You put `var_dump($me);` outside the function `compare_plus` scope - that is the reason it null. Aside, you question is unclear... — dWinder, Sep 16 '18 at 13:30
when $me put in function filter dos not work i need a new code if possible — puriya, Sep 16 '18 at 13:37
I am sorry but I still don't understand what you need - please try to edit you question. Add example (by code and not picture) of the `$coins` — dWinder, Sep 16 '18 at 14:04

Now the question is much clearer.

You can use array_filter to obtain that.

Consider the following code:

$tick = file_get_contents('https://api.coinmarketcap.com/v2/ticker');
$data = json_decode($tick, TRUE);

$symbols = array("BTC", "ETH", "LTC");
$filtered = array_filter($data['data'], function($elm) use ($symbols){
    return (in_array($elm['symbol'], $symbols));
});
echo print_r($filtered, true);

I filtered by symbol but you can change the filter field by changing the (in_array($elm['symbol'], $symbols)) to other field then symbol
