使用http://upfront将网站的URL设置为字符串格式 [英] Format a website´s URL as a string with http:// upfront

问题描述

我有一个评论系统，该系统允许自动链接url.我正在使用cakephp，但解决方案更多是PHP.这是正在发生的事情.

I have a comment system that allows auto linking of url. I am using cakephp but the solution is more just PHP. here is what is happening.

如果用户使用http://或https://输入完全限定的url，则一切正常. 但是如果他们输入www.scoobydoobydoo.com，它将变成http://cool-domain.com/www.scoobydoobydoo.com.基本上，cakephp知道http | https是一个外部URL，因此它不能与http | https一起使用.

if the user enters fully qualified url with http:// or https:// everything is fine. but if they enter www.scoobydoobydoo.com it turns into http://cool-domain.com/www.scoobydoobydoo.com. basically cakephp understands that http|https is an external url so it works with http|https not otherwise.

我的想法是对URL进行某种形式的str操作，并使其插入http(如果不存在的话).不幸的是，我所做的一切只会使情况变得更糟.我是菜鸟:)任何帮助/指针都表示赞赏.

My idea was to do some kind of str stuff on the url and get it to insert the http if not present. unfortunately whatever i try only makes it worse. I am noob :) any help / pointer is appreciated.

谢谢
