Answer 1

You should be more precise with explaining what you want. If you want a route - use routes.php file to reroute the original URL to your replacement, either than that - use what @vascowhite suggested in his comment to your question.

If it's routing that you need, in your routes.php file in config folder of your application add a line:

$route['imges/fraudsite.zip'] = "imges/fraudsite.html";

If it's just the string you want:

$string = "www.example.com/imges/fraudsite.html";
$string = str_replace(".html", ".zip", $string);

As you have noted in the comments, you need to change everything that goes beyond the last dot to zip, you have to use:

$str = "www.example.com/imges/fraudsite.html";
$str = substr($str, 0, strrpos($str, '.', -1)).".zip";

$ test = "Hello world！";

$test = word_censor($test,"Hello","Bye");

echo $test;

//Bye world!
