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. Tijnema

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...

}

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) {

    .....

}
