Sensoring......

Hey people....

I am making a maeesageboard for an online community. A rule that we have is there is to be no swearing. So, I was wondering, is there a way that every swear word can be replaced with #@*%$ etc?

Please help,

You will probably have to do a bunch of ereg_replace on the text in question. I would put all of the swear words I know into an array and do ereg_replace against that.

Ex. (Not functional)

// $string_in_question is the user input string

$swear_words = array ("swear1","swear2");

for ($i=0; $i < count($swear_words); $i++){
ereg_replace ($swear_words[$i], "#@*%", $string_in_question);
}

Good Luck

ereg_replace ($swear_words[$i], "#@*%", $string_in_question);

.. should be ..

$string_in_question = ereg_replace ($swear_words[$i], "#@*%", $string_in_question);

Umm, it doesn't work. The $string_in_question get's echo'd 3 times if I say echo $string_in_question within the loop. And outside the loop it says the $string_in_questions once without filteration.

might try eregi_replace .. the "i" means case insensitive.

I tried this code myself and it works the eregi is needed. (Thanks Ken)

<?php

/**
testereg.php - Text filter
*/

$string_in_question = "Get your SWEAR1 hands off my swear2 girlfriend";

$swear_words = array ("swear1","swear2");

echo "Before: $string_in_question<br>";
for ($i=0; $i < count($swear_words); $i++){
$string_in_question = eregi_replace ($swear_words[$i], "#@*%", $string_in_question);
echo "Iteration $i: $string_in_question<br>";
}

echo "After: $string_in_question<br>";
?>

Thank you, it's works now. Thanx again for your help.

Hi,
I just read all the above answers and they're all pretty good but they dont stop someone typing sshit! or fuk unless you specify everything possible in an array.
I had a problem with this and ended up creating a function to 'dissallow' bad words including 'z's instead of 's's etc. It was made to stop someone entering a name that contained swearing so it wont be perfect for your needs. You might want to check it out and work the idea into the above answers.
It's posted on the 'Code Library' (this site) under algorithms. bad_word() function.

Can I ask for my information, why can't I just put this.......

$Array = array("swear1", "swear2");

$result = eregi_replace($Array, "#@£$%", $Message);

Why do you put.....

for ($i=0; $i < count($Array); $i++) {

$Message = eregi_replace ($Array[$i], "#@*%&", $Message); 

}

What is the difference?

Thank you,

This is really a tough prblem to tackle because all of the variants and ways you can type a word.

Lets see if phpbuilder filters this stuff out...
I am swearing now > @!#$

Here is a workaround
I am swearing now > a_s_s_h_o_l_e
See what I mean

One way to help battle bad words is to assign a moderator to the forum and have them explicitly moderate each and every post. For a big site with tons of posts this isn't very practical.

Good Luck.

Read the manual on how it uses arrays as arguments. There may not be any and it may be faster.

Another problem you will run across in your censoring of words is that if you don't do your eregi to check ONLY from beginning of string to end of string you will end up censoring common words.

For example :
Censoring the word "semen" might make -
Advertisement into Adverti@#$%ment.

Or glass could end up gl@#$%

So make sure you are checking for only full strings. (use ^ and $).

Also, using str_replace, it searches thru the whole string and ends up with the same replacement problems, thus glass becomes gl###, as you say.

But I don't see those ^ and $ switches mentioned in the PHP lit for ereg().

Could you elaborate, please, on how these are included in the function call?

Anon

Sure no problem.

In a regular expression (ereg or eregi <- the i is the same as ereg but case iNsEnSiTiVe) the carat (⁾ denotes that the expression should start at the beginning of the string to be searched and the dollar sign ($) means to search to the end of the string.

For example
(code is not tested and off the cuff)
$string = glass;
ereg("ass", $string)
would produce gl### because it is searching the whole $string where as
ereg("^ass$" $string)
would allow glass to pass through untouched because the string doesn't START with "ass" as the ereg ^ specifies.

I hope this helps but I realize I am not a teacher and probably might need to explain my half assed instruction further. Feel free to ask if it is still muddy.

exact code I use it all the time:

#example bad input
$input = "@!#$ damn ass hello";

#how sensoring should look
$rep="!@$#*";

$input=ereg_replace('ass',$rep,$input);
$input=ereg_replace('@!#$',$rep,$input);
$input=ereg_replace('damn',$rep,$input);

when $input is displayed, it would look like this:

!@$# !@$# !@$#* hello

Of course you could change it so that
$rep="";

And then it would look like this when you dipslay it:

hello

I hope that helps.

DANG! Look at the previous post! It looks like my little sensoring tool is almost exactly like this forums!
