If you expect it at the beginning of the string you can do something like this:
$string = 'http://www.google.com';
$string = (substr(ltrim($string), 0, 7) != 'http://' ? 'http://' : '') . $string;

so if the user enters www.blah.com it will end up http://www.blah.com?

To understand Inigoesdr's code you'll want to study these web pages:
Ternary operators (http://us2.php.net/manual/en/language.operators.comparison.php) (scroll down til you get to the paragraph on ternary operators)
I don't think you should use any code that you don't understand.

what you do you think is the best way to store links in a database I tried htmlentinty(), special chars. this is how my form processor is handling it
$blog1_url = mysql_real_escape_string(htmlentities($_POST['blog1_url']));
