Logic for Adding To A URL

[dfalzoi]

I'm trying to get code to work along the following logic (or something similar if this logic isn't PHP-friendly).

 

If a user inputs a URL with the http, I want the url left alone.

If the user inputs the URL starting with www, I want http:// added to the beginning.

If the user does anything else (in other words uses a relative link), I want the beginning of my url to be added on (because then I later check for it to open the website in a new window or not).

 

if (strpos($url, "http") == 0) { $url = $url; }
else if (strpos($url, "www") == 0) { $url = "http://".$url; }
else { $url = "http://www.mywebsite.com/".$url; };

 

Any suggestions?

You didn't state the problem, but if http is NOT found then strpos() will return false which is == 0.  So you want to use === to check type as well.  Same with www.
