RE: [PHP] dirty words

To be case insensitive using PHP < 5 I guess you would have to preg_split() then iterate through each array element converting to lowercase before doing the comparison, something like below, or include all case combos in your $badwrds array, ie poo, Poo, POO etc. $string = file_get_contents($url); $wordArray = preg_split(your_regex, $string); foreach ($wordArray as $word) { if (in_array(strtolower($word),$badwords)) { $string = str_replace($word, '***', $string); } } Or something along those lines. It's been a long day... Someone here will surely post a much simpler solution :) Graham > -----Original Message----- > From: Kevin Waterson [mailto:kevin@oceania.net] > Sent: 16 October 2004 16:12 > To: php-general@lists.php.net > Subject: Re: [PHP] dirty words > > > This one time, at band camp, Mag <genphp@yahoo.com> wrote: > > > Hi, > > I am useing file_get_contents on a remote page then > > using stristr() to make sure there are no "bad words" > > and its a family site. > > Right now I am checking for just 3 bad words which > > means 3 stristr() function calls, but if the bad words > > increase then that would mean more calls.... > > $badwords = array('poo', 'bum', 'perl'); > > $goodString = str_replace($badwords, '***', file_get_contents($url); > > echo $goodString; > > If you are using php5 you can use str_ireplace() for a case insensitive > search > > Kevin > --------- > "Democracy is two wolves and a lamb voting on what to have for lunch. > Liberty is a well-armed lamb contesting the vote." > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > >
