Re: [PHP] Replacing with f*ck and f*cking
My question is this, for just two words its fine to use the above, but a pal tells me that if using a lot of words (eg: 15) and the $comment is big then it can take quite some time and be a bit of a processing strain as well because php first checks the first word from the good list against all the 15 words in the bad list against the comment then moves to the second word etc. You should do the filtering on save, not on display, this way the processing time will drop by order of few magnitudes in comparison. Always save the original post content as well, in case you want to tweak the filter and reprocess the messages.

Regards, Stan Vassilev What you really need to watch out for is words which you're going to censor which might be part of other names. Sex is an obvious one, as it appeared in the borough name of my old address: Middlesex. Instead of using str_replace, what about using preg_replace, which gives you a bit more control over the words that you are replacing, for example, only words on their own, etc. This will also let you get around deliberate mis-spellings of a profanity, such as 'fcuk', by using an expression like /f[uc]k/iw Obviously, this list could get pretty comprehensive, so like Andrew said, maybe you should look to see how some of the open source projects do it.

Ash www.ashleysheridan.co.uk The way Drupal handles such filtering is simple caching. As a policy we never filter general content on save, because we may want to change the filter format later and destroying user-submitted data is *not cool*. However, we do apply a number of possible filters on display (add line breaks, convert URLs to clickable, do bad word filtering, or any number of other things) and then just cache the result. The cache lookup (based on a hash of the string being filtered and the ID of the filter set to apply) is far faster than reapplying the filters every time. We've found this mechanism to scale very well. -- Larry Garfield [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Replacing with f*ck and f*cking
Hey! I'm just trying to replace some of the more bad words with their slightly censored counterparts like so $bad_words = array(/*Well you know the words so am not going to write them here*/); $bad_words_replacements = array(f*ck, f*cking); $comment = str_replace($bad_words,$bad_words_replacements, $comment); My question is this, for just two words its fine to use the above, but a pal tells me that if using a lot of words (eg: 15) and the $comment is big then it can take quite some time and be a bit of a processing strain as well because php first checks the first word from the good list against all the 15 words in the bad list against the comment then moves to the second word etc. Is this really bad processing wise and would you recommend any other way of doing this? The other question i have is, wont f*ck catch f*cking as well? so should i delete the longer f*cking? I'm not really trying to stop people swearing... just trying to make it not jump out so much, this was the poster is happy coz i have not censored him to bits and the reader should be a bit happy coz its a bit decent.

Re: [PHP] Replacing with f*ck and f*cking
Maybe you should look at the source code of an open source project that can already do this such as phpBB. I'm not exactly sure where to find it in the phpBB code though.
