function get_url_contents($url){
$crl = curl_init();
$timeout = 5;
curl_setopt ($crl, CURLOPT_URL,$url);
curl_setopt ($crl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($crl, CURLOPT_CONNECTTIMEOUT, $timeout);
$ret = curl_exec($crl);
curl_close($crl);
return $ret;
}
Implement that helper function.
Use it as matt_thomas suggested:
$streams = json_decode(get_url_contents("https://api.twitch.tv/kraken/streams/?game=Overwatch&limit=25&client_id=xxxxxxxxxxxxxxxxxxxxxxxx"));
Then just view what it spits out:
print_r($streams);
