1. 发送短信调用 TextMagic API。// Include the TextMagic PHP lib require(''textmagic-sms-api-php/TextMagicAPI.php''); // Set the username and password information $username = ''myusername''; $password = ''mypassword''; // Create a new instance of TM $router = new TextMagicAPI(array( ''username'' => $username, ''password'' => $password )); // Send a text message to ''999-123-4567'' $result = $router->send(''Wake up!'', array(9991234567), true); // result: Result is: Array ( [messages] => Array ( [19896128] => 9991234567 ) [sent_text] => Wake up! [parts_count] => 1 ) 2. 根据IP查找地址function detect_city($ip) { $default = ''UNKNOWN''; if (!is_string($ip) || strlen($ip) < 1 || $ip == ''127.0.0.1'' || $ip == ''localhost'') $ip = ''8.8.8.8''; $curlopt_useragent = ''Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)''; $url = ''http://ipinfodb.com/ip_locator.php?ip='' . urlencode($ip); $ch = curl_init(); $curl_opt = array( CURLOPT_FOLLOWLOCATION => 1, CURLOPT_HEADER => 0, CURLOPT_RETURNTRANSFER => 1, CURLOPT_USERAGENT => $curlopt_useragent, CURLOPT_URL => $url, CURLOPT_TIMEOUT => 1,
