cURL call not working with no errors visible (WampServer 3)

I use curl with the Riot API. Everything is working fine on my live server but isn't in local. The curl extension is enabled in WampServer and I don't get any error messages, it's just a blank page.

Here's my code even if it's not actually relevant.

<?php 
    $private_key = "XXX";
    function summoner_name($summoner, $server, $private_key) {
        $summoner_encoded = rawurlencode($summoner);
        $summoner_lower = strtolower($summoner_encoded);
        $curl_url = 'https://' . $server . '.api.pvp.net/api/lol/' . $server . '/v1.4/summoner/by-name/' . $summoner . '?api_key='.$private_key;
        $curl = curl_init($curl_url);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $result = curl_exec($curl);
        curl_close($curl);
        return $result;
    }

    function summoner_info_array_name($summoner) {
        $summoner_lower = mb_strtolower($summoner, 'UTF-8');
        $summoner_nospaces = str_replace(' ', '', $summoner_lower);
        return $summoner_nospaces;
    }

    $summoner = "Test";
    $server = "euw";
    $summoner_info = summoner_name($summoner, $server, $private_key);
    $summoner_info_array = json_decode($summoner_info, true);
    $summoner_info_array_name = summoner_info_array_name($summoner);
    $summoner_id = $summoner_info_array[$summoner_info_array_name]['id'];
    $summoner_name_display = $summoner_info_array[$summoner_info_array_name]['name'];
    $summoner_icon = $summoner_info_array[$summoner_info_array_name]['profileIconId'];
    echo '<img src="http://ddragon.leagueoflegends.com/cdn/6.9.1/img/profileicon/'.$summoner_icon.'.png" /><br/><hr>'.$summoner_name_display;
?>

And here's my phpinfo() for curl extension.
Thanks in advance! enter image description here.

So, first, as @MaksimVolkob pointed out, and as we discussed in the comments, the first step to resolving these errors is to see what the error message actually is. curl_error() will give you this information.

Specifically, you're getting an SSL/TLS error:

SSL certificate problem: unable to get local issuer certificate' (length=63)

If you don't care about security (I do not recommend this for production applications, ever.), you can disable the SSL verification step that is failing:

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

The better way is to fix your CA certificate information by setting CURLOPT_CAINFO. This blog post explains this pretty well.

Edit: As OP discovered, this question has more specifics about getting cURL to recognize the proper CA certificate.

You can always call curl_getinfo() and curl_error() functions to check the problems on latest curl query.

Like this:

$result = curl_exec($curl);
if ($result === false) {
    echo "Something is wrong here!\n".var_export(curl_error($curl), true)
         . "\nQuery:".var_export(curl_getinfo($curl), true); exit();
}
