PHP how to get value from multidimensional array? - php

Question

I have an array in a class and want to obtain the 'Apple' key value ('iPhone').
I assume a for each loop needs to be used.
How would I go about doing this?
UPDATE: I also need to specify the customerType and productType key values.
class Products {
public function products_list() {
$customerType = 'national';
$productType = 'phones';
$phoneType = 'Apple';
$productsArr = array();
$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'
),
)
);
}
}

Answer 1

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.

Answer 2

If you want single entry:
echo $productsArr[0]['productType']['phones']['Apple']."<br />";
If there are multiple data, you can use foreach:
foreach ($productsArr as $prod){
echo $prod['productType']['phones']['Apple']."<br />";
}

Answer 3

just try
foreach($productsArr[0]['productType']['phones'] as $phones){
echo $phones[$phoneType]; }

Answer 4

foreach($productsArr as $key1 => $data1 ){
if(is_array($data1))
foreach($data1 as $key2 => $data2 ){
if(is_array($data2))
foreach($data2 as $key3 => $data3 ){
if(array_key_exists('Apple', $data3)) {
echo $data3['Apple'] ."\n";
}
}
}
}
