What are the advantages of using a "replace" function over manually checking for bad words in PHP scripts?

Using a "replace" function over manually checking for bad words in PHP scripts provides a more efficient and scalable solution. It automates the process of filtering out inappropriate language, reducing the chance of missing any instances. Additionally, it allows for easy maintenance and updating of the list of bad words without having to modify the code extensively.

$badWords = array("badword1", "badword2", "badword3");
$text = "This is a sentence with badword1 and badword2.";

$filteredText = str_ireplace($badWords, "***", $text);

echo $filteredText;
