Swear Filter Question (class)

[Canman2005]

Hi all

 

I've done a function to replace swear words.

 

The problem I have is if someone types "class" then it returns "cl***" thinking the last part of "class" (ie: "ass") is a swear word. I had to therefore remove it.

 

Is there a separate replace function I can run just to check for the single word "ass" and then replace it?

 

Thanks in advance

use regular expression

You can break the string into an array of words, and match each word (case insensitive) to the list of profanities.

long process what if you have say: teng, astig , ako and you have to find them so the process will need loop and if condition right?

Yes it will be a longer code vs the user of regex, but the it will run faster.  I see nothing wrong with writing code using loop and condition.

i believe with that process of yours regex will run faster

[hvle]

why don

i believe with that process of yours regex will run faster

 

don't believe, you should implement a code and prove regex is faster.

im not going to argue do it your way even if takes your coding messy and long

 

ok post your code and help this tread starter with your way

<?php
$data = "hello you bad1, how the bad2";
$Bad= array("bad1", "bad2", "bad3");
$Replace   = array("***", "***", "***");
$data = str_ireplace($Bad, $Replace, $data);
?>

 

If you want advanced (more flexable) filtering then RegEx would be better, but a little slower

RegEx would probably be my choice, as you can catch things which would noramlly require a few lines use any other method

simple RegEx Example

<?php
$data = 'hello you bad1, how the bad2';
$patterns[] = '/bad1/i';
$replacements[] = '***';

$patterns[] = '/bad2/i';
$replacements[] = '***';

$patterns[] = '/f??k/i';
$replacements[] = '***';

$data =  preg_replace($patterns, $replacements, $data);
?> 

 

You can break the string into an array of words, and match each word (case insensitive) to the list of profanities.

That will be more complex and much slower..

this is no simple regex, and str_replace.  need something that replace whole word, not only patterns.

Yeah see examples posted!!.. its not hard.. infact most would say its kinda simple!
