1) Whois query using PHP ——利用PHP获取Whois请求
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。
复制代码 代码如下: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:
//
// <a href="http://de.wikipedia.org/wiki/Whois">http://de.wikipedia.org/wiki/Whois</a>
//
$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",

"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 . '!'); }
return $output;
}
2) Text messaging with PHP using the TextMagic API ——使用TextMagic API 获取PHP Test信息
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。
复制代码 代码如下:
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 = $router->send('Wake up!', array(9991234567), true);
// result: Result is: Array ( [messages] => Array ( [19896128] => 9991234567 ) [sent_text] => Wake up! [parts_count] => 1 )
3) Get info about your memory usage——获取内存使用率
这段代码帮助你获取内存使用率。
复制代码 代码如下:
echo "Initial: ".memory_get_usage()." bytes \n";
/* prints
Initial: 361400 bytes
*/
// let's use up some memory
for ($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
*/
4) 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。
复制代码 代码如下:<?php // display source code $lines = file('http://google.com/'); foreach ($lines as $line_num => $line) {
// loop thru each line and prepend line numbers
echo "Line #{$line_num} : " . htmlspecialchars($line) . "
\n";
}
5) Create data uri's——创建数据uri
通过使用此代码，你可以创建数据Uri，这对在HTML/CSS中嵌入图片非常有用，可帮助节省HTTP请求。
复制代码 代码如下:
function data_uri($file, $mime) {
$contents=file_get_contents($file);
$base64=base64_encode($contents);
echo "data:$mime;base64,$base64";
}
6) Detect location by IP——通过IP检索出地理位置
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。
复制代码 代码如下:
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 $default; } }
7) Detect browser language——查看浏览器语言
检测浏览器使用的代码脚本语言。
复制代码 代码如下:function get_client_language($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 $default;
}
8) Check if server is HTTPS——检测服务器是否是HTTPS
复制代码 代码如下:if ($_SERVER['HTTPS'] != "on") {
echo "This is not HTTPS";
}else{
echo "This is HTTPS";
}
9) Generate CSV file from a PHP array——在PHP数组中生成.csv 文件
复制代码 代码如下: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 $contents;
}
10.查找Longitudes与Latitudes之间的距离
复制代码 代码如下:function getDistanceBetweenPointsNew($latitude1, $longitude1, $latitude2, $longitude2) {
$theta = $longitude1 - $longitude2;
$miles = (sin(deg2rad($latitude1)) * sin(deg2rad($latitude2))) + (cos(deg2rad($latitude1)) * cos(deg2rad($latitude2)) * cos(deg2rad($theta)));
$miles = acos($miles);
$miles = rad2deg($miles);
$miles = $miles * 60 * 1.1515;
$feet = $miles * 5280;
$yards = $feet / 3;
$kilometers = $miles * 1.609344;
$meters = $kilometers * 1000;
return compact('miles','feet','yards','kilometers','meters');
}
$point1 = array('lat' => 40.770623, 'long' => -73.964367);
$point2 = array('lat' => 40.758224, 'long' => -73.917404);
$distance = getDistanceBetweenPointsNew($point1['lat'], $point1['long'], $point2['lat'], $point2['long']);
foreach ($distance as $unit => $value) {
echo $unit.': '.number_format($value,4).'
';
}
The example returns the following:
复制代码 代码如下:miles: 2.6025
feet: 13,741.4350
yards: 4,580.4783
kilometers: 4.1884
meters: 4,188.3894
11.完善cURL功能
复制代码 代码如下:function xcurl($url,$ref=null,$post=array(),$ua="Mozilla/5.0 (X11; Linux x86_64; rv:2.2a1pre) Gecko/20110324 Firefox/4.2a1pre",$print=false) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
if(!empty($ref)) {
curl_setopt($ch, CURLOPT_REFERER, $ref);
}
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
if(!empty($ua)) {
curl_setopt($ch, CURLOPT_USERAGENT, $ua);
}
if(count($post) > 0){
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
}
$output = curl_exec($ch);
curl_close($ch);
if($print) {
print($output);
} else {
return $output;
}
}
12.清理用户输入
复制代码 代码如下:<?php
function cleanInput($input) {
$search = array(
'@<script[^>]*?>.*?</script>@si', // Strip out javascript
'@<[\/\!]*?[^<>]*?>@si', // Strip out HTML tags
'@<style[^>]*?>.*?</style>@siU', // Strip style tags properly
'@<![\s\S]*?--[ \t\n\r]*>@' // Strip multi-line comments
);
$output = preg_replace($search, '', $input);
return $output;
}
?>
<?php
function sanitize($input) {
if (is_array($input)) {
foreach($input as $var=>$val) {
$output[$var] = sanitize($val);
}
}
else {
if (get_magic_quotes_gpc()) {
$input = stripslashes($input);
}
$input = cleanInput($input);
$output = mysql_real_escape_string($input);
}
return $output;
}
?>
13.通过IP（城市、国家）检测地理位置
复制代码 代码如下:function detect_city($ip) {
$default = 'Hollywood, CA';
if (!is_string($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 $default; } }
14.设置密码强度
复制代码 代码如下:
function password_strength($string){
$h = 0;
$size = strlen($string);
foreach(count_chars($string, 1) as $v){
$p = $v / $size;
$h -= $p * log($p) / log(2);
}
$strength = ($h / 4) * 100;
if($strength > 100){
$strength = 100;
}
return $strength;
}
var_dump(password_strength("Correct Horse Battery Staple"));
echo "<br>";
var_dump(password_strength("Super Monkey Ball"));
echo "<br>";
var_dump(password_strength("Tr0ub4dor&3"));
echo "<br>";
var_dump(password_strength("abc123"));
echo "<br>";
var_dump(password_strength("sweet"));
15.检测浏览器语言，只提供可用的$availableLanguages作为数组(‘en', ‘de', ‘es')
复制代码 代码如下:function get_client_language($availableLanguages, $default='en'){
if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
$langs=explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE']);
//start going through each one
foreach ($langs as $value){
$choice=substr($value,0,2);
if(in_array($choice, $availableLanguages)){
return $choice;
}
}
}
return $default;
}
16.创建数据URL
复制代码 代码如下:function data_uri($file, $mime) {
$contents=file_get_contents($file);
$base64=base64_encode($contents);
echo "data:$mime;base64,$base64";
}
17.创建更加友好的页面标题SEO URL
输入示例：$title = “This foo's bar is rockin' cool!”; echo makeseoname($title); //RETURNS: //this-foos-bar-is-rockin-cool
复制代码 代码如下:function make_seo_name($title) {
return preg_replace('/[^a-z0-9_-]/i', '', strtolower(str_replace(' ', '-', trim($title))));
}
18.终极加密功能
复制代码 代码如下:// f(ucking) u(ncrackable) e(ncryption) function by BlackHatDBL (www.netforme.net)
function fue($hash,$times) {
// Execute the encryption(s) as many times as the user wants
for($i=$times;$i>0;$i--) {
// Encode with base64...
$hash=base64_encode($hash);
// and md5...
$hash=md5($hash);
// sha1...
$hash=sha1($hash);
// sha256... (one more)
$hash=hash("sha256", $hash);
// sha512
$hash=hash("sha512", $hash);
}
// Finaly, when done, return the value
return $hash;
}
19a.Tweeter Feed Runner——使用任意twitter名，可在任意页面上加载用户资源。
复制代码 代码如下:
public function loadTimeline($user, $max = 20){
$this->twitURL .= 'statuses/user_timeline.xml?screen_name='.$user.'&count='.$max;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $this->twitURL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$this->xml = curl_exec($ch);
return $this;
}
public function getTweets(){
$this->twitterArr = $this->getTimelineArray();
$tweets = array();
foreach($this->twitterArr->status as $status){
$tweets[$status->created_at->__toString()] = $status->text->__toString();
}
return $tweets;
}
public function getTimelineArray(){
return simplexml_load_string($this->xml);
}
public function formatTweet($tweet){
$tweet = preg_replace("/(http(.+?))( |$)/","$1$3", $tweet);
$tweet = preg_replace("/#(.+?)(\h|\W|$)/", "#$1$2", $tweet);
$tweet = preg_replace("/@(.+?)(\h|\W|$)/", "@$1$2", $tweet);
return $tweet;
}
19b. Tweeter Feed Runner——用于在主题中创建文件，比如：example.php
复制代码 代码如下:
loadTimeline("phpsnips")->getTweets();
foreach($feed as $time => $message){
echo "<div class='tweet'>".$twitter->formatTweet($message)."<br />At: ".$time."</div>";
}

稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！
昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
