Store an array to an array key - php

I'm trying to store an array ($temp) into the $data array, where key is prices.
$data['prices'] = $temp;
However, PHP converts the array into string instead and is throwing me and error.
Notice: Array to string conversion
Is $data = array('prices' => $temp); the only solution?
edit:
I found my mistake. Yes, $data was used previously as a string that's why PHP is converting the input into string.
Problem 2, doing a print_r on $data['prices'] = $xml->result->Prices->Price, shows only 1 set of array. But I am able to retrive 2 sets of result by doing a foreach loop on $data['prices']. Why is that so?
Content of $temp http://pastebin.com/ZrmnKUPB
Let me be more clear..
The full xml object I'm trying to extract information from: http://pastebin.com/AuMJiyrw
I'm only interested in the price array (Price_strCode and Price_strDescription) and store them in $data['prices']. End result something like this:
Array(
[0] => (
[Price_strCode] => 0001
[Price_strDescription] => Gold
)
[1] => (
[Price_strCode] => 0002
[Price_strDescription] => Silver
)
)


Unless you are doing some other array to string conversion elsewhere, the array is actually being stored as another array.
$data['prices'] will be an array, which can be accessed as $data['prices']['key'].


This is not possible, I have been doing this always and it works fine. You must be doing something else somewhere which is causing your array to convert to strong. share your code here

Could not get data from serialized array using unserialize function

I have serialized data and I am using PHP unserialize function which is not working for me. I do not know what is wrong with this string. This is how my serialized data look like. My PHP knowledge is limited so I could not figure out the issue in this data. Can any one help me with this.
s:73:"a:5:{i:0;s:4:"8941";i:1;s:4:"8939";i:2;s:4:"8942";i:3;s:4:"8946";i:4;s:4:"8950";}";

You have a serialized string that contains a serialized array. The string length is 81 not 73.
s:81:"characters in between the first and last quotes and in the example there are 81"
$string = 's:81:"a:5:{i:0;s:4:"8941";i:1;s:4:"8939";i:2;s:4:"8942";i:3;s:4:"8946";i:4;s:4:"8950";}";';
$result = unserialize($string);
Yields the serialized array:
a:5:{i:0;s:4:"8941";i:1;s:4:"8939";i:2;s:4:"8942";i:3;s:4:"8946";i:4;s:4:"8950";}
Unserialize that:
$array = unserialize($result);
Yields the array:
Array
(
[0] => 8941
[1] => 8939
[2] => 8942
[3] => 8946
[4] => 8950
)

PHP using key of one array to access same key position on another array

I've looked at a number of suggestions for this, and they seem to rely on array_combine() which unfortunately is not suitable, as they arrays need to stay separate for other functions.
The arrays are set out as per
Array ( [0] => 3 [1] => 1 [2] => 3 )
Array ( [0] => 194 [1] => 0 [2] => 452 )
When I read in the first array, I get the key as $key and everything works fine.
Whenever I try and access the second array the whole script just whites out the page.
I want the code to work simliar to this ...
$a2value = $a2[$key] => $value;
echo $a2value;
Then I can do SQL lookups using $a2value
Any help would be appreciated

Here Try this
let's suppose two arrays of same number of elements
$a1=[1,2,3];
$a2=[194,0,452];
//A Simple foreach
foreach($a1 as $key=>$a1value){
$a2value=$a2[$key];
//Perform Query here
}
Remember one thing number of elements of both array should always be equal or it will cause an error
If you aren't certain about the size of both arrays then replace the line with this code
$a2value=empty($a2[$key]) ? null : $a2[$key];
Hope this works !!!

Array confusion with square brackets

I am using an API which has a lot of data inside lots of arrays which as you may know can be quite confusing.I am relatively new to API's and this one in particular has no documentation.
My code below is grabbing the recent_games() function which is pulling the whole API then I am using foreach loops to get inside the data.
$games = $player->recent_games();
foreach($games['gameStatistics']['array'] as $key => $gameStatistic) {
$game_date[strtotime($gameStatistic['createDate'])] = $gameStatistic;
}
// order data
krsort($game_date);
foreach ($game_date as $game => $data) {
$statistics[$data] = $data['statistics'];
}
I am getting errors such as illegal offset for:
$statistics[$data] = $data['statistics'];
Is there a way to continue down the nesting of arrays ($game_date) to get to the data that I need?
Let me know if you need more info.
Thanks
EDIT more info:
The first foreach loop at the top loops a unix timestamp key per game. Looks like this:
[1370947566] => Array
(
[skinName] => Skin_name
[ranked] => 1
[statistics] => Array
(
[array] => Array
(
[0] => Array
(
[statType] => stat_data
[value] => 1234
)
[1] => Array
(
[statType] => stat_data
[value] => 1234
)
As you can see its quite nested but I am trying to get to the individual statistics array. I hope that helps?

$statistics[$data] = $data['statistics'];
There is absolutely no way this line is correct.
The right hand side uses $data as if it were an array, indexing into it. The left hand side uses $data as a key into an array. Since the only valid types for keys are strings and integers, $data cannot satisfy the requirements of both expressions at the same time -- it cannot be an array and a string or integer.
It's obvious from the error message that $data is in fact an array, so using it as $staticstics[$data] is wrong. What do you want $statistics to be?

Get value of nested key name in php array

I have been working with parsing some remote JSON with PHP. I have been able to download the JSON and assign it to a variable, and I have used the array functionality with json_decode:
$data = json_decode($remotejson, true);
I have then printed the complete array back to verify the contents of the array:
echo print_r($data);
The array prints back and I can see the keys and values:
[files] => Array
(
[/photogalleryupload.thumbs/1934307_000001.jpg] => Array
(
[source] => derivative
[format] => Thumbnail
[original] => moviefile_1934307.mp4
)
I am trying to get the value of the first nested key name which is "/photogalleryupload.thumbs/1934307_000001.jpg" and assign it to a variable.
For example, I would like the following code:
echo $data['files'][0];
To return this:
/photogalleryupload.thumbs/1934307_000001.jpg
This does not work.
The difficulty I am having is that this value I am trying to return is a 2nd level key name and I have been having trouble finding a way of assigning it to a variable.

$keys = array_keys($data['files'])
$key = $keys[0]

How do I `json_encode()` keys from PHP array?

I have an array which prints like this
Array ( [0] => 1691864 [1] => 7944458 [2] => 9274078 [3] => 1062072 [4] => 8625335 [5] => 8255371 [6] => 5476104 [7] => 6145446 [8] => 7525604 [9] => 5947143 )
If I json_encode($thearray) I get something like this
[1691864,7944458,9274078,1062072,8625335,8255371,5476104,6145446,7525604,5947143]
Why the name is not encoded (e.g 0, 1 , 2 , 3 etc) ? and how should I do to make it appear in the json code?
the full code is below
$ie = 0;
while($ie 10)
{
$genid = rand(1000000,9999999);
$temp[$ie] = $genid ;
$ie++;
}
print_r($temp);
$temp_json = json_encode($temp);
print_r($temp_json);

You can force that json_encode uses an object although you’re passing an array with numeric keys by setting the JSON_FORCE_OBJECT option:
json_encode($thearray, JSON_FORCE_OBJECT)
Then the returned value will be a JSON object with numeric keys:
{"0":1691864,"1":7944458,"2":9274078,"3":1062072,"4":8625335,"5":8255371,"6":5476104,"7":6145446,"8":7525604,"9":5947143}
But you should only do this if an object is really required.

Use this instead:
json_encode((object)$temp)
This converts the array into object, which when JSON-encoded, will display the keys.
If you are storing a sequence of data, not a mapping from number to another number, you really should use array.

Because those are just the indices of the array. If you want to add some kind of name to each element then you need to use an associative array.
When you decode that JSON array though it will come back out to 0, 1, 2, 3 etc.

This is defined behaviour. The array you show is a non-associative, normally indexed array. Its indexes are implicitly numeric.
If you decode the array in PHP or JavaScript, you will be able to access the elements using the index:
$temp_array = json_decode($temp_json);
echo $temp_array[2]; // 9274078
