For people who searched for php multidimensional array get values and actually want to solve problem comes from getting one column value from a 2 dimensinal array (like me!), here's a much elegant way than using foreach, which is array_column

For example, if I only want to get hotel_name from the below array, and form to another array:

$hotels = [
    [
        'hotel_name' => 'Hotel A',
        'info' => 'Hotel A Info',
    ],
    [
        'hotel_name' => 'Hotel B',
        'info' => 'Hotel B Info',
    ]
];

I can do this using array_column:

$hotel_name = array_column($hotels, 'hotel_name');

print_r($hotel_name); // Which will give me ['Hotel A', 'Hotel B']

For the actual answer for this question, it can also be beautified by array_column and call_user_func_array('array_merge', $twoDimensionalArray);

Let's make the data in PHP:

$hotels = [
    [
        'hotel_name' => 'Hotel A',
        'info' => 'Hotel A Info',
        'rooms' => [
            [
                'room_name' => 'Luxury Room',
                'bed' => 2,
                'boards' => [
                    'board_id' => 1,
                    'price' => 200
                ]
            ],
            [
                'room_name' => 'Non Luxy Room',
                'bed' => 4,
                'boards' => [
                    'board_id' => 2,
                    'price' => 150
                ]
            ],
        ]
    ],
    [
        'hotel_name' => 'Hotel B',
        'info' => 'Hotel B Info',
        'rooms' => [
            [
                'room_name' => 'Luxury Room',
                'bed' => 2,
                'boards' => [
                    'board_id' => 3,
                    'price' => 900
                ]
            ],
            [
                'room_name' => 'Non Luxy Room',
                'bed' => 4,
                'boards' => [
                    'board_id' => 4,
                    'price' => 300
                ]
            ],
        ]
    ]
];

And here's the calculation:

$rooms = array_column($hotels, 'rooms');
$rooms = call_user_func_array('array_merge', $rooms);
$boards = array_column($rooms, 'boards');

foreach($boards as $board){
    $board_id = $board['board_id'];
    $price = $board['price'];
    echo "Board ID is: ".$board_id." and price is: ".$price . "<br/>";
}

Which will give you the following result:

Board ID is: 1 and price is: 200
Board ID is: 2 and price is: 150
Board ID is: 3 and price is: 900
Board ID is: 4 and price is: 300

TL;DR

$result = call_user_func_array('array_merge', $array);

Credit: How to "flatten" a multi-dimensional array to simple one in PHP?

In your use case, you should use it like this:

<?php
$array = [
    'car' => [
        'BMW' => 'blue',
        'toyota' => 'gray'
        ],
    'animal' => [
        'cat' => 'orange',
        'horse' => 'white'
        ]
    ];
$result = call_user_func_array('array_merge', $array);
$result = array_values($result);

//$result = ['blue', 'gray', 'orange', 'white']

Assuming $array contains your data, the following code will do it.

$result = array();
foreach($array as $a){
    foreach($a as $l){
        list($ab, $it) = explode(",", $l, 2);
        $ab = substr($ab, strlen("Ability:"));
        $it = substr($it, strlen("Itemname:"));
        $result[] = array(
            'Ability' => $ab,
            'Itemname' => $it
        );
    }
}

PHP :

foreach( $this->analyze_types as $key => $value) {
  echo $key; // output 1 and 226
  echo $value['level']; // output 4 and -1
}

The thing that is probably tripping you up is that suitability is an array of arrays not just an array so in an example where you want to get the species_name property of the first second top level element you would use something like

$array[1]["suitability"][0]["species_name"];

It's worth noting that your first array does not contain a "suitability" value so that would not be able to be accessed. In a foreach loop you could use a construct similar to this:

foreach($array as $value){
    if (isset($value["suitability"])){
        echo $value["suitability"][0]["species_name"];
    }
}

You can use array_column like as

echo array_column($myoptions,1,0)['3 days'];//72

Demo

I have created a function that you can more or less give it any product and it will return the key and value from the array

<?php

class Products
{

    public function products_list()
    {

        $customerType = 'national';
        $productType = 'phones';
        $phoneType = 'Apple';
        $productsArr[] = array(
            'customerType' => 'national', 'productType' => array(
                'phones' => array(
                    'Apple' => 'iPhone',
                    'Sony' => 'Xperia',
                    'Samsung' => 'Galaxy'
                ),
                'cases' => array(
                    'leather' => 'black',
                    'plastic' => 'red',
                ),
            ),
            'international' => array(
                'phones' => array(
                    'BlackBerry' => 'One',
                    'Google' => 'Pixel',
                    'Samsung' => 'Note'
                ),
                'cases' => array(
                    'leather' => 'blue',
                    'plastic' => 'green'
                ),
            )
        );

        echo $this->get_value($phoneType, $productsArr) .'<br>';
        echo $this->get_value($customerType, $productsArr) .'<br>';
        echo $this->get_value($productType, $productsArr) .'<br>';
    }

    function get_value($product, array $products)
    {
        $iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($products), RecursiveIteratorIterator::CHILD_FIRST);

        foreach ($iterator as $key => $value) {
            if (is_string($value) && ($key == $product)) {
                return 'key ->' . $key .' value ->'.$value;
            }
        }
        return "";
    }
}

$phone_products = new Products();


$phone_products->products_list();

To use it within the class just call

$this->get_value($phoneType, $productsArr);

from without the class call

$phone_products = new Products();



echo ($phone_products->get_value($phoneType, $productsArr));
//output: key ->Apple value ->iPhone

NB: $phoneType, $productsArr will either be defined the methods they are being used in or passed from other methods or define global variables within the class.
