => array('2011-08-12', '2011-08-13')
)
)
Which should be much easier to work with, and a lot closer to what you seem to be wanting.
