PHP redirect when URL contains / match

[Fli]

Hi, i have been searching for good PHP redirect which will redirect urls matching certain phrasse.

Example:
URL contains "?en"

and it will be redirected to english_page.php

OR url contain some badwords like "drug" and it will be redirected to 404.php ...

So i completed this out of what people put on internet:

Example: https://instantcpanelhosting.com/info.php


the code behind it:


<?php
if (strpos($_SERVER["REQUEST_URI"],'?fr') !== false) {
header( 'Location: https://instantcpanelhosting.com/french.php' ) ;

die();
}

if (strpos($_SERVER["REQUEST_URI"],'?sp') !== false) {
header( 'Location: https://instantcpanelhosting.com/spanish.php' ) ;

die();
}

?>

the code must be pasted on the second line right after starting <?php

else it can output "headers already been sent" error

If you want to redirect AND also use friendly URLS, you can use below code.

Example:

/english.php - has contents
/en - no file exist, but visitors will see english.php as /en
