Need a Simple URL Converter...

[itsureboy]

I need some simple code that would take a URL and convert it to its utmost proper form which would be for example,

 

http://www.site.com

 

So if a user submits the URL short without the http://, or www.  the code would add it accordingly.

 

Any help. 

 

Thanks ahead.

Well, you could do

if (strncmp($url, 'http://', 7) != 0) {
    $url = 'http://' . $url;
}

 

You're wrong about the www stuff. The domain name www.example.com doesn't need to point to the same place as example.com.

It's possible you could use a redirect like so, of course putting what you would like in the url.

 

<?php

ob_start();

header("Location: http://en.wikipedia.org");

ob_flush();

?>

How would redirecting the user take care of normalizing the string?

or just, if you want.

$url = str_replace('http://', $url);
$url = 'http://' . $url;

 

But daniel's way sounds better.
