Getting multiple http response codes using cURL? - php

Question

Please take a look at this sample code:
function http_response($url)
{
$ch = curl_init();
curl_setopt($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:
Can I get rid of some setopt() lines here and still getting httpCode?
What about if I want to check multiple urls at the same time? Can I modify the code to do that?
Can I do the same functionality in a simpler way using libraries different than cURL?
Thanks :)

Answer 1

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();
