利用php獲取網站備案信息的方法

php代碼如下：

<?php 
function miibeian($domain) { 
$domain = base64_encode ( $domain ); 
$opts = array ( 
'http' => array ( 
'method' => "GET", 
'timeout' => 5 
) 
); 
$context = stream_context_create ( $opts ); 
$url = 'http://webid.#/complaininfo.php?domain=' . $domain; 
$html = file_get_contents ( $url, false, $context ); 
if (strpos ( $html, '未查詢到網站信息' )) { 
return false; 
} 
$flag = '<ul>'; 
$start = strpos ( $html, $flag ) + strlen ( $flag ); 
$info = substr ( $html, $start, strpos ( $html, '</ul>' ) - $start ); 

$info = str_replace ( ' ', '', $info ); 
$info = str_replace ( '<li><strong>網站名稱:</strong>', '', $info ); 
$info = str_replace ( '<li><strong>網站首頁地址:</strong>', ' ', $info ); 
$info = str_replace ( '<li><strong>主辦單位名稱:</strong>', ' ', $info ); 
$info = str_replace ( '<li><strong>主辦單位性質:</strong>', ' ', $info ); 
$info = str_replace ( '<li><strong>審核時間:</strong>', ' ', $info ); 
$info = str_replace ( '<li><strong>網站備案/許可證號:</strong>', ' ', $info ); 
$info = str_replace ( "\r\n", '', $info ); 
$info = str_replace ( '</li>', '', $info ); 
$info = trim ( $info ); 
$temp = explode ( ' ', $info ); 
return $temp; 
} 
// http://webid.#/complaininfo.php?domain=c3lzeXVuLmNvbQ== 
$result = miibeian ( 'yisu.com' ); 
print_r ( $result );
