Searching A String

[Andy252]

I want to add a URL banning feature to my website

Initially I was just going to ban the full url as entered by the users, however, in some cases the url may change by using ?page=Bla, and therefore would not be identified as a banned url. Instead I need to be able to search the url entered for entries in a mysql database. What  function do I need to be using the search the string for banned urls?

[code=php:0]
<?PHP
$banned_url = array('umm', 'Bla', 'opr', 'ah');
if(in_array($_GET['page'], $banner_url)) {
echo "Invalid Access.";exit;
}
?>
[/code]

Is that what you mean?

URLs in user content (like posts)? Or URLs that link to your site?

OK, Actually I need two seperate script but I don't want to jump the gun....


Users submit URLs via a form on my site, which is then put into MySQL.

The first problem is not all the URLs are following the rules are therefore I want to add a banning features. I can't simply ban the domain because for the likes of tripod / geocities it will ban everyone. I also can't ban the full url because urls because users will bypass the banning feature by removing the "www." or adding  "?page=1".

Instead I need to be able to ban *tripod.com/directory*, or something like *domain.com/~user/*

Once I have this in place I need to add a feature that will test the URLs are correct because after looking at my database there are a lot of entries which look like this... http://kljfhigufwuergfosuhailu, or http://0000.

Thanks for your help guy !

Use regular expressions. Can you provide more examples?
