19个超实用的PHP代码片段

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('https://www.jb51.net/', $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="https://de.wikipedia.org/wiki/Whois"></a> 
    // 
    $servers = array( 
        "biz" => "whois.neulevel.biz",

    ); 

    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; 
}
