Checking if Image exist using url returns false in some ocasions

Question

I'm wondering what would make this code falsely fail. It returns false result when passing certain Image URLs. I don't have control of what the URL is, but I can encode it somehow to make this work?

I assume the problem lays with the space located in the Image URL. How to avoid this?

function checkRemoteFile($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    // don't download content
    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_setopt($ch, CURLOPT_FAILONERROR, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    return (curl_exec($ch)!==FALSE);
}

if you get false back, then something failed, and you should be checking `curl_error($ch)` to find out why. — Marc B, Oct 08 '14 at 19:15

Use $url = str_replace(' ','%20',$url); to urlencode the spaces.
