OK what's a better way to do this?

I currently have a script where I store the array right there in the file like so..

$banned_url = array();
$banned_url[] = 'http://www.badsite.com';
$banned_url[] = 'http://www.badsite.com/';
$banned_url[] = 'http://badsite.com';
$banned_url[] = 'http://www.someothersite.pl/';
$banned_url[] = 'http://someothersite.pl';

I use that array to block bad URLs from being posted to my text file like this..

if (in_array("$url", $banned_url)) { echo "<br><br><font color=red><b>Banned Link<br>Nice try clown!<br><br></b></font>"; } else {


1) I'd like a better way to add banned URLs. I've made a script to let the admin enter a URL and add it to a text file one line at a time like $banned_url[] = '$url';. but is there a simpler way to use the array or even do it without an array?

2) You'll also notice I have to input every possible way you can write the URL. Is there a way to block the entire domain? I know there is I just don't know how.


Any help will be mucho appreciated.

What I would think of would be to keep the URLs in an array and make a loop which would run every entry in the array and check it against the URL to see if it matches with preg_match and then run something with it to make it hide the banned site if it is actually a banned site or show the URL if it isn't.

Preg_match: http://www.php.net/preg_match

Sounds good but the problem with that is that I want something to alert the poster right off the bat that their link wasn't posted. Once I get this figured out I'll probably include a function that emails the script owner of the failed link attempt.

Wait i don't exactally get what you mean....
you want it so that it alters the link in the post made if it includes a badurl?

EDIT:

PHP Code:

<?

$post = 'check it out lala.ca hmm weird name eh? how about sucks.net? or [url]http://lala.ca[/url] or [url]http://sucks.net[/url] but SUCKS.NET doesn't work..';



$bannedurl[] = '/lala.ca/';

$bannedurl[] = '/sucks.net/';



$goodurl = 'gfx-pro.ath.cx';



foreach($bannedurl as $url) {

 $post = preg_replace($url, $goodurl, $post);



}

echo $post;

?>

No,

I just want it to recognize the bad url and not post it to the text file AND display a message.

Edit.. ill get back to you in a sec( why can't i delete a post?!!? enable that )

first, you don't really need to have this line:
$banned_url = array();

just $banned_url[] is fine and will inetilize the array ..

and there is no need to use regexp function here !! it's only string replacement !!
so just use str_replace();
if you want to alert use a small IF statment !!

PHP Code:

$banned_url[] = 'http://www.badsite.com/';

$banned_url[] = 'http://badsite.com';

$banned_url[] = 'http://www.someothersite.pl/';

$banned_url[] = 'http://someothersite.pl';



//the text message ..

$text = trim(addslashes($_POST['text']));



foreach ($banned_url as $nogood) {

  if (stristr($text, $nogood)) {

    $alert[] = $nogood;

    $text = str_replace($nogood, '<i>Bad URL!</i>', $text);

  }

}



if (count($alert) > 0) {

  foreach($alert as $promp) {

      $error .= 'You tried to use this URL '.$promp.' but it is a bad URL !';

  }

}



//echo $error where ever you want .. 

this will replace all bad URLs (if found) with an Italic "Bad URL" !!
then if the array alert has any elemnts, then we bump it into $error var ..

Hey thanks alot.

What about banning multiple entire domains instead of having to add a URL for every minor change like http://mydomain.com or http://mydomain.com/porn and http://mydomain.com/ with the traling slash etc.

Thanks,

I wont say anything until you try the code I wrote and try all these URLs and see how it will work
