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。

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:
    //
    // 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, $domain."rn");
        while(!feof($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。

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。

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 
*/
