[SOLVED] Help Please: Testing a string for list content

[Pazako]

I have a list called $NO_LIST that is the list of things I want rejected if found in a string, it appears to get through, but always allow any words as though it was ignoring my code. Am I missing something? I've tried a few different ways and this is the one I think looks best, thanks for any help you may have!

 

<?php
$NO_LIST = array('punished','scanning','error','fire','L$0','population','tier','month','contest','play','info','winner','payout','score','pot','tracker','pack','display','welcome','ride','fish','hour','sploder','avatars','party','pay ','scan','campaign','tenant','vacant','letter','stats','prize','campus');
function NoList($input)
{
for ($i = 0; $i < count($NO_LIST); $i++)
{
	$input = strtolower($input);
	$pos = strpos($input, $NO_LIST[$i]);
	if ($pos > -1) return false;
}
return true;
}
?>

if (stristr($input,$NO_LIST)){
	return false;
}
else{
	return true;
}
}

$data = "you will be PUnIsHED";
if (!NoList($data)){
print "clean";
}

you can push an array into stristr

So can php functions not see public variables?

 

Also, I need to check with the site 'Im uploading to if all those commands work, if so then thanks much!

oops. forgot. I re-worked my version to handle arrays. nm.

Your functions shouldn't be dependent on outside variables. What if you want to use the same function on a different array?

[Pazako]

The array isn't meant to be changed except for manually at the moment, but I understand what you mean. I have some experience in other programming fields and this kind of thing needs to happen there too. I believe when I first made this that stristr wasn't working because of an old php version on the server - but it all seems fine now. Thanks all for your input. The first response is the one that worked the best
