Re: link counting

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 -- itoctopus - http://www.itoctopus.com "Sebe" <sebastian@dslr.net> wrote in message news:461644A0.9030009@dslr.net... > i thought of an idea of counting the number of links to reduce comment spam. > > unfortunately my methods is not reliable, i haven't tested it yet > though.. anyone have maybe a better solution using some regexp? > > $links = array('http://', > 'https://', 'www.'); > > $total_links = 0; > foreach($links as $link) > { > $total_links = substr_count($string, $link); > } > > if($total_links > X) > { > ..... > }
