$compressed = gzcompress($string);

9. 使用PHP做Whois检查

function whois_query($domain) {

// fix the domain name:

$domain = strtolower(trim($domain));

$domain = preg_replace('/^http:///i', '', $domain);

$domain = preg_replace('/^/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 pedia/wiki/Whois

//

$servers = array(

"biz" => "whois.neulevel",
