[php]代码
1. 发送短信调用 textmagic api。// include the textmagic php librequire('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) $ip = '8.8.8.8';$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,curlopt_referer => 'http://' . $_server['http_host'],);curl_setopt_array($ch, $curl_opt);$content = curl_exec($ch);if (!is_null($curl_info)) {$curl_info = curl_getinfo($ch);}curl_close($ch);if ( preg_match('{city : ([^}i', $content, $regs) ) {$city = $regs[1];}if ( preg_match('{state/province : ([^}i', $content, $regs) ) {$state = $regs[1];}if( $city!='' && $state!='' ){$location = $city . ', ' . $state;return$location;}else{return$default;}}3. 显示网页的源代码 $line) {// loop thru each line and prepend line numbersecho line #{$line_num} : . htmlspecialchars($line) .
