Error working with Object array nested inside a json

Hello everyone.

please I have problem with printing out a value from inside an array of a nested json. ive tried several ways its always returns "index not define".
here is the code .

$valr= "https://ice3.com/api/v1/orderbook/ticker";    ////////////////////////////source

	 $valrGet =  file_get_contents($valr);
	 $valrD =  json_decode($valrGet, true);
	 $valrSell = ["ask"] ["price"];
                 

Here is the structure of the json from the source :

{"errors":false,"response":{"entities":[{"pair_id":3,"pair_name":"BTC\/ZAR","ask":{"price":"179382.54","amount":"0.05357142"},"bid":{"price":"177229.4286563","amount":"0.0011"}},{"pair_id":4,"pair_name":"BTC\/NGN","ask":{"price":"8890000.00","amount":"0.10"},"bid": 

my target is to  output  the value of  ("price") from "pair_name"   BTC\/ZAR

please help. Thanks in advance

However, using the string just as far as the the first entity

$valrD = json_decode(valrGet, true);
echo '<pre>$valrD = ', print_r($valrD, 1), '</pre>';

gives

therefore

$target = 'BTC/ZAR';

foreach ($valrD['response']['entities'] as $k => $ents) {
    if ($ents['pair_name'] == $target) {
        echo "$target asking price : {$ents['ask']['price']}<br>";
        break;
    }
}

outputs "BTC/ZAR asking price : 179382.54"
