text to link, problem with link that has not https

Users can add texts. This texts can have links.

I'd like do add click to it.

The problem is, some links works like:

http://www.example.com

links that has no http will not work and will become:

http://mywebsite.com/www.example.com

any ideas how to solve it?

function toLink($titulo){
    $url = '~(?:(https?)://([^\s<]+)|(www\.[^\s<]+?\.[^\s<]+))(?<![\.,:])~i'; 
    $titulo = preg_replace($url, '<a href="$0" target="_blank" title="$0">$0</a>', $titulo);
    return $titulo;
}

Use preg_replace_callback instead and you can interrogate the match to see if you need to add the protocol.

function toLink($titulo) {
    $url = '~(?:(https?)://([^\s<]+)|(www\.[^\s<]+?\.[^\s<]+))(?<![\.,:])~i'; 
    $titulo = preg_replace_callback($url, function($matches) {
        $url = $matches[0];
        if (!preg_match('/^https?:\/\//', $url)) $url = 'http://'.$matches[0];
        '<a href="'.$url.'" target="_blank" title="'.$url.'">'.$url.'</a>';
    }, $titulo);
    return $titulo;
}
