If you're just checking if the string has it, you can use something like:

if ( !stristr($string, "http://") )
{
   $string = "http://{$string}";
}

Pretty simple, but, doesn't really validate much.

I use this validation a lot that you are asking about.
The below does the correction the way you want it to and you do not have to prompt the user to correct.

$variable = "ronfrederick.com";

if (ereg("http://",$variable)) { $new_var = $variable; }
else { $new_var = "http://$variable"; }

echo $new_var;

the 1st reply, which does not use regular expressions ("ereg") is faster-- thought we're talking about milliseconds here, so, it may not matter. fwiw.
