Is it advisable to use a predefined list of bad words or rely on dynamic filtering methods in PHP?

When filtering out bad words in PHP, it is generally advisable to use a predefined list of bad words in addition to dynamic filtering methods. Predefined lists can catch common offensive words, while dynamic filtering methods can handle variations or new words that may arise. Combining both approaches provides a more comprehensive solution for filtering out inappropriate language. 

$badWords = ['badword1', 'badword2', 'badword3']; // Predefined list of bad words

$input = "This is a sentence with a badword1.";

foreach($badWords as $badWord) {
    $input = str_ireplace($badWord, '****', $input); // Replace bad words with asterisks
}

echo $input;
