[PHP] 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);}

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)
{
.
}

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...
}

What I use:
function check_bad_content($string)
{
// Stuff that spammers post with:
$bad_strings = array('www.','/url]','ttp://','ttps://') ;
foreach( $bad_strings as $bad_string )
{
if ( ereg( $bad_string, $string ) ) return false ;
}
return true;
} // E-O- function check_bad_content
I permit _*NO*_ URL's on my message board. I guess you could just as
easily count them in the function above -- versus setting TRUE/FALSE.
