censoring comments

[ohdang888]

i want to delete curse words from user submitted comments. any suggestions about how would i go about doing that???

 

I don't even know what to search for in google.

$bad_words=array("bad word1","bad word2");
foreach($bad_words as $b)
{
$text=str_replace($b,"****",$text)
}

When you run that, you'll notice that in certain situations.... like harrassment it might become harr****mess.

 

You could always just do ' word ' instead of 'word' though.....  Oh....  Then you could have problems with 'ass.' or 'ass!' for example.... hmmm....

 

 

Edit:

 

You could use regular expression word boundries I guess......

 

<?php

$str = "ass harrass.";

$bad = array('ass');

foreach($bad as $k => $word) {
$bad[$k] = '/\b' . $word . '\b/';
}

echo preg_replace($bad, '****', $str);
//**** harrass

?>

i guess that means i have a LOT of variations in my bad word part.

Why not just add a space around " ass "?

"You're an ass."

 

Haha sorry....  I love irony.

 

In that case for example, ass wouldn't be replaced.

[aximbigfan]

Good point. Hmm.....

 

Maybe changing it so to if punctuation/spaces marks surround "ass" on one or both sides?

[ohdang888]

how would i do that?

[aximbigfan]

$pad;
$pad[0] = " ";
$pad[1] = "\"";
$pad[2] = "'";
ect...

and then add $pad on each side of the bad words var in the replace function, I guess.

<?php

$str = <<<H
This is a sentence with ass in it.
This is with ass at the end ass.
'ass'
"ass"
"Ass"
!ass!
ass
harrass
ass/ass
ASS
AsS
aSS
H;

$bad = array('ass');

foreach($bad as $k => $word) {
$bad[$k] = '/\b' . $word . '\b/i';
}

echo preg_replace($bad, '****', $str);

?>

 

 

Output:

 

This is a sentence with **** in it.

This is with **** at the end ****.

'****'

"****"

"****"

!****!

****

harrass

****/****

****

****

****

 

Regular expression word boundries....
