使用cURL而不是file_get_contents

Question

My web host does not support file_get_contents for security reasons but does support the use of cURL. Can anyone tell me now I would convert this short code using curl? I've been trying for days with no luck so any help would be greatly appreciated!

<?php
$json_string = file_get_contents("http://api.wunderground.com/api/b2b4a1ad0a889006/geolookup 
/conditions/q/IA/Cedar_Rapids.json");
$parsed_json = json_decode($json_string);
$location = $parsed_json->{'location'}->{'city'};
$temp_f = $parsed_json->{'current_observation'}->{'temp_f'}; 
echo "Current temperature in ${location} is: ${temp_f}
";
?>

I recommend you use socket

<?php
$fp = stream_socket_client("tcp://api.wunderground.com:80", $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br />
";
} else {
    fwrite($fp, "GET /api/b2b4a1ad0a889006/geolookup/conditions/q/IA/Cedar_Rapids.json HTTP/1.0
Host: api.wunderground.com
Accept: */*

");
    while (!feof($fp)) {
        echo json_decode(fgets($fp));
    }
    fclose($fp);
}
?>
