Extract Data from Multidem array - php

I have been trying to extract the following data for each student from a large multidimensional array (Shown further down)
Data -> gender,
Data -> grade,
Data -> name -> first,
Data -> name -> last,
Data -> name -> middle,
Data -> student_number,
Data -> ID
I have tried various options through searching including Slice, Splice, and a for loop.
Every attempt has been met with failure on all or some of the data. I have never been able to get to the 3rd nested data of First, Middle, and Last name.
How can I take a large multidem array like this, and extract the data listed above in a foreach loop so I can import it into a database? I feel like it is alot simpler than I am making it. I have not included any code as I have yet to have anything that seems remotely useful.
Here is a sample array below. Thanks!
Array

[credentials] => Array

The easiest approach might be to extract the nested data arrays and loop that:
foreach(array_column($array['data'], 'data') as $data) {
echo $data['gender'];
echo $data['name']['first'];
}
If schools is variable length then you'll need to loop that or implode(', ', $data['schools']).

Amazon MWS: Accessing Array of Matching Products

I am Working with MWS for the first time and hoping to create a program that uses the ListMatchingProducts request to average out the prices of every product that matches a query.
It should be a very simple program, but I am having trouble retrieving data.
First I make the call and get amazon's xml sheet, Then I convert the xml to an array.
Print_R shows that the array looks something like this:
Array ( [ListMatchingProductsResult] => Array ( [Products] => Array ( [Product] => Array ( [0] => Array ( [Identifiers] => Array ( [MarketplaceASIN] => Array ( [MarketplaceId] => ATVPDKIKX0DER [ASIN] => 0786866020 ) ) [AttributeSets] => Array ( [ItemAttributes] => Array ( [Author] => Array ( [0] => Stephen C. Lundin [1] => Harry Paul [2] => John Christensen ) [Binding] => Hardcover [Brand] => Hyperion [Color] => White [Creator] => Ken Blanchard [Edition] => 1 [Feature] => Great product! [ItemDimensions] => Array ( [Height] => 8.25 [Length] => 5.50 [Width] => 0.00 [Weight] => 0.54 ) [IsAdultProduct] => false [Label] => Hyperion [Languages] => Array ( [Language] => Array ( [0] => Array ( [Name] => english [Type] => Published ) [1] => Array ( [Name] => english [Type] => Original Language ) [2] => Array ( [Name] => english [Type] => Unknown ) ) ) [ListPrice] => Array ( **[Amount] => 21.00** [CurrencyCode] => USD ) [Manufacturer] => Hyperion [ManufacturerMaximumAge] => 1188.0 [ManufacturerMinimumAge] => 156.0 [NumberOfItems] => 1 [NumberOfPages] => 110 [PackageDimensions] => Array ( [Height] => 0.65 [Length] => 8.60 [Width] => 5.65 [Weight] => 0.58 ) [PackageQuantity] => 1 [PartNumber] => 9780786866021 [ProductGroup] => Book [ProductTypeName] => ABIS_BOOK [PublicationDate] => 2000-03-08 [Publisher] => Hyperion [ReleaseDate] => 2000-03-08 [SmallImage] => Array ( [URL] => http://ecx.images-amazon.com/images/I/51cHo55tbOL._SL75_.jpg [Height] => 75 [Width] => 47 ) [Studio] => Hyperion [Title] => Fish: A Proven Way to Boost Morale and Improve Results ) ) [Relationships] => Array ( ) [SalesRankings] => Array ( [SalesRank] => Array ( [0] => Array ( [ProductCategoryId] => book_display_on_website [Rank] => 4629 ) [1] => Array ( [ProductCategoryId] => 1043856 [Rank] => 2 ) [2] => Array ( [ProductCategoryId] => 2635 [Rank] => 7 ) [3] => Array ( [ProductCategoryId] => 2637 [Rank] => 18 ) ) ) ) [1] ...
I am trying to access the amount part of the array, as this is the price of the object. Eventually, I will need to access the amount of each product and so a loop will likely come into play, but right now i cannot even access one products sales amount.
Here is the code I have been trying
$value = $array->ListMatchingProductsResult->Products->Product[0]->ListPrice->Amount;
print_r($value);
And it is not working. Even calling print_r on $array->ListMatchingProductsResult is not printing an array.
Any help is greatly appreciated!
Thanks,
Matt
You are almost there. Whatever method you are using to convert the XML to a PHP array however, does just that: It creates an associative array of things, not an object. That is why you cannot access it through the ->element operator, but need to use array indexes ['element']
$value = $array['ListMatchingProductsResult']['Products']['Product'][0]['ListPrice']['Amount'];
If you're ever wondering why you're not getting something back, you can successily shorten above expresion until you do. So if a print_r(...) on above expression returns nothing, just remove one square bracket at a time from that print_r until you do get something back. You then know that the last bracket you removed was the culprit.
Array (
[ListMatchingProductsResult] => Array (
[Products] => Array (
[Product] => Array (
[0] => Array (
[Identifiers] => Array (
[MarketplaceASIN] => Array (
[MarketplaceId] => ATVPDKIKX0DER
[ASIN] => 0786866020
)
)
[AttributeSets] => Array (
[ItemAttributes] => Array (
[Author] => Array (

[2] => John Christensen

[Binding] => Hardcover

[Languages] => Array (

[1] => Array (

[Name] => english
[Type] => Unknown
)
)
)
[ListPrice] => Array (
[Amount] => 21.00
[CurrencyCode] => USD
)
[Manufacturer] => Hyperion
...
BTW, using <pre>...</pre> is helpful when trying to make sense of print_r() or var_dump().
P.S. You owe me a new space key.
Here is an sdk library that uses the ListMatchingProducts of Amazon MWS. You will be able to get the info in accessing info required.
https://github.com/choomz/amazon-mws-sdk/blob/master/search/src/MarketplaceWebServiceProducts/Samples/ListMatchingProductsSample.php
To show php errors have this set in your php.in
display_errors = On
You can also give this on top of the php script
ini_set('error_reporting', E_ALL);
ini_set('display_errors', 'On');

How to insert a new values pair in an associative array in PHP?

I've an associative array. I am attempting to create each sub array within a loop and insert it into a multidimensional array. Google suggested using array_merge, but after using 'print_r' on the multidimensional array with the code below, only the last sub-array is being displayed.

I tried lot of tricks but couldn't get the desired array format. Can any one help me in this to get the desired array? Thanks in advance.
$arr = array(); //filled with data
$rating = array(); //filled with rates
foreach ( $rating as $key =>$rate ) {
$arr['data'][ $key ]['rating'] = $rate;
}
<?php
$arr=Array(
'data'=>Array(
0=>Array('candidate'=>Array()),
1=>Array('candidate'=>Array())
)
);
$rating=Array(7,5);
foreach($rating as $key=>$val){
$arr['data'][$key]['rating']=$val;
}
print_r($arr);
Returns:
Array
(
[data] => Array
(
[0] => Array
(
[candidate] => Array
(
)
[rating] => 7
)
[1] => Array
(
[candidate] => Array

[rating] => 5
)

PHP get facebook posts

$data = file_get_contents("https://graph.facebook.com/246179452202174/posts?access_token=TOKEN");
$data = json_decode($data, true);
print_r(array_values($data));
That's my code. It's simple. I can see the data and when I visit the link, it gives me the same info. So that works perfect. Underneath there's some outputs from the api.

When I try to echo $data or maybe $data[1] or something like it, it wont work. Also removing array_values gives me a output of "Array" or "ArrayArray".
So how may I print out the data from the api? It wont work, also; how may I fetch the image? I'd like to print the title of the post, and the image. As a link for a feed at my site.

Since 5.5, you can use in this case array_column:
$creators = array_column($data['values'],'creator');
This will create an array of creators:
$creators = array();
foreach($data['values'] as $value) {
$creators[] = $value['creator'];
}
// An array containing the creator information
var_dump($creators);

Loop through a JSON decoded array

I am using randonuser API to generate dummy images. The API returns JSON that I have used json_decode to decode and using print_r, I got the array below:

and so on.
I just need the large key value under parent picture. How do I loop through it using a foreach statement?
Just access it as you normally would:
$data = json_decode('that json string', true);
foreach($data['results'] as $value) {
echo $value['user']['picture']['large'];
}
Use json_decode($var, true), then you'll have an array, and looping will be easier.
