Retrieve php array data through index value

As far as I understand, you want to filter this array by the id index and name . To do this you can use the array_filter function of PHP.

Example:

Filtering this array by A220 and name Dipirona

<?php 

    $arr = "..."; //Array que você mandou no exemplo acima

    $novoArray = array_filter($arr, function($item) {
        return $item['id'] == "A220" && $item['name'] == "Dipirona"; 
    });

Result:

Array
(
    [0] => Array
        (
            [id] => A220
            [name] => Dipirona
            [symbol] => R$
            [rank] => 1
            [price_br] => 8.4
            [price_usd] => 2.0
            [total_supply] => 287.0
            [max_supply] => 21000.0
            [last_updated] => 1519152868
        )

)

If you want to get the first index ( $novoArray[0] ), use the command current :

$novoArray = current($novoArray);

So the result will be this:

Array
(
    [id] => A220
    [name] => Dipirona
    [symbol] => R$
    [rank] => 1
    [price_br] => 8.4
    [price_usd] => 2.0
    [total_supply] => 287.0
    [max_supply] => 21000.0
    [last_updated] => 1519152868
)

Just use a forach to read the array I assume your array is called $ arr

<?php
    foreach($arr as $prod){
        echo $prod['id']
        // ai é so chamar a variavel $prod com o indice
    }
?>

Or if you want to directly access without looping

$arr[0]['id']; 
$arr[1]['id'];
