word check

[Anon]

I need to know how I can check a value against an array of words to filter out bad words..

I think it would be something like this:

$array = ("sex","screw","beat","root");

if(!eregi("DO SOMETHING", $word)) {
echo "bad or restricted word was found!";
}

can someone help me with this

[non_zero]

$array = array("sex", "screw", "beat", "root");

foreach ($array as $word) {
if (strstr("DO SOMETHING", $word)) {
$error = "bad or restricted word was found!";
}
}
echo $error;

I replaced eregi() with strstr() because...unless you're using wild cards, it won't do you much more good.
