PHP cURL does not work when calling multiple URLs?

I am trying to take a list of URL's from a textbox, it has 1 URL per line and each URL does a redirect, I am trying to get the URL that it redirects to.

When I run this code below on a single URL, it returns the redirected URL which is what I want...

function getRedirect($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, true); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
    $result = curl_exec($ch);
    $info = curl_getinfo($ch); //Some information on the fetch
    curl_close($ch);

    echo '<pre>';
    print_r($info);
    echo '</pre>';

}

$url = 'http://www.domain.com/go?a:aHR0cDovL2xldGl0Yml0Lm5ldC9kb3d';
getRedirect($url);

Now my problem is when I try to run it on multiple URL's with this code...

if(isset($_POST['urls'])){
    $rawUrls = explode("\n", $_POST['urls']);

    foreach ($rawUrls as $url) {
        getRedirect($url);
    }
}

When I run it on my list of URL's instead of giving me the redirected URL like my first example does correctly, it instead gives me the URL that I passed into cURL.

Can someone help me figure out why or how to fix this please?

It's already covered in the question comments but it seems the problem would be extra spacing at the end of the url.

Calling getRedirect(trim($url)) would fix it.

The space at the end is most likely turned into a querystring space (aka %20) and changes the value of query string parameters
