"eregi" help

[Anon]

Hi.
I'm just looking for a way to find out, if a text contains some special words.
This here works fine:
if (eregi("badword",$text)) {
echo ("Text contains the bad word");
} else {
echo ("Text does not contain the bad word"); }
But how can I set two bad words. This here [badword1],[badword2] works fine, but it also matches "bad", but I want it to look for the complete word only.
Thank for helping,nora

This code works perfectly to my knowledge:

<?

$text = "badword1 blaaa blaah poop";

if (eregi("badword1",$text) || eregi("badword2",$text)) {
echo ("Text contains the bad word");
} else {
echo ("Text does not contain the bad word"); }

?>

If you are searching for more that one bad word use | between the bad words.

<?php
$text = "Hello you! How are you? Badword here. And here is another baddy!";

if (eregi("badword|baddy", $text)) {
echo "Contains bad words!";
} else {
echo "Does not contain bad words!";
}

?>

Although above replies are a quick fix, this seems more usable:

$replacement = '*';
$bad_words = array('badword1', 'badword2');
// a simple array which easily can be extended.

// proto bool contains_badwords(reference string $string)
function contains_badwords(&$string) {
// Make the argument a reference, so we can
// change the original string.

global $bad_words, $replacement;
$result = false;

$s_string = strtolower($string);
foreach($bad_words as $badword) {
$badword = strtolower($badword);
if (strpos($s_string, $badword) !== false) {
/ notice the '!==' operator, which means
equal in value AND equal in type, strpos()
might return 0, which is evaluated as false/
$string = eregi_replace($badword,str_repeat($replacement, strlen($badword)), $string);
$result = true;
/ We changed $string here, because we modified

s_string to be the lowercase version for easy checking.. /
}
}
return $result;
}

/ example usage /
$comment = $HTTP_POST_VARS['comment'];
if (contains_badwords($comment)) {
$user->karma--;
$user->write_to_db();
}

Above code changes all badwords that are in the array
$badwords into asterixes..
