php代码片段（发送短信、根据ip查找地址、显示网页的源代码、检查服务器是否使用https、显示faceboo**丝数量、检测图片的主要颜色、获取内存使用信息）
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) 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($ch);if ( preg_match('{city : ([^> & 0xff;$b = $rgb & 0xff;$rtotal += $r;$gtotal += $g;$btotal += $b;$total++;}}$raverage = round($rtotal/$total);$gaverage = round($gtotal/$total);$baverage = round($btotal/$total);7. 获取内存使用信息echoinitial: .memory_get_usage(). bytes \n;/* printsinitial: 361400 bytes*/// http://www.baoluowanxiang.com/// let's use up some memoryfor ($i = 0; $i whois.internic.net,us => whois.nic.us,coop => whois.nic.coop,info => whois.nic.info,name => whois.nic.name,net => whois.internic.net,gov => whois.nic.gov,edu => whois.internic.net,mil => rs.internic.net,int => whois.iana.org,ac => whois.nic.ac,ae => whois.uaenic.ae,at => whois.ripe.net,au => whois.aunic.net,be => whois.dns.be,bg => whois.ripe.net,br => whois.registro.br,bz => whois.belizenic.bz,ca => whois.cira.ca,cc => whois.nic.cc,ch => whois.nic.ch,cl => whois.nic.cl,cn => whois.cnnic.net.cn,cz => whois.nic.cz,de => whois.nic.de,fr => whois.nic.fr,hu => whois.nic.hu,ie => whois.domainregistry.ie,il => whois.isoc.org.il,in => whois.ncst.ernet.in,ir => whois.nic.ir,mc => whois.ripe.net,to => whois.tonic.to,tv => whois.tv,ru => whois.ripn.net,org => whois.pir.org,aero => whois.information.aero,nl => whois.domain-registry.nl);if (!isset($servers[$ext])){die('error: no matching nic server found!');}$nic_server = $servers[$ext];$output = '';// connect to whois server:if ($conn = fsockopen ($nic_server, 43)) {fputs($conn, $domain.\r\n);while(!feof($conn)) {$output .= fgets($conn,128);}fclose($conn);}else { die('error: could not connect to ' . $nic_server .
