How can one efficiently detect and handle bad words in a text using PHP without regular expressions?

Detecting and handling bad words in a text using PHP without regular expressions can be achieved by utilizing the str_ireplace function to replace each bad word with a predefined "clean" word. By creating an array of bad words and their corresponding clean words, we can efficiently filter out inappropriate language from the text. 

<?php

function filterBadWords($text) {
    $badWords = array("badword1" => "cleanword1", "badword2" => "cleanword2");
    
    foreach($badWords as $badWord => $cleanWord) {
        $text = str_ireplace($badWord, $cleanWord, $text);
    }
    
    return $text;
}

$text = "This is a text with badword1 and badword2.";
$filteredText = filterBadWords($text);

echo $filteredText;

?>
