[RESOLVED] Word Censor

[mpasternak]

Hey all,

I have just created a simple "Whiteboard" for an internal page where users can post messages to each other and assign it to specific jobs. It works great.

however, This maybe a simple task. But since this is a professional page in a corporation, I need to sensor it. The system is simple. The page is a simple form with a Subject, and Text field. Everything else thats needed is automatically filled out by the system (User and session).

What Im' basically looking for is a way to scan through the subject / text feild automatically checking every word against a dictionary. if it finds a match, replace that word with ***** (strlen to dtermine how many).

help is greatly appreciated

ps: I want to create it as a function in a header file so i can call it from multiple pages.

$text = wordcheck($textinput);

This should start you off...

<?php

$words = "hello welcome to php builder products.  we sell php builders, etc, very good time.<br>\n";
$words.= "We build PHP builders, building builders is building php builders builder way.<br>\n";
$words.= "building tobuild sobuildso, and stuff...<br>\n";

function badwords($str) {
	$badwords = array("sell","etc","time", "build");

foreach ($badwords as $key=>$word) {
	$words = ereg_replace($word,"[****]",$str);
}
return $words;
}
//echo $words;
echo "Origional:<br> $words<br><br>\nCencored:<br>";
echo badwords($words);
?>

Good Luck

A more optimized solution might be...

function badwords($str) { 
    $badwords = array("sell","etc","time", "build"); 

return str_replace($badwords, '[****]', $str); 
} 

Then again, neither of our functions will block "Sell" or "SEll", etc. If you have PHP5, you can use the [man]str_ireplace/man function instead.
