phpからURL（https://www.reliancesmart.in/）へのカールリクエストのステータスコードは常に0です

Question

PHPでcurlを使用してURLが有効かどうかを確認しています。 これを行う他の方法はありますか？私はこのコードを使用しています

$url = 'https://www.reliancesmart.in/';  
$handle = curl_init($url); 
      curl_setopt($handle, CURLOPT_RETURNTRANSFER, TRUE); 

      curl_setopt($handle,CURLOPT_USERAGENT,' Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.75 Safari/537.36'); 

      curl_setopt($handle,CURLOPT_VERBOSE,false); 
      curl_setopt($handle,CURLOPT_TIMEOUT,10); 
      curl_setopt($handle,CURLOPT_CONNECTTIMEOUT,45); 

      curl_setopt($handle,CURLOPT_HEADER,true); 
      curl_setopt($handle,CURLOPT_NOBODY,true); 

      curl_setopt($handle,CURLOPT_RETURNTRANSFER,true); 
      curl_setopt($handle,CURLOPT_FOLLOWLOCATION,true); 
      curl_setopt($handle,CURLOPT_MAXREDIRS,5); //follow up to 10 redirections - avoids loops 


      curl_setopt($handle,CURLOPT_SSL_VERIFYHOST,0); //fix for certificate issue 
      curl_setopt($handle,CURLOPT_SSL_VERIFYPEER,0); 

      $response = curl_exec($handle); 
      $httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE); 

      curl_close($handle); 
      if($httpCode == 0 || $httpCode == 404 || $httpCode == 500) 
       //URL is working 
      else 
       //invalid url 

$httpCodeは常に0このURLのためです。 しかし、ブラウザではURLが正常に動作しています。

Answer 1

$url = 'http://www.reliancesmart.in/Offers/'; 
$headers=get_headers($url); 
$status = ($headers[0]=='HTTP/1.1 200 OK') ? 'OK' : 'NOT OK'; 

echo '<pre>', $status,PHP_EOL,print_r($headers,1), '</pre>'; 

これは、あなたがより速くする方法は、おそらく `` get_headers（$のURL）を用いることであろうHTTPステータスコード
