OK, so this is a simple word filter I made for use in any application like
<![CDATA[
plug-n-play. Quite simple and easy to use.
So here goes. Following this is an example on how to use it.
Filter.php:
<?php
This function does all the work. If $replace is 1 it will replace all bad words with the wildcard replacements. If $replace is 0 it will not replace anything. In either case, it will return 1 if it found bad words or 0 otherwise.Be sure to fill the $bads array with the bad words you want filtered.
***************************************************************/
function Filter(&$text, $replace)
{
//fill this array with the bad words you want to filter and their replacements
$bads = array (
array("Fool","F**l"),
array("crap","c***")
);
if($replace==1)
{
//we are replacing
$remember = $text;
for($i=0;$i<sizeof($bads);$i++)
{
//go through each bad word
$text = eregi_replace($bads[$i][0],$bads[$i][1],$text); //replace it
}
if($remember!=$text) return 1; //if there are any changes, return 1
} else {
//we are just checking
for($i=0;$i<sizeof($bads);$i++)
{
//go through each bad word
if(eregi($bads[$i][0],$text)) return 1; //if we find any, return 1
}
}
}
?>
Example1.php
<?php
include('Filter.php');
// This will replace all bad words with their replacements.$any is 1 if it found any
$result = Filter($wordsToFilter,1);
//this will not repace any bad words but instead will only search for them. $any is 1 if it found any
$result = Filter($wordsToFilter,0);
?>
