查找网站列表，返回安全错误PHP

Question

I'd like to write a php script that will check a list of URLs in an array and return whether that URL resolves successfully or whether there is a security error.

Specifically I'm trying to detect the "this page is not secure" message that appears when you visit a site using https:// that doesn't have a valid SSL certificate.

So I figured I'd use a foreach loop to cycle through the array testing each URL. then echo either success, or error depending on whether it encounters a security error.

    $urls = array(
    'https://one.com',
    'https://two.com',
    'https://three.com'
    );

    foreach( $urls as $key => $value){
        //look up current domain name. if it resolves echo "success" 
        //else if an SSL error is encountered echo "error"
    }

Sorry I haven't gotten very far. Not sure where to start. Does anyone know a simple way to do this?

thanks.
