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> 
    // 
    $servers = array( 
        "biz" => "whois.neulevel.biz", 
        "com" => "whois.internic.net", 
        "us" => "whois.nic.us", 
        "coop" => "whois.nic.coop", 
        "info" => "whois.nic.info", 
        "name" => "whois.nic.name", 
        "net" => "whois.internic.net", 
        "gov" => "whois.nic.gov", 
        "edu" => "whois.internic.net", 
        "mil" => "rs.internic.net", 
        "int" => "whois.iana.org", 
        "ac" => "whois.nic.ac", 
        "ae" => "whois.uaenic.ae", 
        "at" => "whois.ripe.net", 
        "au" => "whois.aunic.net", 
        "be" => "whois.dns.be", 
        "bg" => "whois.ripe.net", 
        "br" => "whois.registro.br", 
        "bz" => "whois.belizenic.bz", 
        "ca" => "whois.cira.ca", 
        "cc" => "whois.nic.cc", 
        "ch" => "whois.nic.ch", 
        "cl" => "whois.nic.cl", 
        "cn" => "whois.cnnic.net.cn", 
        "cz" => "whois.nic.cz", 
        "de" => "whois.nic.de", 
        "fr" => "whois.nic.fr", 
        "hu" => "whois.nic.hu", 
        "ie" => "whois.domainregistry.ie", 
        "il" => "whois.isoc.org.il", 
        "in" => "whois.ncst.ernet.in", 
        "ir" => "whois.nic.ir", 
        "mc" => "whois.ripe.net", 
        "to" => "whois.tonic.to", 
        "tv" => "whois.tv", 
        "ru" => "whois.ripn.net", 
        "org" => "whois.pir.org", 
        "aero" => "whois.information.aero", 
        "nl" => "whois.domain-registry.nl" 
    );      if (!isset($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, $domain.""); 
        while(!feof($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 "; 
/* 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 "; 
/* prints
Final: 885912 bytes
*/  echo "Peak: ".memory_get_peak_usage()." bytes "; 
/* 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) . " 
"; 

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
    "@<![sS]*?--[ ]*>@"         // 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>";
