PHP - get_headersとSSL

Question

でのエラーはこれが

$url = 'http://www.wikipedia.com'; // URL WITH HTTP 
$hurl = str_replace("http", "https", $url); // URL WITH HTTPS 

$urlheads = get_headers($url, 1); 
$surlheads = get_headers($hurl, 1);  
$urlx = false; 
$surlx = false; 

foreach ($urlheads as $name => $value) 
{ 
    if ($name === 'Location') 
    { 
     $urlx=$value; 
    } 
    else{ 

    } 
} 
print_r($urlx); 

私のコードであり、これは私が取得していますエラーです：

Warning: get_headers(): Peer certificate CN=`*.wikipedia.org' did not match expected CN=`www.wikipedia.com' in.... 

Warning: get_headers(): Failed to enable crypto in.... 

Warning: get_headers(https://www.wikipedia.com): failed to open stream:  operation failed in ..... 
Array ([0] => http://www.wikipedia.org/ [1] => https://www.wikipedia.org/) 

なぜこれが起こっていると何からヘッダを取得するための適切な方法でありますhttpsページでエラーなし（カールなし）。また、他のhttpsサイトを試してもOKです。

Answer 1

問題は、サーバ証明書がワイルドカード*として表示されるため、すべてのサブドメインで同じ証明書を使用できるようになっていますが、ワイルドカード*はSSL検証中に文字通り使用され、失敗につながります。この問題を回避するには、stream_context_set_default()を使用してSSL検証をfalseと設定します。

stream_context_set_default([ 
    'ssl' => [ 
     'verify_peer' => false, 
     'verify_peer_name' => false, 
    ], 
]); 

$url = 'https://www.wikipedia.com'; // URL WITH HTTPS 

$headers = get_headers($url, 1); 

var_dump($headers); 

それが働いて出力
