What is this part of a code indicating? That all links on page will be nofollow? if(url != ''){ s+='<a href="'+url+'" title="'+url+'" rel="nofollow" target="_blank">'+name+'<\/a>'; }else if(email != ''){ s+='<a href="mailto:'+email+'" rel="nofollow">'+name+'<\/a>'; }else if(name!=''){ s+=name; }else{ s+='Anonym'; }
This is Javascript, and not PHP. And this part seems to be creating links (yes, with nofollow), but to tell exactly what it does, you'd have to post the entire code.
