How does the cs_clear function handle bad words in the CSV file during the import process?

Issue: The cs_clear function can handle bad words in the CSV file during the import process by using a list of banned words and replacing them with a placeholder value. Solution: To handle bad words in the CSV file during the import process, we can create a list of banned words and replace them with a placeholder value before processing the data. This can be achieved by using the str_replace function in PHP.

function cs_clear($data) {
    $banned_words = array("bad_word1", "bad_word2", "bad_word3");
    $placeholder = "****";
    
    foreach($banned_words as $word) {
        $data = str_replace($word, $placeholder, $data);
    }
    
    return $data;
}

// Example usage
$csv_data = "This CSV file contains bad_word1 and bad_word2.";
$cleaned_data = cs_clear($csv_data);
echo $cleaned_data;
