match a string of words

[jasondavis]

I want to take a submitted data and check to see if a few words are found in it, if they are I would like to mark this data as a spam message,

Example of my code

if($subject!=''){
	$subject=FilterALLHTML($subject);
	$bulletin=FilterHTML($bulletin);
	$bulletin=lineBR($bulletin);
}

I want to check $subject and $body for the words 'votes' 'v o t e s' 'vote' 'v o t e'
and if any of them are found then I would like to make a varibable $spam = 1

Any help greatly appreciated

Would something like this work?

if so how could I amke it into a function

try...

function FilterALLHTML($str)
{
	if(ereg("votes|vote|v o t e s|v o t e", $str))
	{
		$spam = 1;
	}
	return $spam;
}

got it working , thanks =)

<?php
function FilterALLHTML($str)
{
if (preg_match("/(votes|vote|v o t e s|v o t e)/i", $str)) {
        $spam = 1;
    } else {
        $spam = 0;	
	}
    echo $spam;
} 


$mystring = 'please  for me or rate me';
FilterALLHTML($mystring);
echo $spam;

?>
