Share several very useful PHP code snippets_PHP Tutorial

调用 TextMagic++ API。
　　// Include the TextMagicPHP lib
　　require('textmagic-sms-api-php/TextMagicAPI.php');
　　// Set the username andpassword information
　　$username = 'myusername';
　　$password = 'mypassword';
　　// Create a new instanceof 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 => $url,
　　CURLOPT_TIMEOUT => 1,
　　CURLOPT_REFERER => 'http://' .$_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
　　$lines = file('http://google.com/');
　　foreach ($lines as$line_num => $line) {
　　// loop thru each line and prepend line numbers
　　echo "Line # {$line_num} : " . htmlspecialchars($line) . "
n";
　　}
　　4. 检查服务器是否使用HTTPS
　　if ($_SERVER['HTTPS']!= "on") {
　　echo "This is not HTTPS";
　　}else{
　　echo "This is HTTPS";
　　}
　　5. 显示Facebook粉丝数量
　　function fb_fan_count($facebook_name){
　　// Example: https://graph.facebook.com/digimantra
　　$data = json_decode(file_get_contents("https://graph.facebook.com/".$facebook_name));
　　echo $data->likes;
　　}
　　6. 检测图片的主要颜色
　　$i = imagecreatefromjpeg("image.jpg");
　　for ($x=0;$x
　　for ($y=0;$y
　　$rgb = imagecolorat($i,$x,$y);
　　$r = ($rgb >> 16) & 0xFF;
　　$g = ($rgb >> & 0xFF;
　　$b = $rgb & 0xFF;
　　$rTotal += $r;
　　$gTotal += $g;
　　$bTotal += $b;
　　$total++;
　　}
　　}
　　$rAverage = round($rTotal/$total);
　　$gAverage = round($gTotal/$total);
　　$bAverage = round($bTotal/$total);
　　7. 获取内存使用信息
　　echo "Initial:".memory_get_usage()." bytes n";
　　/* prints
　　Initial: 361400 bytes
　　*/
　　// let's use up some memory
　　for ($i = 0; $i < 100000;$i++) {
　　$array []= md5($i);
　　}
　　// let's remove half of the array
　　for ($i = 0; $i < 100000;$i++) {
　　unset($array[$i]);
　　}
　　echo "Final:".memory_get_usage()." bytes n";
　　/* prints
　　Final: 885912 bytes
　　*/
　　echo "Peak:".memory_get_peak_usage()." bytes n";
　　/* prints
　　Peak: 13687072 bytes
　　*/
　　8. 使用 gzcompress() 压缩数据
　　$string =
　　"Lorem ipsum dolor sit amet, consectetur
　　adipiscing elit. Nunc ut elit id mi ultricies
　　coaching There is nothing easy. It's a pillow,
　　wisdom or feugiat vestibulum, there is no reason for the price,
　　No one has ever been the owner of a lake before. Thank you very much
　　it is important to follow the coaching process. Some
　　price ullamcorper urn who targeted. And also the mass
　　sed turpis tempor luctus. Curabitur sed nibh eu elit
　　soft homework It is the very home, the consequence of life
　　decorate a, some a now In that big kids
　　the earth to put adipiscing But not my fear, but Lacinia
　　advertise But great unless, adorn in soft in, soft
　　but now Even at the moment the homework is soft.
　　He has no need to fear the Hendrerit Schlesicker
　　not for football. As expected, there is no water to drink from the lake 　　that Euismod urna members.";
　　$compressed = gzcompress($string);
　　echo "Original size: ". strlen($string)."n";
　　/* prints
　　Original size: 800
　　*/
　　echo "Compressed size:". strlen($compressed)."n";
　　/* prints
　　Compressed size: 418
　　*/
　　// getting it back
　　$original = gzuncompress($compressed);
　　9. Use PHP 做Whois 名生
　　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
　　//
　　$servers = array(
　　"biz" =>"whois.neulevel.biz",
　　"com" =>"whois.internic.net",
　　"us" => "whois.nic.us",
　　"coop" =>"whois.nic.coop",
　　"info" =>"whois.nic.info",
　　"name" =>"whois.nic.name",
　　"net" =>"whois.internal.net",
　　"gov" =>"whois.nic.gov",
　　"edu" =>"whois.internic.net",
　　"mil" =>"rs.internic.net",
　　"int" =>"whois.iana.org",
　　"and" => "whois.nic.ac",
　　"ae" =>"whois.uaenic.ae",
　　"at" => "whois.ripe.net",
　　"au" =>"whois.aunic.net",
　　"be" => "whois.dns.be",
　　"bg" =>"whois.ripe.net",
　　"br" =>"whois.registro.br",
　　"bz" =>"whois.belizenic.bz",
　　"ca" => "whois.cira.ca",
　　"cc" => "whois.nic.cc",
　　"ch" => "whois.nic.ch",
　　"cl" => "whois.nic.cl",
　　"cn" =>"whois.cnnic.net.cn",
　　"cz" => "whois.nic.cz",
　　"of" => "whois.nic.de",
　　"fr" => "whois.nic.fr",
　　"hu" => "whois.nic.hu",
　　"ie" =>"whois.domainregistry.ie",
　　"il" =>"whois.isoc.org.il",
　　"in" =>"whois.ncst.ernet.in",
　　"go" => "whois.nic.ir",
　　"mc" =>"whois.ripe.net",
　　"to" =>"whois.tonic.to",
　　"tv" => "whois.tv",
　　"ru" =>"whois.ripn.net",
　　"org" => "whois.pir.org",
　　"aero" =>"whois.information.aero",
　　"nl" => "whois.domain-registry.nl"
　　);
　　if (!isset($servers[$ext])){
　　day('Error: No matching nic server found!');
　　}
　　$nic_server = $servers[$ext];
　　$output = '';
　　// connect to whois server:
　　if ($conn = fsockopen ($nic_server, 43)) {
　　fputs($conn,$domain."rn");
　　while(!feof($conn)) {
　　$output .= fgets($conn,128);
　　}
　　fclose($conn);
　　}
　　else { die('Error: Could not connect to ' . $nic_server. '!'); }
　　return $output;
　　}
　　10. 通过Email发送PHP错误
　　// Our custom error handler
　　function nettuts_error_handler($number, $message, $file, $line,$vars){
　　$email = "
An error ($number) occurred on line
$line and in the file: $file.
$message
";
　　$email .= "
" . print_r($vars, 1) . "
";
　　$headers = 'Content-type: text/html; charset=iso-8859-1' . "rn";
　　// Email the error to someone...
　　error_log($email, 1, 'you@youremail.com',$headers);
　　// Make sure that you decide how to respond to errors (on the user's side)
　　// Either echo an error message, or kill the entire project. Up to you...
　　// The code below ensures that we only "die" if the error was more than
　　// just a NOTICE.
　　if ( ($number !== E_NOTICE) && ($number < 2048) ) {
　　die("There was an error.Please try again later.");
　　}
　　}
　　// We should use our custom function to handle errors.
　　set_error_handler('nettuts_error_handler');
　　// Trigger an error... (vardoesn't exist)
　　echo$somevarthatdoesnotexist;
