Add http:// prefix to URL when missing

Question

Hello I have a very simple code

<a href="'.$aProfileInfo['Website'].'" target="_self">     <div class="callButton">Website</div> </a> 

The problem is that if the user does not enter http:// the link will then point to my website and not to the external website as it should.

How do I check in PHP if the user has not entered http:// and automatically add it when it is not there?

I think you'd better use the built in function parse_url() which returns an associative array with its components

something like this will work for you:

 if  ( $ret = parse_url($url) ) {        if ( !isset($ret["scheme"]) )        {        $url = "http://{$url}";        } }
