Is it possible to create a comprehensive profanity filter in PHP without using advanced technologies like neural networks or AI?

To create a comprehensive profanity filter in PHP without using advanced technologies like neural networks or AI, you can compile a list of known profane words and then use string manipulation functions to check and replace those words in user input. 

function profanity_filter($input) {
    $profanities = array("badword1", "badword2", "badword3"); // Add more profane words as needed
    $filtered_input = $input;
    
    foreach($profanities as $profanity) {
        $filtered_input = str_ireplace($profanity, "***", $filtered_input);
    }
    
    return $filtered_input;
}

// Example usage
$input = "This is a badword1 sentence with badword2 profanities.";
$filtered_input = profanity_filter($input);
echo $filtered_input;
