preg_match array items in string?

Question

Lets say I have an array of bad words:

$badwords = array(\"one\", \"two\", \"three\");

And random string:

$string = \"some          


        

Answer 1

How about this:

$badWords = array('one', 'two', 'three');
$stringToCheck = 'some stringy thing';
// $stringToCheck = 'one stringy thing';

$noBadWordsFound = true;
foreach ($badWords as $badWord) {
  if (preg_match("/\b$badWord\b/", $stringToCheck)) {
    $noBadWordsFound = false;
    break;
  }
}
if ($noBadWordsFound) { ... } else { ... }
