Getting multiple http response codes using cURL?

Please take a look at this sample code:

function http_response($url开发者_高级运维)
{
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_HEADER, TRUE);
        curl_setopt($ch, CURLOPT_NOBODY, TRUE); // remove body
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        $head = curl_exec($ch);
        $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

        echo $httpCode ;
}

this code will print the httpCode of the given url. I have couple of questions:

1. Can I get rid of some setopt() lines here and still getting httpCode?
2. What about if I want to check multiple urls at the same time? Can I modify the code to do that?
3. Can I do the same functionality in a simpler way using libraries different than cURL?

Thanks :)

• You should be able to remove CURLOPT_HEADER and CURLOPT_NOBODY and still get the same result.

• You could do that like this:

  $urls = array(
      'http://google.com',
      'http://facebook.com'
  );
  
  $status = array();
  
  foreach($urls as $url){
      $status[$url] = http_response($url);
  }
  

  Try print_r($status); after this and you'll see the result.

• You could do this with file_get_contents and $http_response_header, to learn more: http://www.php.net/manual/en/reserved.variables.httpresponseheader.php I would however recommend using cURL anyway.

*2. to check multiple urls you have to use this function in a loop, in any programming language 1 response from a server = 1 connection to that server. If you want to use 1 function to get responses from multiple servers you can always pass an array to the function and do the loop inside the function

*3. you can try this way:

function get_contents() {
  file_get_contents("http://example.com");
  var_dump($http_response_header);
}


get_contents();
