Use the function is_url (note that I haven't written it) instead to
check if
the link is a URL.
Not only your method may count some links twice, but it will count wrong
URLs also.
<a href='www.externaldomainnamehere.com'>External</a> is not a URL
that will
take someone externally.
Below is the function is_url
function is_url($url) { return
preg_match('#^http\\:\\/\\/[a-z0-9\-]+\.([a-z0-9\-]+\.)?[a-z]+#i',
$url);}
taken from this link:
http://plurged.com/code.php?id=26
Hmm, it does only take http links, not https,ftp, etc.

I came up with this, not sure if there is a better/faster way but it
works for me.
it's case insensitive so you don't have to use strtolower()
preg_match_all('%http://|https://|ftp://%i', $string, $links);
if(count($links[0]) > 2)
{
// error...
}
