利用这段代码,在特定的域名里可获得whois信息。把域名名称作为参数,并显示所有域名的相关信息。
function whois_query($domain) { // fix the domain name: $domain = strtolower(trim($domain)); $domain = preg_replace('/^http:\/\//i', '', $domain); $domain = preg_replace('/^www\./i', '', $domain); $domain = explode('/', $domain); $domain = trim($domain[0]); // split the TLD from domain name $_domain = explode('.', $domain); $lst = count($_domain)-1; $ext = $_domain[$lst]; // You find resources and lists // like these on wikipedia: // // http://de.wikipedia.org/wiki/Whois // $servers = array( "biz" => "whois.neulevel.biz", "com" => "whois.internic.net", "us" => "whois.nic.us", "coop" => "whois.nic.coop", "info" => "whois.nic.info", "name" => "whois.nic.name", "net" => "whois.internic.net", "gov" => "whois.nic.gov", "edu" => "whois.internic.net", "mil" => "rs.internic.net", "int" => "whois.iana.org", "ac" => "whois.nic.ac", "ae" => "whois.uaenic.ae", "at" => "whois.ripe.net", "au" => "whois.aunic.net", "be" => "whois.dns.be", "bg" => "whois.ripe.net", "br" => "whois.registro.br", "bz" => "whois.belizenic.bz", "ca" => "whois.cira.ca", "cc" => "whois.nic.cc", "ch" => "whois.nic.ch", "cl" => "whois.nic.cl", "cn" => "whois.cnnic.net.cn", "cz" => "whois.nic.cz", "de" => "whois.nic.de", "fr" => "whois.nic.fr", "hu" => "whois.nic.hu", "ie" => "whois.domainregistry.ie", "il" => "whois.isoc.org.il", "in" => "whois.ncst.ernet.in", "ir" => "whois.nic.ir", "mc" => "whois.ripe.net", "to" => "whois.tonic.to", "tv" => "whois.tv", "ru" => "whois.ripn.net", "org" => "whois.pir.org", "aero" => "whois.information.aero", "nl" => "whois.domain-registry.nl" ); if (!isset($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 .

TextMagic引入强大的核心API,可轻松将SMS发送到手机。该API是需要付费。
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 = $router->send('Wake up!', array(9991234567), true); // result: Result is: Array ( [messages] => Array ( [19896128] => 9991234567 ) [sent_text] => Wake up! [parts_count] => 1 )
echo "Initial: ".memory_get_usage()." bytes \n"; /* prints Initial: 361400 bytes */ // let's use up some memory for ($i = 0; $i4) Display source code of any webpage——查看任意网页源代码
如果你想查看网页源代码,那么只需更改第二行的URL,源代码就会在网页上显示出。
$line) { // loop thru each line and prepend line numbers echo "Line #{$line_num} : " . htmlspecialchars($line) . " \n"; }Copy after login
function data_uri($file, $mime) { $contents=file_get_contents($file); $base64=base64_encode($contents); echo "data:$mime;base64,$base64"; }
这段代码帮助你查找特定的IP,只需在功能参数上输入IP,就可检测出位置。
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($ch); if ( preg_match('{ City : ([^7) Detect browser language——查看浏览器语言
检测浏览器使用的代码脚本语言。function get_client_language($availableLanguages, $default='en'){ if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) { $langs=explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE']); foreach ($langs as $value){ $choice=substr($value,0,2); if(in_array($choice, $availableLanguages)){ return $choice; } } } return $default; }Copy after login
if ($_SERVER['HTTPS'] != "on") { echo "This is not HTTPS"; }else{ echo "This is HTTPS"; }
function generateCsv($data, $delimiter = ',', $enclosure = '"') { $handle = fopen('php://temp', 'r+'); foreach ($data as $line) { fputcsv($handle, $line, $delimiter, $enclosure); } rewind($handle); while (!feof($handle)) { $contents .= fread($handle, 8192); } fclose($handle); return $contents; }
